All Known Implementing Classes:

CardTable.ReferenceToYoungObjectReferenceVisitor, GreyToBlackObjRefVisitor

public interface ObjectReferenceVisitor

Visit an object reference. The visitObjectReference method takes a Pointer as a parameter, but that Pointer is *not* a pointer to an Object, but a Pointer to an object reference.

Method Summary

Modifier and Type	Method and Description
boolean	visitObjectReference(org.graalvm.word.Pointer objRef, boolean compressed) Visit an Object reference.
default boolean	visitObjectReferenceInline(org.graalvm.word.Pointer objRef, boolean compressed) Like visitObjectReference(Pointer), but always inlined for performance.
default boolean	visitObjectReferenceInline(org.graalvm.word.Pointer objRef, int innerOffset, boolean compressed)

Method Detail

visitObjectReference

boolean visitObjectReference(org.graalvm.word.Pointer objRef,
                             boolean compressed)

default boolean visitObjectReferenceInline(org.graalvm.word.Pointer objRef,
                                           boolean compressed)

Like visitObjectReference(Pointer), but always inlined for performance.

visitObjectReferenceInline

default boolean visitObjectReferenceInline(org.graalvm.word.Pointer objRef,
                                           int innerOffset,
                                           boolean compressed)
