Method Details

acquire

public ByteBuffer acquire(int size,
 boolean direct)

Deprecated.

Description copied from interface: ByteBufferPool

Requests a ByteBuffer of the given size.

The returned buffer may have a bigger capacity than the size being requested but it will have the limit set to the given size.

Specified by:

acquire in interface ByteBufferPool

Parameters:

size - the size of the buffer

direct - whether the buffer must be direct or not

Returns:

the requested buffer

See Also:

• ByteBufferPool.release(ByteBuffer)

release

public void release(ByteBuffer buffer)

Deprecated.

Description copied from interface: ByteBufferPool

Returns a ByteBuffer, usually obtained with ByteBufferPool.acquire(int, boolean) (but not necessarily), making it available for recycling and reuse.

Specified by:

release in interface ByteBufferPool

Parameters:

buffer - the buffer to return

See Also:

• ByteBufferPool.acquire(int, boolean)

remove

public void remove(ByteBuffer buffer)

Deprecated.

Description copied from interface: ByteBufferPool

Removes a ByteBuffer that was previously obtained with ByteBufferPool.acquire(int, boolean).

The buffer will not be available for further reuse.

Specified by:

remove in interface ByteBufferPool

Parameters:

buffer - the buffer to remove

See Also:

• ByteBufferPool.acquire(int, boolean)
• ByteBufferPool.release(ByteBuffer)

clearTracking

@ManagedAttribute("Clears the tracking data")
public void clearTracking()

Deprecated.

Clears the tracking data returned by getLeakedAcquires(), getLeakedReleases(), getLeakedResources().

getLeakedAcquires

@ManagedAttribute("The number of acquires that produced a leak")
public long getLeakedAcquires()

Deprecated.

Returns:

count of ByteBufferPool.acquire() calls that detected a leak

getLeakedReleases

@ManagedAttribute("The number of releases that produced a leak")
public long getLeakedReleases()

Deprecated.

Returns:

count of ByteBufferPool.release() calls that detected a leak

getLeakedRemoves

@ManagedAttribute("The number of removes that produced a leak")
public long getLeakedRemoves()

Deprecated.

Returns:

count of ByteBufferPool.remove() calls that detected a leak

getLeakedResources

@ManagedAttribute("The number of resources that were leaked")
public long getLeakedResources()

Deprecated.

Returns:

count of resources that were acquired but not released
