Enumeration Type Documentation

enum IlvLayoutReportType

This enumeration defines values used to indicate the status and behavior of the layout algorithm.

Enumerator:

IlvLayoutReportInitialCode	The initial value of the code. The method IlvGraphLayoutReport::getCode() returns this value if you have never set a different code using IlvGraphLayoutReport::setCode(IlvLayoutReportType).
IlvLayoutReportLayoutDone	The layout was performed normally.
IlvLayoutReportNotNeeded	The layout was not performed because there was no significant change in the graph since the last time the layout was performed successfully. This normally means that there was no change in topology (no nodes and no links were added or removed), no change in position (no nodes and no links were moved), and no change in parameter values.
IlvLayoutReportEmptyGrapher	The layout was not performed because the graph is empty.
IlvLayoutReportNoMoveableNode	The layout was not performed because there are no moveable nodes (all nodes are fixed). This may occur only if the subclass of IlvGraphLayout supports the preservation of fixed nodes and the method IlvGraphLayout::setPreserveFixedNodes(IlBoolean) has been called with an IlTrue argument. See also: IlvGraphLayout::supportsPreserveFixedLinks().
IlvLayoutReportNoReshapeableLink	The layout was not performed because there are no reshapeable links (all links are fixed). This may only occur if the subclass of IlvGraphLayout supports the preservation of fixed links and the method IlvGraphLayout::setPreserveFixedLinks(IlBoolean) has been called with an IlTrue argument. See also: IlvGraphLayout::supportsPreserveFixedLinks().
IlvLayoutReportLayoutStarted	The layout was started.
IlvLayoutReportLayoutFinished	The layout was finished.
IlvLayoutReportGreatestCode	The greatest integer value used as a code. You can use the value IlvLayoutReportGreatestCode+1 for the definition of a new code.
