getLoc

public objects.Location getLoc()

Description copied from interface: Locatable

Returns the Location of this Locatable.

Specified by:

getLoc in interface Locatable

equals

public boolean equals(Object o)

Overrides:

equals in class Object

getDistance

public double getDistance(objects.Locatable other)

Description copied from interface: Locatable

Returns the distance on the unit square between this and loc.

Specified by:

getDistance in interface Locatable

public int hashCode()

Returns the hash code of this object. Note that this implementation will return the same hash code for two different locations if their x and y coordinates differ by less than the millionth siginficant digit.

Overrides:

hashCode in class Object

isEastOf

public boolean isEastOf(objects.Locatable other)

Description copied from interface: Locatable

Returns whether this Locatable is south of loc.

Specified by:

isEastOf in interface Locatable

isNorthOf

public boolean isNorthOf(objects.Locatable other)

Description copied from interface: Locatable

Returns whether this Locatable is north of loc.

Specified by:

isNorthOf in interface Locatable

isSouthOf

public boolean isSouthOf(objects.Locatable other)

Description copied from interface: Locatable

Returns whether this Locatable is east of loc.

public boolean isWestOf(objects.Locatable other)

Description copied from interface: Locatable

Returns whether this Locatable is west of loc.

Specified by:

isWestOf in interface Locatable

toString

public String toString()

Overrides:

toString in class Object
