Package com.google.protobuf

Interface Schema<T>

All Known Implementing Classes:

MessageSchema, MessageSetSchema

@ExperimentalApi
@CheckReturnValue
interface Schema<T>

A runtime schema for a single protobuf message. A schema provides operations on message instances such as serialization/deserialization.

Method Summary

Modifier and Type	Method	Description
boolean	equals(T message, T other)	Determine of the two messages are equal.
int	getSerializedSize(T message)	Compute the serialized size of the message.
int	hashCode(T message)	Compute a hashCode for the message.
boolean	isInitialized(T message)	Checks whether all required fields are set.
void	makeImmutable(T message)	Marks repeated/map/extension/unknown fields as immutable.
void	mergeFrom(T message, byte[] data, int position, int limit, ArrayDecoders.Registers registers)	Like the above but parses from a byte[] without extensions.
void	mergeFrom(T message, CodedInputStreamReader reader, ExtensionRegistryLite extensionRegistry)	Reads fields from the given CodedInputStreamReader and merges them into the message.
void	mergeFrom(T message, T other)	Merge values from other into message.
T	newInstance()	Creates a new instance of the message class.
void	writeTo(T message, CodedOutputStreamWriter writer)	Writes the given message to the target CodedOutputStreamWriter.

Method Detail

writeTo

void writeTo(T message,
             CodedOutputStreamWriter writer)
      throws java.io.IOException

Writes the given message to the target CodedOutputStreamWriter.

Throws:

java.io.IOException

mergeFrom

void mergeFrom(T message,
               CodedInputStreamReader reader,
               ExtensionRegistryLite extensionRegistry)
        throws java.io.IOException

Reads fields from the given CodedInputStreamReader and merges them into the message. It doesn't make the message immutable after parsing is done. To make the message immutable, use makeImmutable(T).

Throws:

java.io.IOException

mergeFrom

void mergeFrom(T message,
               byte[] data,
               int position,
               int limit,
               ArrayDecoders.Registers registers)
        throws java.io.IOException

Like the above but parses from a byte[] without extensions. Entry point of fast path. Note that this method may throw IndexOutOfBoundsException if the input data is not valid protobuf wire format. Protobuf public API methods should catch and convert that exception to InvalidProtocolBufferException.

Throws:

java.io.IOException

makeImmutable

void makeImmutable(T message)

Marks repeated/map/extension/unknown fields as immutable.

isInitialized

boolean isInitialized(T message)

Checks whether all required fields are set.

newInstance

T newInstance()

Creates a new instance of the message class.

equals

boolean equals(T message,
               T other)

Determine of the two messages are equal.

hashCode

int hashCode(T message)

Compute a hashCode for the message.

mergeFrom

void mergeFrom(T message,
               T other)

Merge values from other into message. This method doesn't make the message immutable. To make the message immutable after merging, use makeImmutable(T).

getSerializedSize

int getSerializedSize(T message)

Compute the serialized size of the message.
