FileSystemEntry: isDirectory property
The read-only isDirectory
property of the FileSystemEntry interface is true if the
entry represents a directory (meaning it's a FileSystemDirectoryEntry)
and false if it's not.
You can also use isFile to determine if the
entry is a file.
Warning:
You should not assume that any entry which isn't a directory is a file or vice versa.
There are other types of file descriptors on many operating systems. Be sure to use
both isDirectory and isFile as needed to ensure that the
entry is something you know how to work with.
Value
A Boolean indicating whether or not the FileSystemEntry is a directory.
Examples
This example shows how this property might be used to determine whether to process the entry as a directory or file. If the entry is neither, an error handler is called with an appropriate message.
if (entry.isDirectory) {
processSubdirectory(entry);
} else if (entry.isFile) {
processFile(entry);
} else {
displayErrorMessage("Unsupported file system entry specified.");
}
