Member Function Documentation

DtAttributeDecoder DtHlaStateDecoder::addDecoder	(	RTI::AttributeHandle	h,
		DtAttributeDecoder	func
	)

Add/Remove a decoding function for the attribute specified by handle.

Returns the decoding function which is replaced by the add/remove. Note: This is non-virtual, since it is typically called by constructors.

Referenced by DtF18EntityDecoder::DtF18EntityDecoder().

DtAttributeDecoder DtHlaStateDecoder::addDecoder	(	char *	attrName,
		DtAttributeDecoder	func,
		bool	complain = true
	)

Add/Remove a decoding function for the attribute specified by name.

Complain flag determines whether to print a warning if the attribute does not exist in the FOM. Returns the decoding function which is replaced by the add/remove. Note: This is non-virtual, since it is typically called by constructors.

virtual DtHlaStateDecoder* DtHlaStateDecoder::clone ( ) const

virtual

Returns a new-ed clone of this object.

Reimplemented in DtBaseEntityDecoder.

virtual DtHlaStateDecoder* DtHlaStateDecoder::clone ( DtObjClassDesc *  classDesc ) const

virtual

Returns a new-ed clone of this object which corresponds to the class description classDesc.

Use this function if you want a subclass in the FOM to use the same decoder as its parent

Reimplemented in DtBaseEntityDecoder.

virtual void DtHlaStateDecoder::copyDecFuncs ( const DtHlaStateDecoder &  orig )

protectedvirtual

virtual void DtHlaStateDecoder::decode ( const DtStateMsg &  msg, DtStateRepository *  stateRep  ) const

virtual

Decode the state message into the state repository.

Reimplemented in DtBaseEntityDecoder, and DtPhysicalEntityDecoder.

virtual void DtHlaStateDecoder::decodeAttribute ( DtStateRepository *  stateRep, const RTI::AttributeHandleValuePairSet &  attrs, unsigned long  pairSetIndex  ) const

protectedvirtual

Decode the attribute at the specified index in the attribute handle pair set.

Reimplemented in DtGenericObjectDecoder.

DtHlaStateDecoder::DtAttributeDecoder DtHlaStateDecoder::decoder ( const RTI::AttributeHandle &  handle ) const

inlinevirtual

Get the attribute decoder for the specified handle.

References myDecoderList.

char * DtHlaStateDecoder::decodingBuffer ( int  length )

inlinestatic

Returns a pointer to a buffer that can be used to copy data obtained from a phvps.

If the buffer isn't large enough to contain the data, more space will be allocated to it.

References DtDecodingBuffer().

RTI::ObjectClassHandle DtHlaStateDecoder::objectClassHandle ( ) const

Get the object's class handle.

myReportedWarnings is an array for keeping track of which warnings have been already issued.

This variable is set in const functions. The Decoders need to be const, but we would like to warn people only once.
