Examples of org.mvel2.asm.MethodVisitor.visitVarInsn()

org.mvel2.asm.MethodVisitor.visitVarInsn()
Visits a local variable instruction. A local variable instruction is an instruction that loads or stores the value of a local variable. @param opcode the opcode of the local variable instruction to be visited. This opcode is either ILOAD, LLOAD, FLOAD, DLOAD, ALOAD, ISTORE, LSTORE, FSTORE, DSTORE, ASTORE or RET. @param var the operand of the instruction to be visited. This operand is the index of a local variable.
