VisibleRegion

public class VisibleRegion extends Object
implements Serializable

An immutable trapezoid describing the area on the map that is visible from a specific camera position. When the camera is looking straight down, the visible region is rectangular (but not necessarily axis-aligned since the bearing may not be north). When the camera is tilted, the visible region is a trapezoid with the smaller of the two parallel sides closest to the camera.

Field Summary

public final LatLng	farLeft	Projection of the top left corner of the screen onto the ground plane.
public final LatLng	farRight	Projection of the top right corner of the screen onto the ground plane.
public final LatLngBounds	latLngBounds	The smallest bounding box that includes this visible region.
public final LatLng	nearLeft	Projection of the bottom left corner of the screen onto the ground plane.
public final LatLng	nearRight	Projection of the bottom right corner of the screen onto the ground plane.

Public Constructor Summary

VisibleRegion(LatLng nearLeft, LatLng nearRight, LatLng farLeft, LatLng farRight, LatLngBounds latLngBounds) Creates a new VisibleRegion given the four corners of the camera.

Fields

public final LatLng farLeft

Projection of the top left corner of the screen onto the ground plane.

public final LatLng farRight

Projection of the top right corner of the screen onto the ground plane.

public final LatLngBounds latLngBounds

The smallest bounding box that includes this visible region.

If this box crosses the 180° meridian (the vertical line from north to south), the longitude in farRight will be negative and the longitude in farLeft will be positive. This rule also applies to nearRight and nearLeft.

public final LatLng nearLeft

Projection of the bottom left corner of the screen onto the ground plane.

public final LatLng nearRight

Projection of the bottom right corner of the screen onto the ground plane.

Public Constructors

public VisibleRegion (LatLng nearLeft, LatLng nearRight, LatLng farLeft, LatLng farRight, LatLngBounds latLngBounds)

Creates a new VisibleRegion given the four corners of the camera. The LatLng parameters must define a convex shape (the edges of the resulting shape mustn't cross). No bounds checking is performed at runtime.

Parameters

nearLeft	a LatLng object containing the latitude and longitude of the near left corner of the region
nearRight	a LatLng object containing the latitude and longitude of the near right corner of the region
farLeft	a LatLng object containing the latitude and longitude of the far left corner of the region
farRight	a LatLng object containing the latitude and longitude of the far right corner of the region
latLngBounds	the smallest bounding box that includes the visible region defined in this class. If this box crosses the 180° meridian (the vertical line from north to south), the longitude in farRight will be negative and the longitude in farLeft will be positive. Same applies to nearRight and nearLeft.

Public Methods

public boolean equals (Object o)

Compares this VisibleRegion to another object. If the other object is actually a pointer to this object, or if all four corners and the bounds of the two objects are the same, this method returns true. Otherwise, this method returns false.

Parameters

o	an Object. Return true if both objects are the same object, or if all four corners and the bounds of the two objects are the same. Return false otherwise.
