Class WireFormat

java.lang.Object

org.infinispan.protostream.impl.WireFormat

public final class WireFormat
extends java.lang.Object

Defines numeric constants for wire types. Also helps extracting the wire type and field number out of a tag.

Field Summary

Fields

Modifier and Type	Field and Description
private static int	TAG_TYPE_BITS The lower 3 bits of the 32 bit tag are used for encoding the wire type.
private static int	TAG_TYPE_MASK Bit mask used for extracting the lower 3 bits which represent the wire type.
static int	WIRETYPE_END_GROUP
static int	WIRETYPE_FIXED32
static int	WIRETYPE_FIXED64
static int	WIRETYPE_LENGTH_DELIMITED
static int	WIRETYPE_START_GROUP
static int	WIRETYPE_VARINT
