 ExtensionSchema<?> extensionSchema,
 MessageLite defaultInstance)

Method Details

newSchema

static <T> MessageSetSchema<T> newSchema(UnknownFieldSchema<?,?> unknownFieldSchema,
 ExtensionSchema<?> extensionSchema,
 MessageLite defaultInstance)

newInstance

public T newInstance()

Description copied from interface: Schema

Creates a new instance of the message class.

Specified by:

newInstance in interface Schema<T>

equals

public boolean equals(T message,
 T other)

Description copied from interface: Schema

Determine of the two messages are equal.

Specified by:

equals in interface Schema<T>

hashCode

public int hashCode(T message)

Description copied from interface: Schema

Compute a hashCode for the message.

Specified by:

hashCode in interface Schema<T>

mergeFrom

public void mergeFrom(T message,
 T other)

Description copied from interface: Schema

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

Specified by:

mergeFrom in interface Schema<T>

writeTo

public void writeTo(T message,
 CodedOutputStreamWriter writer)
             throws IOException

Description copied from interface: Schema

Writes the given message to the target CodedOutputStreamWriter.

Specified by:

writeTo in interface Schema<T>

Throws:

IOException

writeUnknownFieldsHelper

private <UT,UB> void writeUnknownFieldsHelper(UnknownFieldSchema<UT,UB> unknownFieldSchema,
 T message,
 CodedOutputStreamWriter writer)
                                       throws IOException

A helper method for wildcard capture of unknownFieldSchema. See: https://docs.oracle.com/javase/tutorial/java/generics/capture.html

Throws:

IOException

mergeFrom

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

Description copied from interface: Schema

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.

Specified by:

mergeFrom in interface Schema<T>

Throws:

IOException

mergeFrom

public void mergeFrom(T message,
 CodedInputStreamReader reader,
 ExtensionRegistryLite extensionRegistry)
               throws IOException

Description copied from interface: Schema

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 Schema.makeImmutable(T).

Specified by:

mergeFrom in interface Schema<T>

Throws:

IOException

mergeFromHelper

private <UT, UB, ET extends FieldSet.FieldDescriptorLite<ET>>
void mergeFromHelper(UnknownFieldSchema<UT,UB> unknownFieldSchema,
 ExtensionSchema<ET> extensionSchema,
 T message,
 CodedInputStreamReader reader,
 ExtensionRegistryLite extensionRegistry)
              throws IOException

A helper method for wildcard capture of unknownFieldSchema. See: https://docs.oracle.com/javase/tutorial/java/generics/capture.html

Throws:

IOException

makeImmutable

public void makeImmutable(T message)

Description copied from interface: Schema

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

Specified by:

makeImmutable in interface Schema<T>
