Constructor Detail

Point

public Point()

Constructor for Point.

Point

public Point(int x,
             int y)

Constructor for Point.

Point

public Point(ReadablePoint p)

Constructor for Point.

Method Detail

setLocation

public void setLocation(int x,
                        int y)

Specified by:

setLocation in interface WritablePoint

setLocation

public void setLocation(ReadablePoint p)

Specified by:

setLocation in interface WritablePoint

setX

public void setX(int x)

Specified by:

setX in interface WritablePoint

setY

public void setY(int y)

Specified by:

setY in interface WritablePoint

translate

public void translate(int dx,
                      int dy)

Translate a point.

Parameters:

dx - The translation to apply

dy - The translation to apply

translate

public void translate(ReadablePoint p)

Translate a point.

Parameters:

p - The translation to apply

untranslate

public void untranslate(ReadablePoint p)

Un-translate a point.

Parameters:

p - The translation to apply

equals

public boolean equals(java.lang.Object obj)

Determines whether an instance of Point2D is equal to this point. Two instances of Point2D are equal if the values of their x and y member fields, representing their position in the coordinate space, are the same.

Overrides:

equals in class java.lang.Object

Parameters:

obj - an object to be compared with this point

Returns:

true if the object to be compared is an instance of Point and has the same values; false otherwise

toString

public java.lang.String toString()

Returns a string representation of this point and its location in the (x, y) coordinate space. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Overrides:

toString in class java.lang.Object

Returns:

a string representation of this point

hashCode

public int hashCode()

Returns the hash code for this Point.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code for this Point

getX

public int getX()

Specified by:

getX in interface ReadablePoint

Returns:

int

getY

public int getY()

Specified by:

getY in interface ReadablePoint

Returns:

int

getLocation

public void getLocation(WritablePoint dest)

Description copied from interface: ReadablePoint

Copy this ReadablePoint into a destination Point

Specified by:

getLocation in interface ReadablePoint

Parameters:

dest - The destination Point, or null, to create a new Point
