                         OffHeapMemoryAllocator allocator)

Method Detail

putMemoryAddressOffset

public void putMemoryAddressOffset(int offset,
                                   long address)

getMemoryAddressOffset

public long getMemoryAddressOffset(int offset)

getMemoryAddressOffsetNoTraceIfAbsent

public long getMemoryAddressOffsetNoTraceIfAbsent(int offset)

deallocate

public void deallocate()

toStream

public LongStream toStream()

Returns a stream of longs that are all of the various memory locations

Returns:

stream of the various memory locations

removeAll

public LongStream removeAll()

Removes all the address lookups by setting them to 0. This method returns a LongStream that contains all of valid (non zero) addresses that were present during this operation.

Returns:

stream with the valid memory pointers to stored values

removeAll

public LongStream removeAll(int offset,
                            int count)

Removes all the address lookups by setting them to 0 within the given offset, limiting the removal to only a specific count of addresses. This method returns a LongStream that contains all of valid (non zero) addresses that were present during this operation.

Parameters:

offset - offset into the block

count - how many pointers to look at

Returns:

stream with the valid memory pointers to stored values

getPointerCount

public int getPointerCount()
