Constructor Detail

NFEInteractionEngine

public NFEInteractionEngine(NFEModel model)

Creates a new interaction engine instance

Parameters:

model - the current NFE model

Method Detail

findIntersections

public java.util.List<Intersection<NFEFeatureElement>> findIntersections(NFEFeatureElement tgrFeatElem,
                                                                         java.util.Collection<NFEFeatureElement> ignoredFeatElems,
                                                                         double tolerance)

Retrieves all the intersections of the given Feature Element. If the passed Feature Element is a point, the resulting list will contain only one intersection of two or more feature elements. If the passed Feature Element is a line, the resulting list will contain all the intersection points sorted from first to end line point.

Parameters:

tgrFeatElem - The target Feature Element. All the intersections with this Feature Element will be retrieved

ignoredFeatElems - Elements in this list will be ignored when interacting with the main Feature Element

tolerance - tolerance used to determine if two points can be considered the same

Returns:

findIntersections

public java.util.List<Intersection<NFEFeatureElement>> findIntersections(NFEFeatureElement tgrFeatElem,
                                                                         JGeometry tgrGeom,
                                                                         java.util.Collection<NFEFeatureElement> ignoredFeatElems,
                                                                         double tolerance)

Retrieves all the intersections of the given Feature Element, supposing the given geometry is the feature element's geometry. If the passed Feature Element is a point, the resulting list will contain only one intersection of two or more feature elements. If the passed Feature Element is a line, the resulting list will contain all the intersection points sorted from first to end line point.

Parameters:

tgrFeatElem - The target Feature Element. All the intersections with this Feature Element will be retrieved

tgrGeom - the feature element's geometry. It does not have to be the actual feature element's geometry but it has to be a suitable type for the feature element, that is, a line feature element requires a line geometry and so on.

ignoredFeatElems - Elements in this list will be ignored when interacting with the main Feature Element

tolerance - tolerance used to determine if two points can be considered the same

Returns:

addConnectableHierarchies

public void addConnectableHierarchies(int[] connHierarchies)

Sets which hierarchy levels allows inter-hierarchy interactions, that is, interactions between members of different hierarchies

Parameters:

connHierarchies - an array of hierarchy levels

removeConnectableHierarchies

public void removeConnectableHierarchies(int[] connHierarchies)

Removes hierarchy levels for inter-hierarchy interactions

Parameters:

connHierarchies - an array of hierarchy levels

clearConnectableHierarchies

public void clearConnectableHierarchies()

Removes all the hierarchy levels for inter-hierarchy interactions.
