Interface ClasspathAssetAliasManager

All Known Implementing Classes:

ClasspathAssetAliasManagerImpl

@UsesMappedConfiguration(value=java.lang.String.class)
public interface ClasspathAssetAliasManager

Used as part of the support for classpath Assets, to convert the Asset's Resource to a URL that can be accessed by the client. The asset path, within the classpath, is converted into a shorter virtual path (one that, typically, includes some kind of version number).

Service configuration is a map from aliases (short names) to complete names. Names should not start or end end with a slash.

Method Summary

String	toResourcePath(String clientURL) Reverses toClientURL(String), stripping off the asset prefix, and re-expanding any aliased folders back to complete folders.
