A class factory allows the creation of nsISupports derived
components without specifying a concrete base class.
Creates an instance of a component.
aOuter | Pointer to a component that wishes to be aggregated in the resulting instance. This will be nullptr if no aggregation is requested. |
iid | The IID of the interface being requested in the component which is being currently created. |
result | [out] Pointer to the newly created instance, if successful. @throws NS_NOINTERFACE - Interface not accessible. @throws NS_ERROR_NO_AGGREGATION - if an 'outer' object is supplied, but the component is not aggregatable. NS_ERROR* - Method failure. |
LockFactory provides the client a way to keep the component
in memory until it is finished with it. The client can call
LockFactory(PR_TRUE) to lock the factory and LockFactory(PR_FALSE)
to release the factory.
lock | - Must be PR_TRUE or PR_FALSE @throws NS_ERROR* - Method failure. |
