Constructor Detail

RectRegion

public RectRegion(Number minX,
                  Number maxX,
                  Number minY,
                  Number maxY,
                  String label)

Parameters:

minX -

maxX -

minY -

maxY -

RectRegion

public RectRegion(Number minX,
                  Number maxX,
                  Number minY,
                  Number maxY)

Method Detail

containsPoint

public boolean containsPoint(android.graphics.PointF point)

containsValue

public boolean containsValue(Number x,
                             Number y)

containsDomainValue

public boolean containsDomainValue(Number value)

containsRangeValue

public boolean containsRangeValue(Number value)

intersects

public boolean intersects(RectRegion region)

intersects

public boolean intersects(Number minX,
                          Number maxX,
                          Number minY,
                          Number maxY)

Tests whether this region intersects the region defined by params. Use null to represent infinity. Negative and positive infinity is implied by the boundary edge, ie. a maxX of null equals positive infinity while a minX of null equals negative infinity.

Parameters:

minX -

maxX -

minY -

maxY -

Returns:

intersects

public boolean intersects(android.graphics.RectF region,
                          Number visMinX,
                          Number visMaxX,
                          Number visMinY,
                          Number visMaxY)

getRectF

public android.graphics.RectF getRectF(android.graphics.RectF plotRect,
                                       Number visMinX,
                                       Number visMaxX,
                                       Number visMinY,
                                       Number visMaxY)

regionsWithin

public static List<RectRegion> regionsWithin(List<RectRegion> regions,
                                             Number minX,
                                             Number maxX,
                                             Number minY,
                                             Number maxY)

Returns a list of XYRegions that either completely or partially intersect the area defined by params. A null value for any parameter represents infinity / no boundary.
