Constructor details
BoundingBox
public BoundingBox(Coord c, double rLat, double rLng)Creates a bounding box around a coordinate with a given radius.
Parameters
cCoord- The coordinate at the center of the bounding box.
rLatdouble- The latitude radius of the box (in degrees).
rLngdouble- The longitude radius of the box (in degrees).
BoundingBox
public BoundingBox(Coord southWest, Coord northEast)Constructor with 2 coordinates for south west and north east
Parameters
southWestCoord- coordinate
northEastCoord- coordinate
Method details
create
public static BoundingBox create(Coord[] coords)create a smallest bounding box that contains all of the given coordinates
Parameters
coordsCoord[]- given coordinates to create a wrapping bounding box.
Returns
a bounding box that contains all of the coordinates
create
public static BoundingBox create(Vector coords)/**
create a smallest bounding box that contains all of the given coordinates
Parameters
coordsVector- given coordinates to create a wrapping bounding box.
Returns
a bounding box that contains all of the coordinates
getSouthWest
public Coord getSouthWest()Gets the /south west coordinate
getNorthEast
public Coord getNorthEast()Gets the north east coordinate
toString
public String toString()Returns a string representation of the object. In general, the toString method returns a string that “textually represents” this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@’, and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + ‘@’ + Integer.toHexString(hashCode())
latitudeDifference
public double latitudeDifference()Returns
The difference between SE and NW getLongitude in degrees.
longitudeDifference
public double longitudeDifference()Returns
The difference between SE and NW latitudes in degrees.
contains
public boolean contains(Coord cur)indicates if the given coordinate is inside the counding box
Parameters
curCoord- coordinate to check
Returns
true if the given coordinate is contained in the bounding box
equals
public boolean equals(Object other)Indicates whether some other object is “equal to” this one.
The equals method implements an equivalence relation: It is reflexive: for any reference value x, x.equals(x) should return true. It is symmetric: for any reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true. It is transitive: for any reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true. It is consistent: for any reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the object is modified. For any non-null reference value x, x.equals(null) should return false.
The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).
hashCode
public int hashCode()Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.
The general contract of hashCode is: Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result. It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
extend
public BoundingBox extend(BoundingBox other)create a new bounding box that extends this bounding box with the given
bounding box
Parameters
otherBoundingBox- a bounding box that needs to extends the current bounding box
Returns
a new bounding box that was extended from the current and the other
projected
public boolean projected()Indicates if this bounding box is isProjected
Returns
true if it’s a isProjected bounding box
