Method Detail

getX

public float getX()

getY

public float getY()

negate

public FPoint negate()

Returns:

the negative point (x, y) => (-x, -y)

offset

public FPoint offset(float dx,
                     float dy)

Parameters:

dx - the x-axis offset

dy - the y-axis offset

Returns:

a point with the provided offsets

equals

public final boolean equals(float x,
                            float y)

Returns true if the point's coordinates equal (x,y)

Parameters:

x - the x value of the point that we want to compare

y - the y value of the point that we want to compare

Returns:

true if they are equal

equals

public boolean equals(Object o)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

length

public final float length()

Return the euclidian distance from (0,0) to this point

Returns:

the euclidian distance from (0,0) to this point

length

public static float length(float x,
                           float y)

Returns the euclidian distance from (0,0) to (x,y)

Parameters:

x - the x value on which to compute the distance

y - the y value on which to compute the distance

Returns:

the the euclidian distance from (0,0) to (x,y)
