When I run my multiple inheritance pattern, I expected only one match but there are two different matches. When I specify the pattern cardinality of child classes as 2..* and the pattern cardinality of parent classes as 1, I expect one parent class and at least two child class in one match. If there
is a second multiple inheritance case in the model, it will return in the second match. And in my case when the number of the child classes which are inherited from the same class increases, I expect the number of the matches not to increase but it also increases.</DIV> <DIV>Am I missing something?<BR><BR><B><I>Attila Vizhanyo <viza@isis.vanderbilt.edu></I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">The pattern cardinality attribute of pattern objects in GReAT has the <BR>following semantics:<BR>- the cardinality attribute set to 0 means negative application <BR>condition, that is, the pattern matching returns true, if the specified <BR>pattern could not be found in the input graph.<BR>- any other value than 0 corresponds to 'positive' application <BR>condition, with no regard to pattern cardinality.
