Method Details

getByteBuffer

public ByteBuffer getByteBuffer()

Description copied from interface: RetainableByteBuffer

Get the wrapped, not null, ByteBuffer.

If the implementation contains multiple buffers, they are coalesced to a single buffer before being returned. If the content is too large for a single ByteBuffer, then the content should be access with RetainableByteBuffer.writeTo(Content.Sink, boolean).

Specified by:

getByteBuffer in interface RetainableByteBuffer

Returns:

the wrapped, not null, ByteBuffer

slice

public RetainableByteBuffer slice(long length)

Description copied from interface: RetainableByteBuffer

Get a partial slice of the buffer. This is equivalent to RetainableByteBuffer.slice().RetainableByteBuffer.limit(long), but may be implemented more efficiently.

Specified by:

slice in interface RetainableByteBuffer

Parameters:

length - The number of bytes to slice, which may beyond the limit and less than the capacity, in which case it will ensure some spare capacity in the slice.

Returns:

A sliced RetainableByteBuffer sharing the first length bytes of this buffers data and reference count, but with independent position. The buffer is retained by this call.
