Method Detail
toByteString
public ByteString toByteString()
Description copied from interface:MessageLiteSerializes the message to aByteStringand returns it. This is just a trivial wrapper aroundMessageLite.writeTo(CodedOutputStream).- Specified by:
toByteStringin interfaceMessageLite
toByteArray
public byte[] toByteArray()
Description copied from interface:MessageLiteSerializes the message to abytearray and returns it. This is just a trivial wrapper aroundMessageLite.writeTo(CodedOutputStream).- Specified by:
toByteArrayin interfaceMessageLite
writeTo
public void writeTo(java.io.OutputStream output) throws java.io.IOExceptionDescription copied from interface:MessageLiteSerializes the message and writes it tooutput. This is just a trivial wrapper aroundMessageLite.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
MessageLite.writeDelimitedTo(OutputStream).- Specified by:
writeToin interfaceMessageLite- Throws:
java.io.IOException
writeDelimitedTo
public void writeDelimitedTo(java.io.OutputStream output) throws java.io.IOExceptionDescription copied from interface:MessageLiteLikeMessageLite.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. UseMessageLite.Builder.mergeDelimitedFrom(InputStream)(or the static methodYourMessageType.parseDelimitedFrom(InputStream)) to parse messages written by this method.- Specified by:
writeDelimitedToin interfaceMessageLite- Throws:
java.io.IOException
