Package org.apache.commons.vfs2.filter
Class WildcardFileFilter
java.lang.Object
org.apache.commons.vfs2.filter.WildcardFileFilter
- All Implemented Interfaces:
Serializable,FileFilter
Filters files using the supplied wildcards.
This filter selects files and directories based on one or more wildcards. Testing is case-sensitive by default, but this can be configured.
The wildcard matcher uses the characters '?' and '*' to represent a single or multiple wildcard characters. This is the same as often found on Dos/Unix command lines.
For example, to retrieve and print all Java files that have the expression test in the name in the current directory:
FileSystemManager fsManager = VFS.getManager();
FileObject dir = fsManager.toFileObject(new File("."));
FileObject[] files;
files = dir.findFiles(new FileFilterSelector(new WildcardFileFilter("*test*.java")));
for (int i = 0; i < files.length; i++) {
System.out.println(files[i]);
}
