All Implemented Interfaces:

Retainable, RetainableByteBuffer, RetainableByteBuffer.Mutable

Enclosing interface:

RetainableByteBuffer

public static class RetainableByteBuffer.Pooled
extends RetainableByteBuffer.FixedCapacity

A pooled buffer that knows the pool from which it was allocated. Any methods that may need to allocated additional buffers (e.g. copy()) will use the pool.

Method Details

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.

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.

copy

public RetainableByteBuffer copy()

Description copied from interface: RetainableByteBuffer

Creates a deep copy of this RetainableByteBuffer that is entirely independent

Returns:

A copy of this RetainableByteBuffer
