extends Object
Class Inheritance
Imports
java.io.IOException
This class is used internally by the Protocol Buffer library and generated message implementations. It is public only because those generated messages do not reside in the protobuf package. Others should not use this class directly. This class contains constants and helper functions useful for dealing with the Protocol Buffer wire format.

Method Summary

Modifier and TypeMethod and Description
public static final int

Returns:

length of array
getRepeatedFieldArrayLength(final CodedInputByteBufferNano
stream input, pointing to the byte after the first tag
input, final int
repeated field tag just read
tag)

Computes the array length of a repeated field.

public static int
getTagFieldNumber(final int tag)

Given a tag value, determines the field number (the upper 29 bits).

pack-priv static int
getTagWireType(final int tag)

Given a tag value, determines the wire type (the lower 3 bits).

pack-priv static int
makeTag(final int fieldNumber, final int wireType)

Makes a tag value given a field number and wire type.

public static boolean

Returns:

true unless the tag is an end-group tag.
parseUnknownField(final CodedInputByteBufferNano input, final int tag)

Parses an unknown field.

Method Detail

getRepeatedFieldArrayLengthback to summary
public static final int getRepeatedFieldArrayLength(final CodedInputByteBufferNano input, final int tag) throws IOException

Computes the array length of a repeated field. We assume that in the common case repeated fields are contiguously serialized but we still correctly handle interspersed values of a repeated field (but with extra allocations). Rewinds to current input position before returning.

Parameters
input:CodedInputByteBufferNano

stream input, pointing to the byte after the first tag

tag:int

repeated field tag just read

Returns:int

length of array

getTagFieldNumberback to summary
public static int getTagFieldNumber(final int tag)

Given a tag value, determines the field number (the upper 29 bits).

getTagWireTypeback to summary
pack-priv static int getTagWireType(final int tag)

Given a tag value, determines the wire type (the lower 3 bits).

makeTagback to summary
pack-priv static int makeTag(final int fieldNumber, final int wireType)

Makes a tag value given a field number and wire type.

parseUnknownFieldback to summary
public static boolean parseUnknownField(final CodedInputByteBufferNano input, final int tag) throws IOException

Parses an unknown field. This implementation skips the field.

Generated messages will call this for unknown fields if the store_unknown_fields option is off.

Returns:boolean

true unless the tag is an end-group tag.
