protected AbstractReferenceCountedByteBuf(int maxCapacity)

Method Detail

refCnt

public final int refCnt()

Description copied from interface: ReferenceCounted

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

retain

public ByteBuf retain()

Description copied from interface: ReferenceCounted

Increases the reference count by 1.

retain

public ByteBuf retain(int increment)

Description copied from interface: ReferenceCounted

Increases the reference count by the specified increment.

release

public final boolean release()

Description copied from interface: ReferenceCounted

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

Returns:

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

release

public final 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.

Returns:

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

deallocate

protected abstract void deallocate()

Called once refCnt() is equals 0.
