Method Details
-
create
Returns a property conduit instance for the given expression. PropertyConduitSource caches the conduits it returns, so despite the name, this method does not always create a new conduit. The cache is cleared if a change to component classes is observed. Callers of this method should observe notifications from theInvalidationEventHub
forComponentClasses
and discard any aquired conduits; failure to do so will create memory leaks whenever component classes change (the conduits will keep references to the old classes and classloaders).- Parameters:
rootType
- the type of the root object to which the expression is appliedexpression
- expression to be evaluated on instances of the root class- Returns:
- RuntimeException if the expression is invalid (poorly formed, references non-existent properties, etc.)
