Constructor Detail

ChunkedImageHeapLayouter

public ChunkedImageHeapLayouter(ImageHeapInfo heapInfo,
                                boolean compressedNullPadding)

Method Detail

createPartitionsArray

protected ChunkedImageHeapPartition[] createPartitionsArray(int count)

Specified by:

createPartitionsArray in class AbstractImageHeapLayouter<ChunkedImageHeapPartition>

createPartition

protected ChunkedImageHeapPartition createPartition(String name,
                                                    boolean containsReferences,
                                                    boolean writable,
                                                    boolean hugeObjects)

Specified by:

createPartition in class AbstractImageHeapLayouter<ChunkedImageHeapPartition>

getHugeObjectThreshold

protected long getHugeObjectThreshold()

Description copied from class: AbstractImageHeapLayouter

The size in bytes at and above which an object should be assigned to the huge partitions.

Overrides:

getHugeObjectThreshold in class AbstractImageHeapLayouter<ChunkedImageHeapPartition>

doLayout

protected ImageHeapLayoutInfo doLayout(ImageHeap imageHeap)

Specified by:

doLayout in class AbstractImageHeapLayouter<ChunkedImageHeapPartition>

writeMetadata

public void writeMetadata(ByteBuffer imageHeapBytes)

Description copied from interface: ImageHeapLayouter

Based on the layout decided during an earlier call to ImageHeapLayouter.layout(com.oracle.svm.core.image.ImageHeap, int), fill the image heap in the supplied buffer with additional data structures, if any. At this time, the buffer already contains the laid out objects, which are not meant to be modified in this step.

Specified by:

writeMetadata in interface ImageHeapLayouter

Overrides:

writeMetadata in class AbstractImageHeapLayouter<ChunkedImageHeapPartition>
