public final Class LayoutPathImpl.SegmentPath

Class Inheritance

extends LayoutPathImpl

Represents a path built from segments. Each segment is represented by a triple: x, y, and cumulative advance. These represent the end point of the segment. The start point of the first segment is represented by the triple at position 0. The path might have breaks in it, e.g. it is not connected. These will be represented by pairs of triplets that share the same advance. The path might be extended, pinned, or closed. If extended, the initial and final segments are considered to extend 'indefinitely' past the bounds of the advance. If pinned, they end at the bounds of the advance. If closed, advances before the start or after the end 'wrap around' the path. The start of the path is the initial triple. This provides the nominal advance at the given x, y position (typically zero). The end of the path is the final triple. This provides the advance at the end, the total length of the path is thus the ending advance minus the starting advance.

Note

We might want to cache more auxiliary data than the advance, but this seems adequate for now.

getSegmentIndexForAdvance

back to summary

private int getSegmentIndexForAdvance(double a, boolean preceding)

Return the index of the segment associated with advance. This points to the start of the triple and is a multiple of 3 between 3 and data.length-3 inclusive. It never points to a 'moveto' triple. If the path is closed, 'a' is mapped to a value between the start and end of the path, inclusive. If preceding is true, and 'a' lies on a segment boundary, return the index of the preceding segment, else return the index of the current segment (if it is not a moveto segment) otherwise the following segment (which is never a moveto segment).

Note

if the path is not closed, the advance might not actually lie on the returned segment-- it might be before the first, or after the last. The first or last segment (as appropriate) will be returned in this case.

complete	back to summary
public LayoutPathImpl.SegmentPath complete(LayoutPathImpl.EndType etype) Complete building a SegmentPath. Once this is called, the builder is restored to its initial state and information about the previous path is released. The end type indicates whether to treat the path as closed, extended, or pinned.

lineTo	back to summary
public void lineTo(double x, double y) Connect to a new point. If there is no data, the previous point is presumed to be 0, 0. This point is checked against the previous point, and if different, this point is added to the path and the advance extended. If this point is the same as the previous point, the path remains unchanged.

moveTo

back to summary

public void moveTo(double x, double y)

Move to a new point. If there is no data, this will become the first point. If there is data, and the previous call was a lineTo, this point is checked against the previous point, and if different, this starts a new segment at the same advance as the end of the last segment. If there is data, and the previous call was a moveTo, this replaces the point used for that previous call. Calling this is optional, lineTo will suffice and the initial point will be set to 0, 0.

nextPoint	back to summary
private void nextPoint(double x, double y, boolean connect) Add a new point, and increment advance if connect is true. This automatically rejects duplicate points and multiple disconnected points.

reset	back to summary
public void reset(int datalen) Reset the builder for a new path. Datalen is a hint of how many points will be in the path, and the working buffer will be sized to accommodate at least this number of points. If datalen is zero, the working buffer is freed (it will be allocated on first use).
