class | SequenceTest |
This is the interface for the class Sequence. A sequence contains a single set of variables, all at the same lexical level just like a Structure. Like a Structure, a Sequence may contain other compound types, including other Sequences. Unlike a Structure, a Sequence defines a pattern that is repeated N times for a sequence of N elements. It is useful to think of a Sequence as representing a table of values (like a relational database), with each row of the table corresponding to a Sequence instance.'' (This usage can be confusing, since
instance'' also refers to a particular item of class Sequence.) For example:
Sequence { String name; Int32 age; } person;
This represents a Sequence of ``person'' records, each instance of which contains a name and an age:
Fred 34 Ralph 23 Andrea 29 ...
A Sequence can be arbitrarily long, which is to say that its length is not part of its declaration. A Sequence can contain other Sequences:
Sequence { String name; Int32 age; Sequence { String friend; } friend_list; } person;
This is still represented as a single table, but each row contains the elements of both the main Sequence and the nested one:
Fred 34 Norman Fred 34 Andrea Fred 34 Ralph Fred 34 Lisa Ralph 23 Norman Ralph 23 Andrea Ralph 23 Lisa Ralph 23 Marth Ralph 23 Throckmorton Ralph 23 Helga Ralph 23 Millicent Andrea 29 Ralph Andrea 29 Natasha Andrea 29 Norman ... .. ...
Internally, the Sequence is represented by a vector of vectors. The members of the outer vector are the members of the Sequence. This includes the nested Sequences, as in the above example.
NB: Note that in the past this class had a different behavior. It held only one row at a time and the deserialize(...) method had to be called from within a loop. This is no longer true. Now the deserailize(...) method should be called once and will read the entire sequence's values from the server. All the values are now stored in an instance of Sequence, not just a single row's.
Because the length of a Sequence is indeterminate, there are changes to the behavior of the functions to read this class of data. The read()
function for Sequence must be written so that successive calls return values for successive rows of the Sequence.
Similar to a C structure, you refer to members of Sequence elements with a .'' notation. For example, if the Sequence has a member Sequence called
Tom'' and Tom has a member Float32 called shoe_size'', you can refer to Tom's shoe size as
Tom.shoe_size''.

Reads the class data into the memory referenced by val. The caller should either allocate enough storage to val to hold the class data or set *val
to null. If *val is NULL, memory will be allocated by this function with new()
. If the memory is allocated this way, the caller is responsible for deallocating that memory. Array and values for simple types are stored as C would store an array.
@param val A pointer to a pointer to the memory into which the class data will be copied. If the value pointed to is NULL, memory will be allocated to hold the data, and the pointer value modified accordingly. The calling program is responsible for deallocating the memory references by this pointer. @return The size (in bytes) of the information copied to <i>val</i>.

This function checks the class instance for internal consistency. This is important to check for complex constructor classes. For BaseType, an object is semantically correct if it has both a non-null name and type.
For example, an Int32 instance would return FALSE if it had no name or no type defined. A Grid instance might return FALSE for more complex reasons, such as having Map arrays of the wrong size or shape.
This function is used by the DDS class, and will rarely, if ever, be explicitly called by a DODS application program. A variable must pass this test before it is sent, but there may be many other stages in a retrieve operation where it would fail.
msg | A returned string, containing a message indicating the source of any problem. |
all | For complex constructor types (Grid, Sequence, Structure), this flag indicates whether to check the semantics of the member variables, too. |

This method used to read a single row at a time. Now the entire sequence is read at once. The method used to return True to indicate that more data needed to be deserialized and False when the sequence was completely read. Now it simply returns false. This might seem odd, but making this method return false breaks existing software the least.

Return a count of the total number of variables in this variable. This is used to count the number of variables held by a constructor variable - for simple type and vector variables it always returns 1.
For compound data types, there are two ways to count members. You can count the members, or you can count the simple members and add that to the count of the compound members. For example, if a Structure contains an Int32 and another Structure that itself contains two Int32 members, the element count of the top-level structure could be two (one Int32 and one Structure) or three (one Int32 by itself and two Int32's in the subsidiary Structure). Use the leaves parameter to control which kind of counting you desire.
leaves | This parameter is only relevant if the object contains other compound data types. If FALSE, the function counts only the data variables mentioned in the object's declaration. If TRUE, it counts the simple members, and adds that to the sum of the counts for the compound members. This parameter has no effect for simple type variables. |

This method is used to evaluate a constraint and based on those results load the Sequence variable with data. This simulates having a server call the serialize() method and a client call the deserialize() method without the overhead of any IPC. Use this method on the server-side to 'load the d_values field with data' so that other code and work with those data.
The somewhat odd algorithm used by serialize() is largely copied here, so comments about logic in serialize() and the related methods apply here as well.

Returns the number of elements in a Sequence object. Note that this is not the number of items in a row, but the number of rows in the complete sequence object. To be meaningful, this must be computed after constraint expression (CE) evaluation. The purpose of this function is to facilitate translations between Sequence objects and Array objects, particularly when the Sequence is too large to be transferred from the server to the client in its entirety.
This function, to be useful, must be specialized for the API and data format in use.

