Examples of org.objectweb.asm.MethodVisitor.visitFieldInsn()

org.objectweb.asm.MethodVisitor.visitFieldInsn()
Visits a field instruction. A field instruction is an instruction that loads or stores the value of a field of an object. @param opcode the opcode of the type instruction to be visited. Thisopcode is either GETSTATIC, PUTSTATIC, GETFIELD or PUTFIELD. @param owner the internal name of the field's owner class (see {@link Type#getInternalName() getInternalName}). @param name the field's name. @param desc the field's descriptor (see {@link Type Type}).
