AUTO_LINK is a parameter of the structure proxy's constructor method. When the parameter AUTO_LINK = GFW_TRUE the graphics proxy automatically generates links from the nodes in the data container.

Using the AUTO_LINK function improves performance.

You can only use this function with hierarchy graphics. For network graphics AUTO_LINK must be set to GFW_FALSE.


The parameter AUTO_LINK must be set to GFW_TRUE. If it is set to GFW_FALSE then the links have to be maintained in the data container as usual. In the latter case the nodes and links are independent objects in the data container.


The nodes define the links between each other using the attributes SUCC and PRED.
