Examples of org.apache.commons.collections4.Transformer

org.apache.commons.collections4.iterators.NodeListIterator
Defines a functor interface implemented by classes that transform one object into another.
A Transformer converts the input object to the output object. The input object should be left unchanged. Transformers are typically used for type conversions, or extracting data from an object.
Standard implementations of common transformers are provided by {@link TransformerUtils}. These include method invocation, returning a constant, cloning and returning the string value. @param < I> the input type to the transformer @param < O> the output type from the transformer @since 1.0 @version $Id: Transformer.java 1469004 2013-04-17 17:37:03Z tn $
