Field Detail

BRIDGE_REF

private static final Bridge BRIDGE_REF

Bridge is used to access unsafe methods used to read and write arbitrary data members in objects. This is very fast, and completely ignores access protections including final on fields. NOTE WELL: Unsafe is capable of causing severe damage to the VM, including causing the VM to dump core. get and put calls must only be made with offsets obtained from objectFieldOffset calls. Because of the dangerous nature of Unsafe, its use must be carefully protected.

Use bridge with code generated by codegen to copy objects. This method must be invoked from inside a doPrivileged call.

Throws:

ReflectiveCopyException

createCopy

public java.lang.Object createCopy(java.lang.Object source)
                            throws ReflectiveCopyException

Description copied from class: ClassCopierBase

Create a copy of source. The copy may or may not be fully initialized. This method must always be overridden in a subclass.

Specified by:

createCopy in class ClassCopierBase

Throws:

ReflectiveCopyException

doCopy

public java.lang.Object doCopy(java.util.Map<java.lang.Object,java.lang.Object> oldToNew,
                               java.lang.Object source,
                               java.lang.Object result)
                        throws ReflectiveCopyException

Description copied from class: ClassCopierBase

Do the copying of data from source to result. This just returns the result by default, but it may be overrideden in a subclass. When this method completes, result must be fully initialized.

Overrides:

doCopy in class ClassCopierBase

Throws:

ReflectiveCopyException
