Class AbsoluteNameLocationStrategy

java.lang.Object

org.apache.commons.configuration2.io.AbstractFileLocationStrategy

org.apache.commons.configuration2.io.AbsoluteNameLocationStrategy

All Implemented Interfaces:

FileLocationStrategy

public class AbsoluteNameLocationStrategy
extends AbstractFileLocationStrategy

A specialized implementation of FileLocationStrategy which checks whether the provided file name is already an absolute file name.

This strategy ignores the URL and the base path stored in the passed in FileLocator. It is only triggered by absolute names in the locator's fileName component.

See AbstractFileLocationStrategy learn how to grant an deny URL schemes and hosts.

2.0

locate

public URL locate(FileSystem fileSystem,
 FileLocator locator)

Tries to locate the specified file. The method also expects the FileSystem to be used. Note that the FileLocator object may also contain a FileSystem, but this is optional. The passed in FileSystem should be used, and callers must not pass a null reference for this argument. A concrete implementation has to evaluate the properties stored in the FileLocator object 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 constructs a File object from the locator's file name (if defined). If this results in an absolute file name pointing to an existing file, the corresponding URL is returned.

Parameters:

fileSystem - the FileSystem to be used for this operation

locator - 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
