Methods

toByteArray()

public byte[] toByteArray()

Serializes the message to a byte array and returns it. This is just a trivial wrapper around #writeTo(CodedOutputStream).

If this message requires more than Integer.MAX_VALUE bytes to encode, the behavior is unpredictable. It may throw a runtime exception or truncate or slice the data.

Returns
Type	Description
byte[]

toByteString()

public ByteString toByteString()

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

If this message requires more than Integer.MAX_VALUE bytes to encode, the behavior is unpredictable. It may throw a runtime exception or truncate or slice the data.

Returns
Type	Description
ByteString

writeDelimitedTo(OutputStream output)

public void writeDelimitedTo(OutputStream output)

Like #writeTo(OutputStream), but writes the size of the message as a varint before writing the data. This allows more data to be written to the stream after the message without the need to delimit the message data yourself. Use Builder#mergeDelimitedFrom(InputStream) (or the static method YourMessageType.parseDelimitedFrom(InputStream)) to parse messages written by this method.

Parameter
Name	Description
output	OutputStream

Exceptions
Type	Description
IOException

writeTo(OutputStream output)

public void writeTo(OutputStream output)

Serializes the message and writes it to output. This is just a trivial wrapper around #writeTo(CodedOutputStream). This does not flush or close the stream.

NOTE: Protocol Buffers are not self-delimiting. Therefore, if you write any more data to the stream after the message, you must somehow ensure that the parser on the receiving end does not interpret this as being part of the protocol message. This can be done e.g. by writing the size of the message before the data, then making sure to limit the input to that size on the receiving end (e.g. by wrapping the InputStream in one which limits the input). Alternatively, just use #writeDelimitedTo(OutputStream).

Parameter
Name	Description
output	OutputStream

Type	Description
IOException
