internalNioBuffer

public ByteBuffer internalNioBuffer(int index,
                           int length)

Description copied from class: ByteBuf

Internal use only: Exposes the internal NIO buffer.

Specified by:

internalNioBuffer in class ByteBuf

nioBuffer

public ByteBuffer nioBuffer(int index,
                   int length)

Description copied from class: ByteBuf

Exposes this buffer's sub-region as an NIO ByteBuffer. The returned buffer shares the content with this buffer, while changing the position and limit of the returned NIO buffer does not affect the indexes and marks of this buffer. This method does not modify readerIndex or writerIndex of this buffer. Please note that the returned NIO buffer will not see the changes of this buffer if this buffer is a dynamic buffer and it adjusted its capacity.

Specified by:

nioBuffer in class ByteBuf
