Method Detail

getType

public SctpChunk.Type getType()

Specified by:

getType in interface SctpChunk

getLength

public int getLength()

Description copied from interface: SctpChunk

This value represents the size of the chunk in bytes, including the Chunk Type, Chunk Flags, Chunk Length, and Chunk Value fields. Therefore, if the Chunk Value field is zero-length, the Length field will be set to 4. The Chunk Length field does not count any chunk padding.

Chunks (including Type, Length, and Value fields) are padded out by the sender with all zero bytes to be a multiple of 4 bytes long. This padding MUST NOT be more than 3 bytes in total. The Chunk Length value does not include terminating padding of the chunk. However, it does include padding of any variable-length parameter except the last parameter in the chunk. The receiver MUST ignore the padding.

Note: A robust implementation should accept the chunk whether or not the final padding has been included in the Chunk Length.

Specified by:

getLength in interface SctpChunk

Returns:

getHeader

public Buffer getHeader()

Description copied from interface: SctpChunk

Get the raw header of this SCTP Chunk

Specified by:

getHeader in interface SctpChunk

getValue

public Buffer getValue()

Description copied from interface: SctpChunk

Get the Chunk Value excluding any potential padding that may have been included on the wire.

Specified by:

getValue in interface SctpChunk

Returns:

getPadding

public int getPadding()

Specified by:

getPadding in interface SctpChunk

Returns:

getFlags

public byte getFlags()

Specified by:

getFlags in interface SctpChunk

getValueLength

public int getValueLength()

Description copied from interface: SctpChunk

The length of the value of the chunk.

Note that the length as encoded into the Chunk "header" includes the 4 bytes containing the size of the fields making up the header. This length is JUST the length of the actual value. Also, it does NOT include padding (if any).
