This package contains implementations of the {@link org.apache.commons.collections.Closure Closure}, {@link org.apache.commons.collections.Predicate Predicate}, {@link org.apache.commons.collections.Transformer Transformer} and {@link org.apache.commons.collections.Factory Factory} interfaces. These provide simple callbacks for processing with collections. | ||

| StringValueTransformer.java | Class | Transformer implementation that returns the result of calling
String.valueOf on the input object. |
| SwitchClosure.java | Class | Closure implementation calls the closure whose predicate returns true, like a switch statement. |
| SwitchTransformer.java | Class | Transformer implementation calls the transformer whose predicate returns true, like a switch statement. |
| TransformedPredicate.java | Class | Predicate implementation that transforms the given object before invoking
another Predicate. |
| TransformerClosure.java | Class | Closure implementation that calls a Transformer using the input object and ignore the result. |
| TransformerPredicate.java | Class | Predicate implementation that returns the result of a transformer. |
| TruePredicate.java | Class | Predicate implementation that always returns true. |
