Class Point

java.lang.Object

org.eclipse.swt.graphics.Point

All Implemented Interfaces:

java.io.Serializable, SerializableCompatibility

public final class Point
extends java.lang.Object
implements SerializableCompatibility

Instances of this class represent places on the (x, y) coordinate plane.

The coordinate space for rectangles and points is considered to have increasing values downward and to the right from its origin making this the normal, computer graphics oriented notion of (x, y) coordinates rather than the strict mathematical one.

The hashCode() method in this class uses the values of the public fields to compute the hash value. When storing instances of the class in hashed collections, do not modify these fields after the object has been inserted.

Application code does not need to explicitly release the resources managed by each instance when those instances are no longer required, and thus no dispose() method is provided.

Constructor Detail

Point

public Point(int x,
     int y)

Constructs a new point with the given x and y coordinates.

Parameters:

x - the x coordinate of the new point

y - the y coordinate of the new point

Method Detail

equals

public boolean equals(java.lang.Object object)

Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison.

Overrides:

equals in class java.lang.Object

Parameters:

object - the object to compare with this object

Returns:

true if the object is the same as this object and false otherwise

See Also:

hashCode()

hashCode

public int hashCode()

Returns an integer hash code for the receiver. Any two objects that return true when passed to equals must return the same value for this method.

Overrides:

hashCode in class java.lang.Object

Returns:

the receiver's hash

equals(Object)

toString

public java.lang.String toString()

Returns a string containing a concise, human-readable description of the receiver.

Overrides:

toString in class java.lang.Object

Returns:

a string representation of the point
