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.

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.

True if the instance can be flattened and printed as a single table of values. For Arrays and Grids this is always false. For Structures and Sequences the conditions are more complex. The implementation provided by this class always returns false. Other classes should override this implementation.

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.

Write the variable's declaration in a C-style syntax. This function is used to create textual representation of the Data Descriptor Structure (DDS).

This method should be implemented for each of the data type classes (Byte, ..., Grid) when using the DAP class library to build a server. This method is only for DAP servers. The library provides a default definition here which throws an InternalErr exception unless the read_p property has been set. In that case it returns false, indicating that all the data have been read. The latter case can happen when building a constant value that needs to be passed to a function. The variable/constant is loaded with a value when it is created. When implementing a new DAP server, the Byte, ..., Grid data type classes are usually specialized. In each of those specializations read() should be defined to read values from the data source and store them in the object's local buffer. The read() method is called by other methods in this library. When writing read(), follow these rules:

Sends the data from the indicated (local) dataset through the connection identified by the sink parameter. If the data is not already incorporated into the DDS object, read the data from the dataset. This function is only used on the server side of the client/server connection, and is generally only called from the DODSFilter::send() function.
