Class StylesheetCache.DepResolver

Object

StylesheetCache.DepResolver

All Implemented Interfaces:

URIResolver

Enclosing class:

StylesheetCache

private static class StylesheetCache.DepResolver
extends Object
implements URIResolver

While loading a stylesheet, we record all the sub-stylesheets referenced by it, so that we can form a list of all the dependencies. That way, if any of them are changed, the stylesheet will be auto- matically reloaded. We do it by implementing a pass-through URIResolver that adds a dependency and then does the normal URIResolver work.
