Method Detail

forRelocatedPointerFieldValue

public void forRelocatedPointerFieldValue(jdk.vm.ci.meta.JavaConstant receiver,
                                          AnalysisField field,
                                          jdk.vm.ci.meta.JavaConstant fieldValue)

Description copied from interface: ObjectScanningObserver

Hook for relocated pointer scanned field value.

For relocated pointers the value is only known at runtime after methods are relocated, which is pretty much the same as a field written at runtime: we do not have a constant value.

Specified by:

forRelocatedPointerFieldValue in interface ObjectScanningObserver

forNullFieldValue

public void forNullFieldValue(jdk.vm.ci.meta.JavaConstant receiver,
                              AnalysisField field)

Description copied from interface: ObjectScanningObserver

Hook for scanned null field value.

Specified by:

forNullFieldValue in interface ObjectScanningObserver

forNonNullFieldValue

public void forNonNullFieldValue(jdk.vm.ci.meta.JavaConstant receiver,
                                 AnalysisField field,

Description copied from interface: ObjectScanningObserver

Hook for scanned non-null field value.

Specified by:

forNonNullFieldValue in interface ObjectScanningObserver

forNullArrayElement
