public ContentHandlerFactory()

Method Detail

register

public static void register(ContentViewer handler)

Registers a viewer or editor with the factory. Before the factory is used, all needed editors and viewers should be registered (in that order). Order is important here because all editors are considered viewers by default. If a separate viewer is registered after an editor that handles the same type, that viewer will be the one provided via getViewer. In general, the last viewers/editors passed in will have the most precendence.

hasViewer

public static boolean hasViewer(java.lang.String type)

Can the factory provide a viewer for the given type?

viewerIsEditor

public static boolean viewerIsEditor(java.lang.String type)

If a viewer would be provided for the given type, is that viewer also an editor?

hasEditor

public static boolean hasEditor(java.lang.String type)

                               throws java.io.IOException
