Constructor. ValidateChunkCount). Validate ValidateChunkCount KVariableChunkCount

Destructor

Appends the specified data chunk to the compound type's sequence of chunks.

Provides the number of discrete data chunks of which the compound type is composed.

Removes the chunk at the specified position in the chunk sequence.

Provides the TElementInfo data for the specified element.

Indicates if the specified element can be read from.

Resets the compound base, removing all data chunk references.

Sets the expected chunk count. This flag is used by the derived class to indicate the number of chunks which make up the compound type. A value of KVariableChunkCount indicates that the type is of variable rather than fixed length (e.g. a list of elements). If KVariableChunkCount is specified then the derived class's ValidChunkCount method is invoked when the compound type is validated (ValidateChunkCount).

Validates that the number of chunks making up the compound type is valid. This method is invoked on variable length compound types by the default Valid implementation. Valid KVariableChunkCount

Indicates if the specified element can be written to.

The read and write data stream states.

This flag is used by derived classes to signal the use of just-in-time techniques during construction from a write data stream. CMTPTypeCompoundBase

Initialisation value for TElementInfo data values that are non applicable for an element, e.g. when specifying iFlatChunkInfo values for non-flat elements such as arrays and strings.

This flag is used by the derived class to indicate that the number of chunks making up the compound type is variable rather than fixed (e.g. a list of elements.)

Ordered data type element chunk table.

This flag indicates the number of chunks which make up the compound type. A value of KVariableChunkCount indicates that the type is of variable rather than fixed length (e.g. a list of elements). If KVariableChunkCount is specified then the derived class's ValidChunkCount method is invoked by the default Valid implementation.

This flag indicates that the compound data type uses just-in-time techniques when constructing iteself from a write data stream. Typically this is used for types whose final structure is dependant upon data contained within the data stream itself, e.g. a dataset with an element whose data type is determined by meta data which precedes the element in the data stream.

The read data stream data chunk table index. Note that this is declared mutable to allow state updates while processing a read data stream.

The read data stream state variable. Note that this is declared mutable to allow state updates while processing a read data stream.

The write data stream data chunk table index.

The write data stream error state.

The write data stream state variable.
