Method overview

Attributes

Methods

Clears the current history entry. This is used to clear out the saved presentation state.

void clearHistoryEntry();

Parameters

None.

close()

All users of a content viewer are responsible for calling both close() and destroy(), in that order.

close() should be called when the load of a new page for the next content viewer begins, and destroy() should be called when the next content viewer replaces this one.

void close(
  in nsISHEntry historyEntry
);

Parameters

historyEntry

The session history entry for the content viewer. If this is null, then destroy() will be called on the document by close(). If it is non-null, the document will not be destroyed, and the following actions will happen when destroy() is called:

• Sanitize() will be called on the viewer's document
• The content viewer will set the contentViewer property on the history entry, and release its reference (ownership reversal).
• Hide() will be called, and no further destruction will happen.
