Method Detail

newBuffer

public static CompositeBuffer newBuffer()

Construct CompositeBuffer.

Returns:

new CompositeBuffer

newBuffer

public static CompositeBuffer newBuffer(MemoryManager memoryManager)

newBuffer

public static CompositeBuffer newBuffer(MemoryManager memoryManager,
                                        Buffer... buffers)

newBuffer

public static CompositeBuffer newBuffer(MemoryManager memoryManager,
                                        Buffer[] buffers,
                                        boolean isReadOnly)

disposeOrder

public CompositeBuffer.DisposeOrder disposeOrder()

Returns the order in which internal Buffers will be disposed.

Returns:

CompositeBuffer.DisposeOrder

disposeOrder

public CompositeBuffer disposeOrder(CompositeBuffer.DisposeOrder disposeOrder)

Sets the order in which internal Buffers will be disposed.

Parameters:

disposeOrder -

Returns:

this buffer

append

public abstract CompositeBuffer append(Buffer buffer)

prepend

public abstract CompositeBuffer prepend(Buffer buffer)

Description copied from interface: Buffer

Prepend data from header.position() to header.limit() to the current buffer. This will change the value returned by buffer()!

Specified by:

prepend in interface Buffer

Parameters:

buffer - the data to prepend

Returns:

the new buffer

underlying

public abstract Object[] underlying()

Description copied from interface: Buffer

Return the underlying buffer

Specified by:

underlying in interface Buffer

Returns:

the underlying buffer

removeAll

public abstract void removeAll()

Removes underlying Buffers, without disposing

allowInternalBuffersDispose

public abstract void allowInternalBuffersDispose(boolean allow)

allowInternalBuffersDispose

public abstract boolean allowInternalBuffersDispose()

bulk

public abstract int bulk(CompositeBuffer.BulkOperation operation)

Iterates over Buffer bytes from Buffer.position() to Buffer.limit() and lets CompositeBuffer.BulkOperation examine/change the buffer content;

Parameters:

operation - CompositeBuffer.BulkOperation

Returns:

Buffer position the processing was stopped on, or -1, if processing reached the limit.

bulk

public abstract int bulk(CompositeBuffer.BulkOperation operation,
                         int position,
                         int limit)

Iterates over Buffer bytes from position to limit and lets CompositeBuffer.BulkOperation examine/change the buffer content;

Parameters:

operation - CompositeBuffer.BulkOperation

Returns:

Buffer position the processing was stopped on, or -1, if processing reached the limit.

replace

public abstract boolean replace(Buffer oldBuffer,
                                Buffer newBuffer)

Replace one internal Buffer with another one.

Parameters:

oldBuffer - the Buffer to replace.

newBuffer - the new Buffer.

Returns:

true, if the oldBuffer was found and replaced, or false otherwise.
