Class JdoPropertySetterAdapter

java.lang.Object
  org.objectweb.asm.MethodAdapter
      org.jpox.enhancer.asm.JdoPropertySetterAdapter

All Implemented Interfaces:

org.objectweb.asm.MethodVisitor

public class JdoPropertySetterAdapter
extends org.objectweb.asm.MethodAdapter

Adapter for property setter methods in JDO-enabled classes. This adapter processes the setXXX method and

• Creates jdoSetXXX with the same code as was present in setXXX
• Changes setXXX to have the code below

When detachable this will be (CHECK_WRITE variant)

 void setZZZ(YYY zzz)
 {
     if (jdoFlags != 0 && jdoStateManager != null)
         jdoStateManager.setStringField(this, 2, jdoGetZZZ(), zzz);
     else
     {
         jdoSetXXX(zzz);
         if (jdoIsDetached() == true)
             ((BitSet) jdoDetachedState[3]).set(2);
     }
 }
 

and when not detachable

 void setZZZ(YYY zzz)
 {
     if (jdoFlags > 0 && jdoStateManager != null)
         jdoStateManager.setObjectField(this, 2, jdoGetZZZ(), zzz);
     jdoSetXXX(zzz);
 }
 

There are other variants for MEDIATE_WRITE and NORMAL_WRITE
