void nsIFactory::createInstance ( in nsISupports  aOuter,
in nsIIDRef  iid,
[retval, iid_is(iid)] out nsQIResult  result 
) [inherited]

Creates an instance of a component.

aOuterPointer to a component that wishes to be aggregated in the resulting instance. This will be nsnull if no aggregation is requested.
iidThe IID of the interface being requested in the component which is being currently created.
result[out] Pointer to the newly created instance, if successful.
NS_OK - Component successfully created and the interface being requested was successfully returned in result. NS_NOINTERFACE - Interface not accessible. NS_ERROR_NO_AGGREGATION - if an 'outer' object is supplied, but the component is not aggregatable. NS_ERROR* - Method failure.

Here is the call graph for this function:

void nsIFactory::lockFactory ( in PRBool  lock) [inherited]

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
NS_OK - If the lock operation was successful. NS_ERROR* - Method failure.

    printf("nsTestComFactory: ");
    printf("%s", (aLock == PR_TRUE ? "Locking server" : "Unlocking server"));
    return S_OK;
