Member Enumerations Documentation

Enum TMediaIdMatchType

Describes the type of media ID match to be performed on the plugins return from the ECOM registry.

Enumerators

ENoMediaIdMatch	No media ID match will be performed.
EAllowOtherMediaIds	All plugins that support the media ID supplied will be returned, even those that support other media IDs. For example, if an audio plugin is requested, plugins that support audio and video will also be returned.
EAllowOnlySuppliedMediaIds	Only plugins that support the exact media IDs supplied will be returned. For example, if an audio plugin is requested, plugins that only support audio will be returned (ie. no audio/video plugins).

Enum TPreferredSupplierMatchType

Describes the type of preferred supplier match to be performed on the plugins return from the ECOM registry.

Enumerators

ENoPreferredSupplierMatch	No preferred supplier match will be performed.
EPreferredSupplierPluginsFirstInList	Plugins from all suppliers will be returned, but those from the preferred supplier will be first in the list.
EOnlyPreferredSupplierPluginsReturned	Only plugins from the preferred supplier will be returned.
