Pattern: Explicit call to or()
Issue: -
This rule detects when the or(Object) method is called directly in code instead of using the | operator. A groovier way to express this: a.or(b) is this: a | b. This rule can be configured to ignore this.or(Object) using the ignoreThisReference property. It defaults to true, so even or(x) will not trigger a violation. This is the default because it is commonly used in Grails criteria.
This rule also ignores all calls to super.or(Object).
