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

public void mergeFrom(T message,
                      T other)

writeTo in interface Schema<T>

Throws:

java.io.IOException

writeUnknownFieldsHelper

private <UT,UB> void writeUnknownFieldsHelper(UnknownFieldSchema<UT,UB> unknownFieldSchema,

               throws java.io.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.
