public class BasePathLocationStrategy extends Object implements FileLocationStrategy
A specialized implementation of FileLocationStrategy
which tries to construct a file path from the locator's
base path and file name.
This strategies ignores the URL stored in the passed in FileLocator
. It generates a path by concatenating the
base path (if present) and the file name. If the resulting path points to a valid file, the corresponding URL is
returned.

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 uses utility methods from FileLocatorUtils
to generate a File
from
the locator's base path and file name. If this File
exists, its URL is returned.locate
