Class URLFileSystem.FileInfo

java.lang.Object

oracle.ide.net.URLFileSystem.FileInfo

Enclosing class:

URLFileSystem

public static class URLFileSystem.FileInfo
extends java.lang.Object

The FileInfo class encapsulates the information describing files returned by the URLFileSystem.ls(URL) and URLFileSystem.ls(URL, URLFilter) methods.

The information contained by each FileInfo object is current only as of the time the object was constructed. The underlying fields of the FileInfo object will contain out of date information if the underlying file system object is modified after the FileInfo object has been constructed.

Constructor Detail

FileInfo

public FileInfo(java.net.URL url)

Constructs a FileInfo object from the specified URL. The fields of the object are populated by querying the respective URLFileSystem methods for the given URL.

NOTE: This constructor exists merely for convenience, and should not be generally used, as it is the least performant way to construct a FileInfo object.
