BRIDGE_REF	back to summary
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.

All Implemented Interfaces

org.glassfish.pfl.dynamic.copyobject.impl.ClassCopierOrdinaryImpl.ClassFieldCopier

Use bridge to copy objects. Now that we are on JDK 5, this has not been known to fail on any VM (unlike on JDK 1.4.1). Note that the reflective copier should work now on JDK 5, due to the change in suppressAccessChecks that supports writing to final fields. This copier also supports @Copy annotations on fields.
