Uses of DataOutput in org.apache.lucene.codecs

Methods in org.apache.lucene.codecs with parameters of type DataOutput

Modifier and Type	Method	Description
abstract void	PostingsWriterBase.encodeTerm(long[] longs, DataOutput out, FieldInfo fieldInfo, BlockTermState state, boolean absolute)	Encode metadata as long[] and byte[].
static void	CodecUtil.verifyAndCopyIndexHeader(IndexInput in, DataOutput out, byte[] expectedID)	Expert: verifies the incoming IndexInput has an index header and that its segment ID matches the expected one, and then copies that index header into the provided DataOutput.
