Method Detail

getId

UUID getId()

The allocation identifier.

getSlice

ByteBuffer getSlice()

The allocated ByteBuffer.slice().

release

void release()
             throws InterruptedException

Release this allocation.

Note: The implementation is encouraged to release the associated direct ByteBuffer if there are no remaining allocations against it and MAY made the slice of the buffer available for reallocation.

Note: An InterruptedException MAY be thrown. This allows us to handle cases where a concurrent process (such as a query) was halted and its component threads were interrupted. By looking for the interrupt, we can avoid attempts to release an allocation in some thread where the entire DirectBufferPoolAllocator.IAllocationContext has already been released by another thread.

Throws:

InterruptedException
