Method Detail

getLocation

int getLocation()

The offset or index of the field. The value depends on the kind of field:

• instance fields: the offset (in bytes) from the origin of the instance.
• static fields of primitive type: the offset (in bytes) into the static primitive data array StaticFieldsSupport.getStaticPrimitiveFields().
• static reference fields: the offset (in bytes) into the static object data array StaticFieldsSupport.getStaticObjectFields().
• static fields that are never written (including but not limited to static final fields): unused, this method must not be called.

isAccessed

boolean isAccessed()

isWritten

boolean isWritten()

getStorageKind

jdk.vm.ci.meta.JavaKind getStorageKind()
