Constructor Detail

ProductConstraint

public ProductConstraint(java.util.ArrayList<SketchPath> inPaths)

Product constraint constructor. Accepts an ArrayList that can have any number of paths. Gives default coordinates.

Parameters:

inPaths - An ArrayList of SketchPaths

ProductConstraint

public ProductConstraint(java.util.ArrayList<SketchPath> inPaths,
                         int x,
                         int y,
                         boolean isVisible)

Product constraint constructor. Accepts coordinates in constructor to allow for user-defined visual placement.

Parameters:

inPaths - An ArrayList of SketchPaths

x - X coordinate of visual on graph

y - Y coordinate of visual on graph

isVisible - If the constraint is visible in the graph or not

Method Detail

setPaths

public void setPaths(java.util.ArrayList<SketchPath> inPaths)

Sets the path array, updates edge list, and updates display

Parameters:

inPaths - The new array of paths

isProductConstraint

public static boolean isProductConstraint(java.util.ArrayList paths)

Method to determine whether a given set of paths could legally create a product constraint.

Parameters:

paths - The paths potentially involved in a product constraint

Returns:

True if a legal path configuration, false otherwise
