Method Detail

cloneMutable

public Object cloneMutable()

Specified by:

cloneMutable in interface WriteCloneable

clone

public Object clone()

Overrides:

clone in class Object

compareTo

public int compareTo(PointImmutable d)

Description copied from interface: PointImmutable

Compares the square of the position.

Specified by:

compareTo in interface Comparable<PointImmutable>

Specified by:

compareTo in interface PointImmutable

equals

public boolean equals(Object obj)

Description copied from interface: PointImmutable

Checks whether two points objects are equal. Two instances of PointReadOnly are equal if the two components y and x are equal.

Specified by:

equals in interface PointImmutable

Overrides:

equals in class Object

Returns:

true if the two points are equal; otherwise false.

getX

public final int getX()

Specified by:

getX in interface PointImmutable

getY

public final int getY()

Specified by:

getY in interface PointImmutable

hashCode

public int hashCode()

Specified by:

hashCode in interface PointImmutable

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

set

public final void set(int x,
       int y)

setX

public final void setX(int x)

setY

public final void setY(int y)

translate

public final Point translate(Point pd)

Translate this instance's x- and y-components, i.e. add the values of the given delta point to them.

Parameters:

pd - delta point

Returns:

this instance for scaling

translate

public final Point translate(int dx,
              int dy)

Translate this instance's x- and y-components, i.e. add the given deltas to them.

Parameters:

dx - delta for x

dy - delta for y

Returns:

this instance for scaling

scale

public final Point scale(int sx,
          int sy)

Scale this instance's x- and y-components, i.e. multiply them by the given scale factors.

Parameters:

sx - scale factor for x

sy - scale factor for y

Returns:

this instance for scaling

scaleInv

public final Point scaleInv(int sx,
             int sy)

Inverse scale this instance's x- and y-components, i.e. divide them by the given scale factors.

Parameters:

sx - inverse scale factor for x

sy - inverse scale factor for y

Returns:

this instance for scaling
