Method Detail

getDistance

public double getDistance(double x,
                          double y,
                          double z)

                         double range)

isInRange

public boolean isInRange(double x,
                         double y,
                         double z,
                         double range)

copy

public Point copy(Point p)

plus

public Point plus(double val)

minus

public Point minus(double val)

isEqual

public boolean isEqual(Point p)

Utility method, confirms that coordinates of this point match the coordinates of the other point. Method equals() can't be used for that purpose as it includes object id - requirement for persistence.

Parameters:

p - Point to compare

Returns:

true if all coordinates are equal

getX

public double getX()

getY

public double getY()

getZ

public double getZ()

setX

public void setX(double x)

setY

public void setY(double y)

setZ

public void setZ(double z)

equals

public boolean equals(Object o)

Overrides:

equals in class Entity

canEqual

protected boolean canEqual(Object other)

Overrides:

canEqual in class Entity

hashCode

public int hashCode()

Overrides:

hashCode in class Entity

toString

public String toString()

Overrides:

toString in class Entity
