构造器详细资料

IoBufferDecoder

public IoBufferDecoder(byte[] delimiter)

Creates a new instance that uses specified delimiter byte array as a message delimiter.

参数:

delimiter - an array of characters which delimits messages

IoBufferDecoder

public IoBufferDecoder(int contentLength)

Creates a new instance that will read messages of contentLength bytes.

参数:

contentLength - the exact length to read

方法详细资料

setContentLength

public void setContentLength(int contentLength,
                    boolean resetMatchCount)

Sets the the length of the content line to be decoded. When set, it overrides the dynamic delimiter setting and content length method will be used for decoding on the next decodeOnce call. The default value is -1.

参数:

contentLength - the content length to match

resetMatchCount - delimiter matching is reset if true

setDelimiter

public void setDelimiter(byte[] delim,
                boolean resetMatchCount)

Dynamically sets a new delimiter. Next time decodeFully(IoBuffer) will be called it will use the new delimiter. Delimiter matching is reset only if resetMatchCount is true but decoding will continue from current position. NB : Delimiter LineDelimiter.AUTO is not allowed.

参数:

delim - the new delimiter as a byte array

resetMatchCount - delimiter matching is reset if true

decodeFully

public IoBuffer decodeFully(IoBuffer in)

Will return null unless it has enough data to decode. If contentLength is set then it tries to retrieve contentLength bytes from the buffer otherwise it will scan the buffer to find the data delimiter and return all the data and the trailing delimiter.

参数:

in - the data to decode

返回:

The decoded buffer
