Method Detail

forRelocatedPointerFieldValue

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

Description copied from class: ObjectScanner

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 class ObjectScanner

forNullFieldValue

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

Description copied from class: ObjectScanner

Hook for scanned null field value.

Specified by:

forNullFieldValue in class ObjectScanner

forNonNullFieldValue

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

Description copied from class: ObjectScanner

Hook for scanned non-null field value.

Specified by:

forNonNullFieldValue in class ObjectScanner

forNullArrayElement

public void forNullArrayElement(jdk.vm.ci.meta.JavaConstant array,
                                AnalysisType arrayType,
                                int elementIndex)

Description copied from class: ObjectScanner

Hook for scanned null element value.

Specified by:

forNullArrayElement in class ObjectScanner

forNonNullArrayElement

public void forNonNullArrayElement(jdk.vm.ci.meta.JavaConstant array,
                                   AnalysisType arrayType,
                                   jdk.vm.ci.meta.JavaConstant elementConstant,
                                   AnalysisType elementType,
                                   int elementIndex)

Description copied from class: ObjectScanner

Hook for scanned non-null element value.

Specified by:

forNonNullArrayElement in class ObjectScanner

forScannedConstant

protected void forScannedConstant(jdk.vm.ci.meta.JavaConstant value,
                                  Object reason)

Description copied from class: ObjectScanner

Hook for scanned constant. The subclasses can provide additional processing for the scanned constants.
