Class MutablePath

  • All Implemented Interfaces:
    Shape 

    public class MutablePath
extends AbstractShape
    A shape that lets you modify individual segments.

    This shape has the notion of several distinct paths where each path begins with a separator moveoTo() instruction. There are some methods that treat this object as one long string of segments, and some methods that recognize that you can access each path separately.

    Several methods here match the signatures of GeneralPath methods for convenience. Internally field and methods are made private/final because of the thorough verification that happens as you manipulate this object: subclasses shouldn't let you position anything other than a SEG_MOVETO after a SEG_CLOSE, for example.

        Redefine a segment. This lets you do anything without an exception: you could technically make a path begin a SEG_CLOSE, or place ten SEG_MOVETOs next to each other.
        Parameters:
        index -
        type -
        coords -
