Method Detail

contains

public boolean contains(S2Cell cell)

Only returns true if one of the regions fully contains the cell.

Specified by:

contains in interface S2Region

contains

public boolean contains(S2Point point)

Only returns true if one of the regions contains the point.

Specified by:

contains in interface S2Region

getCapBound

public S2Cap getCapBound()

Description copied from interface: S2Region

Return a bounding spherical cap.

Specified by:

getCapBound in interface S2Region

getRectBound

public S2LatLngRect getRectBound()

Description copied from interface: S2Region

Return a bounding latitude-longitude rectangle.

Specified by:

getRectBound in interface S2Region

mayIntersect

public boolean mayIntersect(S2Cell cell)

Returns true if the cell may intersect any region in this collection.

Specified by:

mayIntersect in interface S2Region

equals

public boolean equals(Object thatObject)

Returns true if this S2RegionUnion is equal to another S2RegionUnion, where each region must be equal and in the same order. This method is intended only for testing purposes. NOTE: This should be rewritten to disregard order if such functionality is ever required.
