ResourceLoaderImpl
public ResourceLoaderImpl(XMLCDeferredParsingFactory factory)
- Parameters:
factory
- the XMLC deferred parsing factory
getResource
public URL getResource(String[] candidatePaths)
- Delegates to
getPathURLFromResourceDirOrClasspath(String[])
- Specified by:
getResource
in interface ResourceLoader
- Parameters:
candidatePaths
- an array of candidate paths from which to load a
resource in order of preference- Returns:
- a URL corresponding to one of the candidatePaths or null if not
found
getPathURLFromResourceDirOrClasspath
protected URL getPathURLFromResourceDirOrClasspath(String[] candidatePaths)
- Iterates over candidatePaths, where each resource is first searched for
in resource dirs with fallback to the classpath. This allows one to make
files available in the classloader, for fallback, while maintaining the
capability of overriding classloader-provided files by placing equivalent
files in configured resource dirs. This makes for simple development
and flexible deployment.
Paths are expected to be relative, i.e., no leading slash, with
directory/package names separated by forward slashes regardless of
operating system platform.
- Parameters:
candidatePaths
- an array of candidate paths from which to load a
resource in order of preference- Returns:
- a URL corresponding to one of the candidatePaths or null if not
found

- Parameters:
candidatePath
- a candidate path from which to load a resource- Returns:
- a URL corresponding the candidatePath or null if not found
