Eric Milles updated GROOVY-5359:
--------------------------------
Labels: performance (was: )
> static propertyMissing catches inherited static methods
> -------------------------------------------------------
>
> Key: GROOVY-5359
> URL: https://issues.apache.org/jira/browse/GROOVY-5359
> Project: Groovy
> Issue Type: Improvement
> Components: groovy-runtime
> Reporter: OC
> Assignee: Eric Milles
> Priority: Minor
> Labels: performance
>
> When static missing properties are catched, the handler is called also when
> an inherited static method is called.
> It is not a serious problem, but it feels weird. Either it should be changed
> (if possible with reasonably small effort), or thoroughly documented.
> Also, it should be documented that if the handler throws a
> MissingPropertyException, it gets silently eaten up and the static method is
> called all right. On the other hand, any other exception goes all the way up
> to the user-level harness if any, which is generally rather undesirable.
> Here's a code sample which illustrates the problem, along with the proper
> exception thrown so as the method is properly called:
> {code}
> class Foo {
> static def inheritedStaticMethod() {
> println "Allright, Kilroy's here"
> }
> }
> class Test extends Foo {
> static def main(av) {
> // need to catch all class-level missing properties
> Object.metaClass.static.propertyMissing={
> println "Property $it of ${delegate.simpleName} missing."
> // simulated 'found valid dynamic property' case
> if (it.startsWith('f')) return "(${delegate.simpleName}.$it OK)"
> // oops, we did not find valid d.p, so we
> throw new MissingPropertyException("No valid DP for
> ${delegate.simpleName}.$it")
> }
> println "Checking the handler: ${Object.foo} ${Foo.foo} ${Test.foo}
> ${String.foo}"
> inheritedStaticMethod()
> }
> }
> {code}