This method contains the relational operators used by the constraint expression evaluator in the DDS class. Each class that wants to be able to evaluate relational expressions must overload this function. The implementation in BaseType throws an InternalErr exception. The DAP library classes Byte, ..., Url provide specializations of this method. It is not meaningful for classes such as Array because relational expressions using Array are not supported.
The op argument refers to a table generated by bison from the constraint expression parser. Use statements like the following to correctly interpret its value:
switch (op) { case EQUAL: return i1 == i2; case NOT_EQUAL: return i1 != i2; case GREATER: return i1 > i2; case GREATER_EQL: return i1 >= i2; case LESS: return i1 < i2; case LESS_EQL: return i1 <= i2; case REGEXP: throw Error("Regular expressions are not supported for integer values"); default: throw Error("Unknown operator"); }
This function is used by the constraint expression evaluator.
b | Compare the value of this instance with b. |
op | An integer index indicating which relational operator is implied. Choose one from the following: EQUAL , NOT_EQUAL , GREATER , GREATER_EQL , LESS , LESS_EQL , and REGEXP . |

Write the variable's declaration in a C-style syntax. This function is used to create textual representation of the Data Descriptor Structure (DDS). See The DODS User Manual for information about this structure.
A simple array declaration might look like this:
Float64 lat[lat = 180];
While a more complex declaration (for a Grid, in this case), would look like this:
Grid { ARRAY: Int32 sst[time = 404][lat = 180][lon = 360]; MAPS: Float64 time[time = 404]; Float64 lat[lat = 180]; Float64 lon[lon = 360]; } sst;
out | The output stream on which to print the declaration. |
space | Each line of the declaration will begin with the characters in this string. Usually used for leading spaces. |
print_semi | A boolean value indicating whether to print a semicolon at the end of the declaration. |
constraint_info | A boolean value indicating whether constraint information is to be printed with the declaration. If the value of this parameter is TRUE, print_decl() prints the value of the variable's send_p() flag after the declaration. |
constrained | If this boolean value is TRUE, the variable's declaration is only printed if is the send_p() flag is TRUE. If a constraint expression is in place, and this variable is not requested, the send_p() flag is FALSE. |

Read row number row of the Sequence. The values of the row are obtained by calling the read() method of the sequence. The current row just read is stored in the Sequence instance along with its row number. If a selection expression has been supplied, rows are counted only if they satisfy that expression.
Note that we can only advance in a Sequence. It is not possible to back up and read a row numbered lower than the current row. If you need that you will need to replace the serialize() method with one of your own.

Serialize a Sequence.
Leaf Sequences must be marked as such (see DDS::tag_nested_sequence()), as must the top most Sequence.
How the code works. Methods called for various functions are named in brackets:
Sending a one-level sequence:
Dataset { Sequence { Int x; Int y; } flat; } case_1;
Serialize it by reading successive rows and sending all of those that satisfy the CE. Before each row, send a start of instance (SOI) marker. Once all rows have been sent, send an End of Sequence (EOS) marker.[serialize_leaf].
Sending a nested sequence:
Dataset { Sequence { Int t; Sequence { Int z; } inner; } outer; } case_2;
Serialize by reading the first row of outer and storing the values. Do not evaluate the CE [serialize_parent_part_one]. Call serialize() for inner and read each row for it, evaluating the CE for each row that is read. After the first row of inner is read and satisfies the CE, write out the SOI marker and values for outer [serialize_parent_part_two], then write the SOI and values for the first row of inner. Continue to read and send rows of inner until the last row has been read. Send EOS for inner [serialize_leaf]. Now read the next row of outer and repeat. Once outer is completely read, send its EOS marker.
Notes:
For a nested Sequence, the child sequence must follow all other types in the parent sequence (like the example). There may be only one nested Sequence per level.
CE evaluation happens only in a leaf sequence.

In a nested Sequence, the Sequence which holds the leaf elements is special because it during the serialization of this Sequence's data that constraint Expressions must be evaluated. If CEs are evaluated at the upper levels, then valid data may not be sent because it was effectively hidden from the serialization and evaluation code (see the documentation for the serialize_leaf() method).
The notion of the leaf Sequence needs to be modified to mean the lowest level of a Sequence where data are to be sent. Suppose there's a two level Sequence, but that only fields from the top level are to be sent. Then that top level is also the leaf Sequence and should be marked as such. If the lower level is marked as a leaf Sequence, then no values will ever be sent since the send_p property will always be false for each field and it's the call to serialize_leaf() that actually triggers transmission of values (because it's not until the code makes it into serialize_leaf() that it knows there are values to be sent.

Transfer attributes from a DAS object into this variable. Because of the rough history of the DAS object and the way that various server code built the DAS, this is necessarily a heuristic process. The intent is that this method will be overridden by handlers that need to look for certain patterns in the DAS (e.g., hdf4's odd variable_dim_n; where n = 0, 1, 2, ...) attribute containers.
There should be a one-to-one mapping between variables and attribute containers. However, in some cases one variable has attributes spread across several top level containers and in some cases one container is used by several variables

Store the value pointed to by val in the object's internal buffer. This function does not perform any checks, so users must be sure that the thing pointed to can actually be stored in the object's buffer.
Only simple objects (Int, Float, Byte, and so on) and arrays of these simple objects may be stored using this function. To put data into more complex constructor types, use the functions provided by that class.
@param val A pointer to the data to be inserted into the class data buffer. @param reuse A boolean value, indicating whether the class internal data storage can be reused or not. If this argument is TRUE, the class buffer is assumed to be large enough to hold the incoming data, and it is <i>not</i> reallocated. If FALSE, new storage is allocated. If the internal buffer has not been allocated at all, this argument has no effect. This is currently used only in the Vector class. @return The size (in bytes) of the information copied from <i>val</i>. @see Grid @see Vector::val2buf

This version of width simply returns the same thing as width() for simple types and Arrays. For Structure it returns the total size if constrained is false, or the size of the elements in the current projection if true.
constrained | If true, return the size after applying a constraint. |
