Method Detail

getFieldTypeProfile

public jdk.vm.ci.meta.JavaTypeProfile getFieldTypeProfile()

setLocation

protected void setLocation(int location)

setUnmaterializedStaticConstant

protected void setUnmaterializedStaticConstant()

getConstantValue

public jdk.vm.ci.meta.JavaConstant getConstantValue()

hasLocation

public boolean hasLocation()

getLocation

public 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 area.
• static reference fields: the offset (in bytes) into the static object data area.
• static fields that are never written (including but not limited to static final fields): unused, this method must not be called.
