Utilities.directoryList

Returns a vector of file names in a given directory that satisfy a specified filter pattern.

Syntax

public static Vector 
directoryList(String path,
              String filter,
              boolean recurse, 
              int maxcount)

Parameters

path

Path name of the directory to search.

filter

File filter, that typically includes wildcards. The two wildcards supported are:

• *, which matches any string (or no string).
• ?, which matches any single character.

For example, the filter "*.bat" would match any file ending in the suffix .bat. The filter "???" would match any file whose name contains exactly three characters. Setting filter to null tells directoryList to match all files in the specified path.

recurse

A true value tells the method to look for matching files (based on the filter) in the subdirectories of the supplied path. A false value tells the method to restrict the search to the directory specify in path.

maxcount

Specifies the maximum number of files that will be returned in the vector. It is possible, though rare, to generate outofmemory exceptions by specifying a very large number.

Description

The directoryList method returns a vector of file names in a given directory that satisfy a specified filter pattern. Both the directory path and the filter are converted using osSafeSpec().

Returns

Returns the vector of file names in the path that match the filter.

Example

The following code finds all the Java source code files in directory /users/bob and all its subdirectories. Only the first 100 matching files will be returned:

String Directory = "/users/bob";
String Filter = "*.java";
boolean Recurse = true;
int Maxcount = 100;
Vector JavaSourceFiles = Utilities.directoryList(Directory,
                                  Filter, Recurse, Maxcount);
errNum = cs.GetErrno();
