Method	Description

center	Returncs coordinates of center of the rectangle.
clone	Clones the Rectangle object.
compareTo	CompareTo
contains	Determinces whether given point is inside of the rectangle.
contains	Determinces whether given point is inside of the rectangle.

getTrivial	Initializes trivial rectangle i.e. rectangle with zero position and size.
getURX	Gets X - coordinate of upper-right corner.
getURY	Gets Y - coordinate of upper-right corner.
getWidth	Gets width of rectangle.
hashCode	Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by {@link java.util.HashMap}. The general contract of {@code hashCode} is: Whenever it is invoked on the same object more than once during an execution of a Java application, the {@code hashCode} method must consistently return the same integer, provided no information used in {@code 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 {@code equals(Object)} method, then calling the {@code 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 {@link java.lang.Object#equals(java.lang.Object)} method, then calling the {@code 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 hash tables. As much as is reasonably practical, the hashCode method defined by class {@code 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 Java^TM programming language.)
intersect	Intersects to rectangles.
isEmpty	Checks if rectangle is empty.
isInclude	Checks that this rectangle includes whole another rectangle. I.e. whole another rectangle is inside this rectangle. Difference with IsIntersect method is that IsIntersect will true for partly intersected rectangles but IsInclude will false.
isIntersect	Determines whether this rectangle intersects with other rectangle.
isPoint	Checks if rectangle is point i.e. LLX is equal URX and LLY is equal URY.
isTrivial	Checks if rectangle is trivial i.e. has zero size and position.
join	Joins rectangles.

rotateAngle	Rotate rectangle by the specified angle.
setLLX	Sets X-coordinate of lower - left corner.
setLLY	Sets Y - coordinate of lower-left corner.
setURX	Sets X - coordinate of upper-right corner.
setURY	Sets Y - coordinate of upper-right corner.

toPoints	Converts rectangle into array of points (“QuadPoints”).

hashCode

public int hashCode()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by {@link java.util.HashMap}.

The general contract of {@code hashCode} is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the {@code hashCode} method must consistently return the same integer, provided no information used in {@code 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 {@code equals(Object)} method, then calling the {@code 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 {@link java.lang.Object#equals(java.lang.Object)} method, then calling the {@code 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 hash tables.

As much as is reasonably practical, the hashCode method defined by class {@code 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 Java^TM programming language.)

Returns: a hash code value for this object. @see java.lang.Object#equals(java.lang.Object) @see java.lang.System#identityHashCode
