Method Detail

createPortConstraintFromSketch

public PortConstraint createPortConstraintFromSketch(LayoutGraph graph,
                                                     Edge edge,
                                                     boolean source,
                                                     boolean strong)

Creates a PortConstraint for the given edge. The side of the constraint is set up according to the current drawing of the edge within the given graph.

Parameters:

graph - the input graph

edge - the edge

source - true if a source PortConstraint for the given edge will be created, false for a target PortConstraint

strong - true if a strong PortConstraint is created, false for a weak PortConstraint

Returns:

the PortConstraint for the given edge whose side is retrieved from the initial drawing

createPortConstraintsFromSketch

public void createPortConstraintsFromSketch(LayoutGraph graph,
                                            EdgeMap spcMap,
                                            EdgeMap tpcMap)

Creates weak PortConstraints for all edges of the given graph.

Parameters:

graph - the input graph

spcMap - the EdgeMap that will be used for storing the source PortConstraints of the edges

tpcMap - the EdgeMap that will be used for storing the target PortConstraints of the edges

createPortConstraintsFromSketch

public void createPortConstraintsFromSketch(LayoutGraph graph,
                                            EdgeCursor ec,
                                            EdgeMap spcMap,
                                            boolean strongSP,
                                            EdgeMap tpcMap,
                                            boolean strongTP)

Creates PortConstraints for some edges of the given graph.

Parameters:

graph - the input graph

ec - the EdgeCursor that provides access to the edges for which to create PortConstraints

spcMap - the EdgeMap that will be used for storing the source PortConstraints of the edges

strongSP - true if strong source PortConstraints should be assigned, false otherwise

tpcMap - the EdgeMap that will be used for storing the target PortConstraints of the edges

strongTP - true if strong target PortConstraints should be assigned, false otherwise
