Class JarWildcardStreamLocator

java.lang.Object
  ro.isdc.wro.model.resource.locator.wildcard.DefaultWildcardStreamLocator
      ro.isdc.wro.model.resource.locator.wildcard.JarWildcardStreamLocator

All Implemented Interfaces:

WildcardExpanderHandlerAware, WildcardStreamLocator

public class JarWildcardStreamLocator
extends DefaultWildcardStreamLocator

Resolves classpath resources looking for wildcard patterns in both file system and in JAR files.

The locateStream(String, File) overrides the default strategy defined in DefaultWildcardStreamLocator and it tries to open the provided file as a JAR. If that's successfully opened all entries inside this container will be verified against the wildcard pattern. If the JAR-lookup strategy fails, default strategy is invoked.

For the moment this WildcardStreamLocator only supports a single wildcard.

1.3.6
