This interface is implemented by the following components:

Constants

Returned by isTypeSupported to indicate lack of support for a type.
PRUint32 UNSUPPORTED = 0
Returned by isTypeSupported to indicate that a type is supported as an image.
PRUint32 IMAGE = 1
Returned by isTypeSupported to indicate that a type is supported via an NPAPI ("Netscape 4 API") plug-in. This is not the value returned for "XPCOM plug-ins".
PRUint32 PLUGIN = 2
Returned by isTypeSupported to indicate that a type is supported via some other means.
PRUint32 OTHER = 32768

Methods

PRUint32 isTypeSupported ( ACString type , nsIWebNavigation webNav )

PRUint32 isTypeSupported ( ACString type , nsIWebNavigation webNav )

Query whether type is supported.

Arguments:
type: the MIME type in question.
webNav: the nsIWebNavigation object for which the request is being made. This is allowed to be null. If it is non-null, the return value of this method may depend on the exact state of webNav and the values set through nsIWebBrowserSetup; otherwise the method will assume that the caller is interested in information about nsIWebNavigation objects in their default state.
Returns:
an enum value indicating whether and how aType is supported.
