Class FileSystemElement

All Implemented Interfaces:

public class FileSystemElement extends Object implements 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.
