Class UnknownFieldSet.Field

java.lang.Object

com.google.protobuf.UnknownFieldSet.Field

Enclosing class:

UnknownFieldSet

public static final class UnknownFieldSet.Field
extends java.lang.Object

Represents a single field in an UnknownFieldSet.

A Field consists of five lists of values. The lists correspond to the five "wire types" used in the protocol buffer binary format. The wire type of each field can be determined from the encoded form alone, without knowing the field's declared type. So, we are able to parse unknown values at least this far and separate them. Normally, only one of the five lists will contain any values, since it is impossible to define a valid message type that declares two different types for the same field number. However, the code is designed to allow for the case where the same unknown field number is encountered using multiple different wire types.

Field is an immutable class. To construct one, you must use a UnknownFieldSet.Field.Builder.

Method Detail

newBuilder

public static UnknownFieldSet.Field.Builder newBuilder()

Construct a new UnknownFieldSet.Field.Builder.

newBuilder

public static UnknownFieldSet.Field.Builder newBuilder(UnknownFieldSet.Field copyFrom)

Construct a new UnknownFieldSet.Field.Builder and initialize it to a copy of copyFrom.

getDefaultInstance

public static UnknownFieldSet.Field getDefaultInstance()

Get an empty Field.

getVarintList

public java.util.List<java.lang.Long> getVarintList()

Get the list of varint values for this field.

getFixed32List

public java.util.List<java.lang.Integer> getFixed32List()

Get the list of fixed32 values for this field.

getFixed64List

public java.util.List<java.lang.Long> getFixed64List()

Get the list of fixed64 values for this field.

getLengthDelimitedList

public java.util.List<ByteString> getLengthDelimitedList()

Get the list of length-delimited values for this field.

getGroupList

public java.util.List<UnknownFieldSet> getGroupList()

Get the list of embedded group values for this field. These are represented using UnknownFieldSets rather than Messages since the group's type is presumably unknown.

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

getIdentityArray

private java.lang.Object[] getIdentityArray()

Returns the array of objects to be used to uniquely identify this UnknownFieldSet.Field instance.

toByteString

public ByteString toByteString(int fieldNumber)

Serializes the message to a ByteString and returns it. This is just a trivial wrapper around writeTo(int, CodedOutputStream).

writeTo

public void writeTo(int fieldNumber,
                    CodedOutputStream output)
             throws java.io.IOException

Serializes the field, including field number, and writes it to output.

Throws:

java.io.IOException

getSerializedSize

public int getSerializedSize(int fieldNumber)

Get the number of bytes required to encode this field, including field number.

writeAsMessageSetExtensionTo

public void writeAsMessageSetExtensionTo(int fieldNumber,
                                         CodedOutputStream output)
                                  throws java.io.IOException

Serializes the field, including field number, and writes it to output, using MessageSet wire format.

Throws:

java.io.IOException

writeTo

void writeTo(int fieldNumber,
             Writer writer)
      throws java.io.IOException

Serializes the field, including field number, and writes it to writer.

Throws:

java.io.IOException

writeAsMessageSetExtensionTo

private void writeAsMessageSetExtensionTo(int fieldNumber,
                                          Writer writer)
                                   throws java.io.IOException

Serializes the field, including field number, and writes it to writer, using MessageSet wire format.

Throws:

java.io.IOException

getSerializedSizeAsMessageSetExtension

public int getSerializedSizeAsMessageSetExtension(int fieldNumber)

Get the number of bytes required to encode this field, including field number, using MessageSet wire format.
