Output Values

The purpose of most methods is to produce some output, for example a string for display in the case of a Format Method. In every such case, the output is stored into designated variables. Methods do not return values and may not transmit results through parameters.

Output variables are described in detail in the following sections covering each method type. Here is a summary:

Output Variable for Each Method Type
Method Type	Output Variable	Significance
Boolean	bool bOk	true or false
Branch	int iOutput	reference to branch field in a table entry
ByteStreamFramer	bool bFrameTransformed; CArray<WORD,WORD> ausLowIndex; CArray<WORD,WORD> ausHighIndex; CArray<BYTE,BYTE> abVirtualFrame ebsfReturn eAction	info so that the layer can be parsed.
Format	CString csOutput	formatted string for display
Frame Transformer	bool bFrameTransformed; CArray<WORD,WORD> ausLowIndex; CArray<WORD,WORD> ausHighIndex; CArray<BYTE,BYTE> abVirtualFrame	(see "Frame Transformers")
NextProtocol	__int64 i64Output	numeric code for protocol
NextProtocolOffset	int iOutput	offset in bytes
NextProtocolSize	int iOutput	size in bytes
PreProcessing		(none)
Processing		(none)
PostProcessing		(none)
Retrieval	__int64 i64FieldValue	adjusted value
Retrieval	int iFieldSize	size in bits
Size	int iOutput	bit count
StartBit	int iOutput	bit offset
Tag	CString csOutput	tag name
Verify	bool bOk	true or false
Verify	CString csOutput	expected result if verification fails
