Class ArrayRetainableByteBufferPool.Tracking

java.lang.Object

org.eclipse.jetty.io.ArrayRetainableByteBufferPool

org.eclipse.jetty.io.ArrayRetainableByteBufferPool.Tracking

All Implemented Interfaces:

RetainableByteBufferPool, Dumpable

Enclosing class:

ArrayRetainableByteBufferPool

public static class ArrayRetainableByteBufferPool.Tracking
extends ArrayRetainableByteBufferPool

A variant of ArrayRetainableByteBufferPool that tracks buffer acquires/releases, useful to identify buffer leaks.

Use getLeaks() when the system is idle to get the ArrayRetainableByteBufferPool.Tracking.Buffers that have been leaked, which contain the stack trace information of where the buffer was acquired.

acquire

public RetainableByteBuffer acquire(int size,
 boolean direct)

Description copied from interface: RetainableByteBufferPool

Acquires a memory buffer from the pool.

Specified by:

acquire in interface RetainableByteBufferPool

Overrides:

acquire in class ArrayRetainableByteBufferPool

Parameters:

size - The size of the buffer. The returned buffer will have at least this capacity.

direct - true if a direct memory buffer is needed, false otherwise.

Returns:

a memory buffer with position and size set to 0.
