- Observe the first parameter and return value of method, and expand the nested attributes of the object to 4 levels:
watch {{class-pattern}} {{method-pattern}} {{'{ params[0],returnObj }'}} -x 4
- When the value of the first parameter of the method is 5, the second parameter and return value are output, and the object is expanded 4 layers:
watch {{class-pattern}} {{method-pattern}} {{'{ params[1],returnObj }'}} {{'"5".equals(params[0])'}} -x 4
- When the method returns or an exception occurs, observe the count property of the second parameter:
watch {{class-pattern}} {{method-pattern}} {{'{ params[1].count }'}} -e -s
