PreFilter

Class Overview

Annotation for specifying a method filtering expression which will be evaluated before a method has been invoked. The name of the argument to be filtered is specified using the filterTarget attribute. This must be a Java Collection implementation which supports the remove method. Pre-filtering isn't supported on array types and will fail if the value of named filter target argument is null at runtime.

For methods which have a single argument which is a collection type, this argument will be used as the filter target.

The annotation value contains the expression which will be evaluated for each element in the collection. If the expression evaluates to false, the element will be removed. The reserved name "filterObject" can be used within the expression to refer to the current object which is being evaluated.
