Add Utiltities method to DataUtilities class
--------------------------------------------
Key: GEOT-3041
URL: http://jira.codehaus.org/browse/GEOT-3041
Project: GeoTools
Issue Type: Wish
Components: core main
Affects Versions: 2.6.3
Reporter: Daniele Romagnoli
Assignee: Jody Garnett
Fix For: 2.6.4
Attachments: gt-main.patch
Some modules involving data I/O usually perform several required checks before
performing input/output operations.
As an instance, they check if a specified file exists/can be read, if a
specified path refers to an existing/readable directory, if a specified file is
of a specific supported type.
For this reason it will be useful to add some utilities method to the
DataUtilities class:
public static boolean checkFileReadable(final File file, final Logger logger):
Checks that a File is a real file, exists and is readable. An optional logger
(which can be null) can be specified to get fine logging details.
public static String checkDirectory(String directoryPath)
Checks that the provided directory path refers to an existing/readable
directory.
public static IOFileFilter excludeFilters(final IOFileFilter inputFilter,
IOFileFilter... filters)
Returns a IOFileFilter obtained by excluding from the first input filter
argument, the additional filter rguments.
public static IOFileFilter includeFilters(final IOFileFilter inputFilter,
IOFileFilter... filters)
Returns a IOFileFilter obtained by adding to the first input filter argument,
the additional filter arguments.
Note that some of these new methods leverage on commons-io and then that
dependency should be added to the pom.
The attached patch will allow to add the methods and dependency.
