Method Detail

doDecode

public int doDecode(DecodingContext context,
                    ByteBufferView buffer)

Description copied from class: BaseMessageHandler

Decode the payload of a message (excluding message prefix -- see StandardBittorrentProtocol.MESSAGE_PREFIX_SIZE) and place it into the provided context.

Specified by:

doDecode in class BaseMessageHandler<Piece>

Parameters:

context - The context to place the decoded message into.

buffer - Buffer to decode from. Buffer.remaining() is set to the declared length of the message. Message payload starts precisely at buffer's Buffer.position().

doEncode

public boolean doEncode(EncodingContext context,
                        Piece message,
                        ByteBuffer buffer)

Description copied from class: BaseMessageHandler

Encode the payload of a message (excluding message prefix -- see StandardBittorrentProtocol.MESSAGE_PREFIX_SIZE) and write it into the provided buffer.

Specified by:

doEncode in class BaseMessageHandler<Piece>

Parameters:

context - Encoding context

buffer - Byte buffer to write to. Encoded message should be placed into the buffer starting with its current position. This method should check if the buffer has sufficient space available, and return false if it's not the case. After this method returns, the buffer's Buffer.position() is used to calculate the size of message's payload, which is then specified in the message's prefix.

Returns:

true if message has been successfully encoded and fully written into the provided buffer
