Method Detail

storeUserDefinedResolver

protected final void storeUserDefinedResolver(Map<String,Set<String>> mimeToExtensions)

Stores declarative resolver corresponding to specified mapping of MIME type and set of extensions. This resolver has the highest priority. Usually it resides in userdir/config/Servicer/MIMEResolver.

Not intended for use by modules outside the NetBeans Platform.

Parameters:

mimeToExtensions - mapping of MIME type to set of extensions like {image/jpeg=[jpg, jpeg], image/gif=[]}

getOrderedResolvers

protected final Collection<? extends FileObject> getOrderedResolvers()

Lists registered MIMEResolver instances in reverse order, i.e. first are ones with lower priority (position attribute higher) and last are ones with highest prority (position attribute lower).

Not intended for use by modules outside the NetBeans Platform.

Returns:

list of all registered MIME resolver definitions in reverse order

isUserDefined

protected final boolean isUserDefined(FileObject mimeResolverFO)

Checks whether a given resolver is user-defined.

Not intended for use by modules outside the NetBeans Platform.

Parameters:

mimeResolverFO - resolver definition

Returns:

true if the specified file is a user-defined MIME resolver, false otherwise

getMIMEToExtensions

protected final Map<String,Set<String>> getMIMEToExtensions(FileObject fo)

Returns mapping of MIME type to set of extensions.

Not intended for use by modules outside the NetBeans Platform.

Parameters:

fo - MIMEResolver definition

Returns:

mapping of MIME type to set of extensions like {image/jpeg=[jpg, jpeg], image/gif=[]} (never null but may be empty)
