Class RecursiveFileFilter

java.lang.Object

ptolemy.util.RecursiveFileFilter

All Implemented Interfaces:

java.io.FilenameFilter

public class RecursiveFileFilter
extends java.lang.Object
implements java.io.FilenameFilter

A file name filter that can recursively list files in a directory, including those in subdirectories. When a file name referring to a directory is found, this filter lists the files within that directory again with a new filter in this class.

Constructor Detail

RecursiveFileFilter

public RecursiveFileFilter(boolean recursive,
                           boolean includeFiles,
                           boolean includeDirectories)

Construct a recursive file filter.

Parameters:

recursive - Whether the filter should recursively list subdirectories.

includeFiles - Whether files should be included.

includeDirectories - Whether directories should be included.

RecursiveFileFilter

public RecursiveFileFilter(boolean recursive,
                           boolean includeFiles,
                           boolean includeDirectories,
                           boolean filesOnly,
                           boolean directoriesOnly,
                           java.lang.String fileFilter)

Construct a recursive file filter. This method has four parameters to control whether files and directories are included. Not all combinations make sense, but are required because this code was refactored from two classes that had similar functionality.

Parameters:

recursive - Whether the filter should recursively list subdirectories.

includeFiles - Whether files should be included.

includeDirectories - Whether directories should be included.

filesOnly - Whether only files should be included

directoriesOnly - Whether only directories should be included.

fileFilter - The filter (with ? and * as wildcards) to filter the accepted file names.

                           boolean includeFiles,
                           boolean includeDirectories,

                           boolean escape)

Construct a recursive file filter. This method has four parameters to control whether files and directories are included. Not all combinations make sense, but are required because this code was refactored from two classes that had similar functionality.

Parameters:

recursive - Whether the filter should recursively list subdirectories.

includeFiles - Whether files should be included.

includeDirectories - Whether directories should be included.

filesOnly - Whether only files should be included

directoriesOnly - Whether only directories should be included.

fileFilter - The filter (with ? and * as wildcards) to filter the accepted file names.

escape - True if a string with ? and * as wildcards is to be converted into a Java regular expression. The DirectoryListing actor calls this with a false value.

Method Detail

accept

public boolean accept(java.io.File dir,
                      java.lang.String name)

Return whether the file or directory name in the given directory is accepted.

Specified by:

accept in interface java.io.FilenameFilter

Parameters:

dir - The directory. If directory is null, then it is likely that this method is being called to accept a URL and no File object is instantiated. If directory is not null, then a File object is instantiated.

name - The file or directory name within the given directory.

Returns:

Whether the name is accepted.

getFiles

public java.util.List<java.io.File> getFiles()

Return the list of all files and directories after the filtering. This must be called after all the directories are traversed.

Returns:

The list of files and directories.

listFiles

public static java.io.File[] listFiles(java.io.File directory,
                                       boolean recursive,
                                       boolean includeFiles,
                                       boolean includeDirectories,
                                       java.lang.String fileFilter)

List all the files and directories within the given directory. This method has four parameters to control whether files and directories are included. Not all combinations make sense.

Parameters:

directory - The directory.

recursive - Whether the filter should recursively list subdirectories.

includeFiles - Whether files should be included.

includeDirectories - Whether directories should be included.

fileFilter - The filter (with ? and * as wildcards) to filter the accepted file names.

Returns:

The array of all the files and directories found.

listFiles
