Examples of org.objectweb.asm.CodeVisitor.visitTypeInsn()

org.objectweb.asm.CodeVisitor.visitTypeInsn()
Visits a type instruction. A type instruction is an instruction that takes a type descriptor as parameter. @param opcode the opcode of the type instruction to be visited. This opcodeis either NEW, ANEWARRAY, CHECKCAST or INSTANCEOF. @param desc the operand of the instruction to be visited. This operand ismust be a fully qualified class name in internal form, or the type descriptor of an array type (see {@link Type Type}).
