      com.livescribe.geom.Stroke

public class Stroke
extends Shape

This class describes a stroke, or series of points. This is similar to a polyline but not the same because it contains other information such as time.

Constructor Detail

Stroke

public Stroke()

Creates a new stroke having no points.

The internal Shape.vertex array is set to null.

Stroke

public Stroke(int n)

Creates a new stroke having n points set to (0,0).

Parameters:

n - the number of points

Stroke

public Stroke(int[] v)

Parameters:

startTime - the absolute start time

index - the coordinate index

Returns:

the computed time.

getRelativeCoordinateTime

public long getRelativeCoordinateTime(long endTime,
                                      int index)

Gets the coordinate time in relation to the stroke's end time.

Parameters:

endTime - the end time

index - coordinate index

Returns:

the computed time.

getEndTime

public long getEndTime(long startTime)

Gets the stroke's end time.

Parameters:

startTime - the start time of the stroke

Returns:

the computed end time.

toString

public String toString()

Returns a string representation of this object.

Overrides:

toString in class Shape

Returns:

a string representation of this object.
