Function Usage

Returns the next match result that conforms to the pattern definition, following the topological order of the current target graph.

This one-by-one matching API allows you to resolve selection issues in overlap scenarios. The API can be called iteratively in a loop.

Note:

• The match results returned by the current API may overlap. The caller needs to process the results.

  In the following structure, C appears in two match results in sequence during ABC matching. The caller needs to determine which result to select.

           B  C   B
           \ / \ /
            A   A

• This function matches only the current graph. If the target graph contains subgraphs, the caller needs to match the subgraphs.
