Detailed Description

RecordReader specialized to read compressed records. For VRS internal usage only.

Member Function Documentation

void vrs::CompressedRecordReader::finish ( )

overridevirtual

Discard any unread data.

Reimplemented from vrs::RecordReader.

CompressionType vrs::CompressedRecordReader::getCompressionType ( ) const

overridevirtual

Tell if/how the record was compressed.

int vrs::CompressedRecordReader::read	(	DataReference &	destination,
		uint32_t &	outReadSize
	)

overridevirtual

Read data to a DataReference.

Parameters

destination	DataReference to read data to.
outReadSize	Reference to set to the number of bytes read.
