Class StandardMethodCodec

  • All Implemented Interfaces:
    MethodCodec

    public final class StandardMethodCodec
    extends Object
    implements MethodCodec
    A MethodCodec using the Flutter standard binary encoding.

    This codec is guaranteed to be compatible with the corresponding StandardMethodCodec on the Dart side. These parts of the Flutter SDK are evolved synchronously.

    Values supported as method arguments and result payloads are those supported by StandardMessageCodec.

      • decodeMethodCall

        public MethodCall decodeMethodCall​(ByteBuffer methodCall)
        Description copied from interface: MethodCodec
        Decodes a message call from binary.
        Specified by:
        decodeMethodCall in interface MethodCodec
        Parameters:
        methodCall - the binary encoding of the method call as a ByteBuffer.
        Returns:
        a MethodCall representation of the bytes between the given buffer's current position and its limit.
      • encodeSuccessEnvelope

        public ByteBuffer encodeSuccessEnvelope​(Object result)
        Description copied from interface: MethodCodec
        Encodes a successful result into a binary envelope message.
        Specified by:
        encodeSuccessEnvelope in interface MethodCodec
        Parameters:
        result - The result value, possibly null.
        Returns:
        a ByteBuffer containing the encoding between position 0 and the current position.
      • encodeErrorEnvelope

        public ByteBuffer encodeErrorEnvelope​(String errorCode,
                                              String errorMessage,

        Description copied from interface: MethodCodec
        Encodes an error result into a binary envelope message.
        Specified by:
        encodeErrorEnvelope in interface MethodCodec
        Parameters:
        errorCode - An error code String.
        errorMessage - An error message String, possibly null.
        errorDetails - Error details, possibly null. Consider supporting Throwable in your codec. This is the most common value passed to this field.
        Returns:
        a ByteBuffer containing the encoding between position 0 and the current position.
      • encodeErrorEnvelopeWithStacktrace

        public ByteBuffer encodeErrorEnvelopeWithStacktrace​(String errorCode,
                                                            String errorMessage,

        encodeErrorEnvelopeWithStacktrace in interface MethodCodec
        Parameters:
        errorCode - An error code String.
        errorMessage - An error message String, possibly null.
        errorDetails - Error details, possibly null. Consider supporting Throwable in your codec. This is the most common value passed to this field.
        errorStacktrace - Platform stacktrace for the error. possibly null.
        Returns:
        a ByteBuffer containing the encoding between position 0 and the current position.
