end

#remove_condition(type, attributes) ⇒ Object

This method removes a condition. -1 means that the condition must be removed. 1 means that the condition given its attributes wasn’t found. The other case is that the condition was changed in another place, for example could have been removed in the intersectionSearchType called.

end

#replace_condition(type, attributes, new_condition) ⇒ Object

This method replaces a condition for a new condition. -1 means that the condition must be replaced. 1 means that the old condition in this case wasn’t found so that the old condition won’t be replaced. The other case is that the condition was changed in another place, for example could have been replaced in the intersectionSearchType called.
