Package org.eclipse.ui.dialogs
Class FileSystemElement
java.lang.Object
org.eclipse.ui.dialogs.FileSystemElement
- All Implemented Interfaces:
IAdaptable
Instances of this class represent files or file-like entities (eg.- zip file
entries) on the local file system. They do not represent resources within the
workbench. This distinction is made because the representation of a file
system resource is significantly different from that of a workbench resource.
If self represents a collection (eg.- file system directory, zip directory)
then its icon will be the folderIcon static field. Otherwise (ie.- self
represents a file system file) self's icon is stored in field "icon", and is
determined by the extension of the file that self represents.
This class is adaptable, and implements one adapter itself, namely the
IWorkbenchAdapter adapter used for navigation and display in the workbench.
