Examples of org.drools.asm.MethodVisitor.visitMethodInsn()

org.drools.asm.MethodVisitor.visitMethodInsn()
Visits a method instruction. A method instruction is an instruction that invokes a method. @param opcode the opcode of the type instruction to be visited. Thisopcode is either INVOKEVIRTUAL, INVOKESPECIAL, INVOKESTATIC or INVOKEINTERFACE. @param owner the internal name of the method's owner class (see {@link Type#getInternalName() getInternalName}). @param name the method's name. @param desc the method's descriptor (see {@link Type Type}).

                                   getInternalType( classDef.getClassName() ),
                                   field.getName(),
                                   getTypeDescriptor( field.getTypeName() ) );
