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

org.mvel2.asm.MethodVisitor.visitIntInsn()
Visits an instruction with a single int operand. @param opcode the opcode of the instruction to be visited. This opcode is either BIPUSH, SIPUSH or NEWARRAY. @param operand the operand of the instruction to be visited.
When opcode is BIPUSH, operand value should be between Byte.MIN_VALUE and Byte.MAX_VALUE.
When opcode is SIPUSH, operand value should be between Short.MIN_VALUE and Short.MAX_VALUE.
When opcode is NEWARRAY, operand value should be one of {@link Opcodes#T_BOOLEAN}, {@link Opcodes#T_CHAR}, {@link Opcodes#T_FLOAT}, {@link Opcodes#T_DOUBLE}, {@link Opcodes#T_BYTE}, {@link Opcodes#T_SHORT}, {@link Opcodes#T_INT} or {@link Opcodes#T_LONG}.
