Method Detail

locate
public URL locate(FileSystem fileSystem, FileLocator locator)
Tries to locate the specified file. The method also expects theFileSystemto be used. Note that theFileLocatorobject may also contain aFileSystem, but this is optional. The passed inFileSystemshould be used, and callers must not pass a null reference for this argument. A concrete implementation has to evaluate the properties stored in theFileLocatorobject and try to match them to an existing file. If this can be done, a corresponding URL is returned. Otherwise, result is null. Implementations should not throw an exception (unless parameters are null) as there might be alternative strategies which can find the file in question. This implementation looks up the locator's file name as a resource on the class path.- Specified by:
locatein interfaceFileLocationStrategy- Parameters:
fileSystem- theFileSystemto be used for this operationlocator- the object describing the file to be located- Returns:
- a URL pointing to the referenced file if location was successful; null if the file could not be resolved
