Class WildcardExpanderModelTransformer

java.lang.Object
  ro.isdc.wro.model.transformer.WildcardExpanderModelTransformer

All Implemented Interfaces:

Transformer<WroModel>

public class WildcardExpanderModelTransformer
extends Object
implements Transformer<WroModel>

A decorator which looks up for resources containing wildcards and replaces them with the corresponding collection of specific resources. For example, a resource of this type:

<js>/path/to/**.js</js>

can be transformed into:

<js>/path/to/a1.js</js>
<js>/path/to/a2.js</js>
<js>/path/to/a3.js</js>

This model transformation is also known as wildcard expander, because it mutates the model after it is built by adding resources to the group which contains resources with wildcard uri.

Since:

1.4.0
