create
public PropertyConduit create(java.lang.Class rootClass, java.lang.String expression)
Description copied from interface:PropertyConduitSourceReturns 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 theInvalidationEventHubforComponentClassesand 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).- Specified by:
createin interfacePropertyConduitSource- Parameters:
rootClass- 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.)
-
nullTerm
public static java.lang.NullPointerException nullTerm(java.lang.String term, java.lang.String expression, java.lang.Object root)
May be invoked from fabricated PropertyConduit instances.
