initialize

public int initialize(org.graalvm.word.PointerBase begin,
                      org.graalvm.word.UnsignedWord reservedSize,
                      org.graalvm.nativeimage.c.type.WordPointer basePointer,
                      org.graalvm.nativeimage.c.type.WordPointer endPointer)

Description copied from interface: ImageHeapProvider

Creates a new instance of the image heap.

Specified by:

initialize in interface ImageHeapProvider

Parameters:

begin - If non-null, a specific address where the image heap instance should be created. If null, the image heap instance is created at an arbitrary address.

reservedSize - If begin is non-null, the reserved bytes at that address.

basePointer - An address where a pointer to the start address of the image heap instance will be written. Must not be null.

endPointer - An address where a pointer to the end of the image heap instance will be written. May be null if this value is not required.

Returns:

a result code from CEntryPointErrors.

Specified by:

canUnmapInsteadOfTearDown in interface ImageHeapProvider

tearDown

public int tearDown(org.graalvm.word.PointerBase heapBase)

Description copied from interface: ImageHeapProvider

Disposes an instance of the image heap that was created with this provider.

Specified by:

tearDown in interface ImageHeapProvider
