unsigned int edm::StreamSerializer::compressBuffer ( unsigned char *  inputBuffer, unsigned int  inputSize, std::vector< unsigned char > &  outputBuffer, int  compressionLevel  )

static

Compresses the data in the specified input buffer into the specified output buffer. Returns the size of the compressed data or zero if compression failed.

int edm::StreamSerializer::serializeEvent	(	EventPrincipal const &	eventPrincipal,
		ParameterSetID const &	selectorConfig,
		bool	use_compression,
		int	compression_level,
		SerializeDataBuffer &	data_buffer,
		ModuleCallingContext const *	mcc
	)

Serializes the specified event into the specified event message.

make a char* as a data member, tell ROOT to not adapt it, but still use it. initialize it to 1M, let ROOT resize if it wants, then delete it in the dtor.

change the call to not take an eventMessage, add a member function to return the address of the place that ROOT wrote the serialized data.

return the length of the serialized object and the actual length if compression has been done (may want to cache these lengths in this object instead.

the caller will need to copy the data from this object to its final destination in the EventMsgBuilder.

int edm::StreamSerializer::serializeRegistry	(	SerializeDataBuffer &	data_buffer,
		const BranchIDLists &	branchIDLists,
		ThinnedAssociationsHelper const &	thinnedAssociationsHelper
	)

Serializes the product registry (that was specified to the constructor) into the specified InitMessage.
