void TAO_Notify_Constraint_Interpreter::build_tree (  const char *constraints  ACE_ENV_ARG_DECL  )  throw (CosNotifyFilter::InvalidConstraint, CORBA::NO_MEMORY)
 

This method builds an expression tree representing the constraint specified in , and throws an Illegal Constraint exception if the constraint given has syntax errors or semantic errors, such as mismatched types.
