Method Detail

isSimpleConcatenation

public static boolean isSimpleConcatenation(Regexp<AbstractStructuralNode> r)

Returns flag if the provided regexp is a simple concatenation. Regexp is a simple concatenation if all these conditions hold:

• Its type is RegexpType.CONCATENATION.
• Its interval is "once" (RegexpInterval.isOnce()).
• For each of its children holds:
