Method Detail

• getSIZES

   final FieldSizes getSIZES()

  Helper object that defines the fixed sizes of individual fields in the RSCP protocol.

• getPOSITIONS

   final FieldPositions getPOSITIONS()

  Helper object that defines the fixed positions of the individual fields in a FrameHeader.

• getFIXED_VALUES

   final FixedValues getFIXED_VALUES()

  Helper object that defines some fixed values from the RSCP protocol

• getTagsByHexString

   final Map<String, Tag> getTagsByHexString()

  Map containing all known tags. The key is the respective hex code as string in lowercase with leading prefix 0x

• fromHexString

   final static ByteArray fromHexString(String $self)

  Creates a byte array from the string assuming that the string is in valid hex format.

  The call works for strings with and without prefix 0x. There is no validation if the string is a valid hex string.

  Returns:

  ByteArray representation of the hex string

  Since:

  2.0

• toHexString

   final static String toHexString(ByteArray $self)

  Creates a string from the ByteArray in hex format, without prefix

  Returns:

  Hex String representation of the ByteArray

  Since:

  2.0

• crc32

   final static Long crc32(ByteArray $self)

  Calculates the CRC32 checksum of the ByteArray.

  Returns:

  Checksum of the ByteArray

  Since:

  2.0

• fillCRC32forFrame

   final static ByteBuffer fillCRC32forFrame(ByteBuffer $self)

  Calculates the CRC32 checksum assuming that the byte buffer is an E3DC RSCP frame. This means that the checksum is formed over all bytes of the buffer, minus the last 4. See SIZES.

  Returns:

  ByteBuffer with filled checksum.

• emptyByteBuffer

   final static ByteBuffer emptyByteBuffer(Integer size)

  Creates an empty ByteBuffer with the specified size size in bytes.

  The ByteOrder, as required by E3DC, is ByteOrder.LITTLE_ENDIAN.

  Parameters:

  size - Size of the ByteBuffer in byte

  Returns:

  Empty ByteBuffer object, with the requested size, in ByteOrder.LITTLE_ENDIAN order.

  Since:

  2.0

• tagFromByteArray

   final static Tag tagFromByteArray(ByteArray byteArray)

  Returns the Tag for the given byteArray.

  If the tag is not known, an instance of UnknownTag is returned.

  Returns:

  Tag object to the given byteArray.

  Since:

  2.0
