- 17:09 Changeset [513] by
-
Fixed the problem that sometimes an operator link was not patched before a view was created (which resulted in a NullException) by adding a property for the source database in OperatorLink! and updating this property recursively whenever an operator is loaded from the CEDMA DB.
The method for recursively setting the property is in static class OperatorLinkPatcher because the code is needed in Agent, DatabaseOperatorLibrary and OperatorLink.

- GPOperatorGroup adds event-handlers to SubOperatorTypeConstraints on the operators added to the library to automatically update min tree size and height when any of them is changed.
(ticket #225)
- 23:33 Changeset [431] by
-
removed the 'AllowedSubOperators' variable for functions because the original intention was to cache the list of allowed sub-functions which is actually determined by a tree of constraints. However the original idea was never fully implemented so up to now any function in the library was allowed for any other function as long as it was not a terminal (also defined by constraints on the arity). The 'AllowedSubOperators' variable is not necessary at all when we defined the set via constraints. The SubOperatorsConstraintView allows draging of functions from the library into the constraint.
Next step: automatic adaption of SubOperatorsConstraints of functions in the library when new functions are added or existing entries removed.
