Point center
 

Detailed Description

An abstract base class that represents a shape on a 2D plane. Its only member is "center" which maintains the center point of the shape. It has pure virtual methods for identifying the type of shape and calculating the shape's area that must be implemented by subclasses.

Constructor & Destructor Documentation

◆ Shape() [1/2]

Shape::Shape ( int  x,
int  y 
)

Overloaded constructor that takes in an (x,y) coordinate.

Parameters
xThe X coordinate of the shape's center point in 2D space
yThe Y coordinate of the shape's center point in 2D space

◆ Shape() [2/2]

Shape::Shape ( Point  c)

Overloaded constructor that takes in a center Point.

Parameters
cThe center point of the shape in 2D space

Member Function Documentation

◆ getArea()

virtual double Shape::getArea ( ) const
pure virtual

Pure virtual function for Shape subclasses. Subclasses overriding this method should use it to calculate the area of the shape and return the area as a floating point number.

Precondition
Valid data must be set on the Shape object
Postcondition
Does not change the object
Returns
A floating point number representing the area of the Shape

Implemented in Rectangle, Triangle, and Circle.

◆ getCenter()

Point Shape::getCenter ( ) const

Accessor for the shape's center point.

Precondition
None
Postcondition
Does not change the object
Returns
The current center point of the shape as a Point object.

◆ getType()

virtual std::string Shape::getType ( ) const
pure virtual

Pure virtual function for Shape subclasses. Returns a string indicating what type of shape this object is.

Precondition
None
Postcondition
Does not change the object
Returns
A string name of the current shape

Implemented in Rectangle, Triangle, and Circle.

◆ setCenter()

void Shape::setCenter ( Point  c)

Mutator for the shape's center point.

Precondition
None
Postcondition
The "center" member variable of Shape will be changed to the input value.
Parameters
cThe new center point for the Shape.
