Class S2RegionIntersection

java.lang.Object

com.google.common.geometry.S2RegionIntersection

All Implemented Interfaces:

S2Region, Serializable

@GwtCompatible(serializable=true)
public class S2RegionIntersection
extends Object
implements S2Region, Serializable

An S2RegionIntersection represents an intersection of overlapping regions. It is convenient for computing a covering of the intersection of a set of regions. The regions are assumed to be immutable. Note: An intersection of no regions covers the entire sphere.

Constructor Detail

S2RegionIntersection

public S2RegionIntersection(Collection<S2Region> regions)

Create an intersection from a copy of regions.

Method Detail

contains

public boolean contains(S2Cell cell)

Returns true if all the regions fully contain the cell.

Specified by:

contains in interface S2Region

contains

public boolean contains(S2Point point)

Returns true if all the regions fully contain 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 all regions in this collection.

Specified by:

mayIntersect in interface S2Region

equals

public boolean equals(Object thatObject)

Returns true if this S2RegionIntersection is equal to another S2RegionIntersection, 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.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
