Method Detail

currentMagazine

AdaptivePoolingAllocator.Magazine currentMagazine()

detachFromMagazine

void detachFromMagazine()

attachToMagazine

void attachToMagazine(AdaptivePoolingAllocator.Magazine magazine)

touch

public AdaptivePoolingAllocator.Chunk touch(java.lang.Object hint)

Description copied from interface: ReferenceCounted

Records the current access location of this object with an additional arbitrary information for debugging purposes. If this object is determined to be leaked, the information recorded by this operation will be provided to you via ResourceLeakDetector.

Specified by:

touch in interface ReferenceCounted

refCnt

public int refCnt()

Description copied from interface: ReferenceCounted

Returns the reference count of this object. If 0, it means this object has been deallocated.

Specified by:

refCnt in interface ReferenceCounted

retain

public AdaptivePoolingAllocator.Chunk retain()

Description copied from interface: ReferenceCounted

Increases the reference count by 1.

Specified by:

retain in interface ReferenceCounted

retain

public AdaptivePoolingAllocator.Chunk retain(int increment)

Description copied from interface: ReferenceCounted

Increases the reference count by the specified increment.

Specified by:

retain in interface ReferenceCounted

touch

public AdaptivePoolingAllocator.Chunk touch()

Description copied from interface: ReferenceCounted

Records the current access location of this object for debugging purposes. If this object is determined to be leaked, the information recorded by this operation will be provided to you via ResourceLeakDetector. This method is a shortcut to touch(null).

Specified by:

touch in interface ReferenceCounted

release

public boolean release()

Description copied from interface: ReferenceCounted

Decreases the reference count by 1 and deallocates this object if the reference count reaches at 0.

Specified by:

release in interface ReferenceCounted

Returns:

true if and only if the reference count became 0 and this object has been deallocated

release

public boolean release(int decrement)

Description copied from interface: ReferenceCounted

Decreases the reference count by the specified decrement and deallocates this object if the reference count reaches at 0.

Specified by:

release in interface ReferenceCounted

Returns:

true if and only if the reference count became 0 and this object has been deallocated

deallocate

private void deallocate()

shouldReleaseSuboptimalChunkSuze

private static boolean shouldReleaseSuboptimalChunkSuze(int givenSize,
                                                        int preferredSize)

readInitInto

public void readInitInto(AdaptivePoolingAllocator.AdaptiveByteBuf buf,
                         int size,
                         int maxCapacity)
