Class StrokeStorage

java.lang.Object
  com.livescribe.storage.StrokeStorage

public class StrokeStorage
extends Object

This class describes the system stroke storage. It gives information about current, previous, and next strokes based on time values.

The current implementation is limited to querying the last 50 strokes obtained by the system. For example, if you have a timestamp from before the last 50 strokes, then this will not be able to find that stroke.

Constructor Summary

StrokeStorage(PageInstance page)
Creates a new stroke storage instance.

Method Summary

Point	getLastCoord() Returns the last point.
long	getLastStroke() Returns the last stroke time.
long	getNextStroke(long time) Returns the next stroke time, in milliseconds.
long	getPreviousStroke(long time) Returns the previous stroke time, in milliseconds.
Stroke	getStroke(long time) Returns the stroke corresponding to the specified time.
Rectangle	getStrokeBoundingBox(long time) Returns the rectangle bounding the stroke.
boolean	isTap(long time) Checks if the stroke is a tap
boolean	isTap(long time1, long time2) Checks if a stroke is a double tap

getStrokeBoundingBox

public Rectangle getStrokeBoundingBox(long time)

Returns the rectangle bounding the stroke.

Parameters:

time - the time corresponding to the stroke

Returns:

the rectangle bounding the stroke.

getPreviousStroke

public long getPreviousStroke(long time)

Returns the previous stroke time, in milliseconds.

Parameters:

time - the time corresponding to the current stroke

Returns:

previous stroke time, in ms.

getNextStroke

public long getNextStroke(long time)

Returns the next stroke time, in milliseconds.

Parameters:

time - the time corresponding to the current stroke

Returns:

next stroke time, in ms.

getLastStroke

public long getLastStroke()

Returns the last stroke time.

Returns:

the time of the last stroke, in ms.

getLastCoord()

isTap

public boolean isTap(long time)

Checks if the stroke is a tap

Parameters:

time - the timestamp of the stroke

Returns:

true if it is a tap, false if stroke is not found or it is not a tap

isTap

public boolean isTap(long time1,
                     long time2)

Checks if a stroke is a double tap

Parameters:

time1 - the timestamp of one of the strokes

time2 - the timestamp of the other stroke (order does not matter)

Returns:

if it is a double tap, false if stroke is not found or it is not a double tap

getLastCoord

public Point getLastCoord()

Returns the last point. This will return an instance of Point. This can be used, for example, in a thread that monitors the current pen position.

Returns:

the last coordinate as a Point instance.
