updateConstantClassInfoRefs

protected void updateConstantClassInfoRefs(ConstantPoolTable cpt,
                                           java.lang.String fqClassName,
                                           java.lang.String newFqn)
                                    throws WrongReferenceInConstantPoolTableException

This method reorganizes the given constant pool table in a way that all the Constant Class Info structures pointing to a Constant UTF8 entry having a value equal to fqClassName, will point to the constant pool table entry specified by the third input parameter newFqnIndx.

Parameters:

cpt - The constant pool table to work with

fqClassName - The old fully qualified name we want to look for and replace

newFqnIndx - The index of the new ConstantUTF8 entry in the given cpt, containing the new FQN we want to point to

Throws:

WrongReferenceInConstantPoolTableException

                            throws WrongReferenceInConstantPoolTableException,
                                   DnaSerializationException,
                                   MissingDnaContainerException

Throws:
