  • Constructor Details

    • SegmentIteratorImpl

      public SegmentIteratorImpl(MultiPathImpl parent)

    • SegmentIteratorImpl

      public SegmentIteratorImpl(MultiPathImpl parent, int pointIndex)

    • SegmentIteratorImpl

      public SegmentIteratorImpl(MultiPathImpl parent, int pathIndex, int segmentIndex)

  • Method Details

    • resetTo

      void resetTo(SegmentIteratorImpl src)

    • nextCurve

      public Segment nextCurve()
      Moves the iterator to the next curve segment and returns the segment. The Segment is returned by value and is owned by the iterator. Note: The method can return null if there are no curves in the part.

    • nextSegment

      public Segment nextSegment()
      Moves the iterator to next segment and returns the segment. The Segment is returned by value and is owned by the iterator.

    • previousSegment

      public Segment previousSegment()
      Moves the iterator to previous segment and returns the segment. The Segment is returned by value and is owned by the iterator.

    • resetToFirstSegment

      public void resetToFirstSegment()
      Resets the iterator so that the call to NextSegment will return the first segment of the current path.

    • resetToLastSegment

      public void resetToLastSegment()
      Resets the iterator so that the call to PreviousSegment will return the last segment of the current path.

    • resetToVertex

      public void resetToVertex(int vertexIndex)

    • resetToVertex

      public void resetToVertex(int vertexIndex, int _pathIndex)

    • nextPath

      public boolean nextPath()
      Moves the iterator to next path and returns true if successful.

    • previousPath

      public boolean previousPath()
      Moves the iterator to next path and returns true if successful.

    • resetToFirstPath

      public void resetToFirstPath()
      Resets the iterator such that the subsequent call to the NextPath will set the iterator to the first segment of the first path.

    • resetToLastPath

      public void resetToLastPath()
      Resets the iterator such that the subsequent call to the PreviousPath will set the iterator to the last segment of the last path.

    • resetToPath

      public void resetToPath(int pathIndex)
      Resets the iterator such that the subsequent call to the NextPath will set the iterator to the first segment of the given path. The call to PreviousPath will reset the iterator to the last segment of path pathIndex - 1.

    • _getSegmentCount

      public int _getSegmentCount(int pathIndex)

    • isClosingSegment

      public boolean isClosingSegment()
      Returns True, if the segment is the closing segment of the closed path

    • setCirculator

      public void setCirculator(boolean bYesNo)
      Switches the iterator navigation mode.
      Parameters:
      bYesNo - If True, the iterator loops over the current path infinitely (unless the MultiPath is empty).

    • getPathIndex

      public int getPathIndex()
      Returns the index of the current path.

    • getStartPointIndex

      public int getStartPointIndex()
      Returns the index of the start Point of the current Segment.

    • _getPathBegin

      public int _getPathBegin()

    • getEndPointIndex

      public int getEndPointIndex()
      Returns the index of the end Point of the current Segment.

    • isFirstSegmentInPath

      public boolean isFirstSegmentInPath()
      Returns True if the segment is first one in the current Path.

    • isLastSegmentInPath

      public boolean isLastSegmentInPath()
      Returns True if the segment is last one in the current Path.

    • hasNextSegment

      public boolean hasNextSegment()
      Returns True if the call to the NextSegment will succeed.

    • hasPreviousSegment

      public boolean hasPreviousSegment()
      Returns True if the call to the NextSegment will succeed.

    • copy

      public SegmentIteratorImpl copy()

    • _updateSegment

      public void _updateSegment()

    • isLastPath

      boolean isLastPath()
