Method Detail

slice

public static ByteBuffer slice(ByteBuffer chunk,
                               int size)

Slice ByteBuffer of required size from big chunk. Passed chunk position will be changed, after the slicing (chunk.position += size).

Parameters:

chunk - big ByteBuffer pool.

size - required slice size.

Returns:

sliced ByteBuffer of required size.

slice

public static ByteBuffer slice(ByteBuffer byteBuffer,
                               int position,
                               int limit)

Get the ByteBuffer's slice basing on its passed position and limit. Position and limit values of the passed ByteBuffer won't be changed. The result ByteBuffer position will be equal to 0, and limit equal to number of sliced bytes (limit - position).

Parameters:

byteBuffer - ByteBuffer to slice/

position - the position in the passed byteBuffer, the slice will start from.

limit - the limit in the passed byteBuffer, the slice will be ended.

Returns:

sliced ByteBuffer of required size.

toStringContent

public static String toStringContent(ByteBuffer byteBuffer,
                                     Charset charset,
                                     int position,
                                     int limit)

setPositionLimit

public static void setPositionLimit(ByteBuffer buffer,
                                    int position,
                                    int limit)

setPositionLimit

public static void setPositionLimit(Buffer buffer,
                                    int position,
                                    int limit)

put

public static void put(ByteBuffer srcBuffer,
                       int srcOffset,
                       int length,
                       ByteBuffer dstBuffer)

get

public static void get(ByteBuffer srcBuffer,
                       byte[] dstBytes,
                       int dstOffset,
                       int length)

put

public static void put(byte[] srcBytes,
                       int srcOffset,
                       int length,
                       ByteBuffer dstBuffer)
