class Integer2D

Defined in: TSInteger.h

The Integer2D class encapsulates a vector containing a pair of integer coordinates.

Definition

class Integer2D : public Vec2D<TypeInteger2D>

Member Functions

Integer2D::Set Sets both components of a vector.

Constructor

Integer2D();

Integer2D(int32 i, int32 j);

template <typename type> Integer2D(const Vec2D<type>& u);

Parameters

`i`	The value of the x coordinate.
`j`	The value of the y coordinate.
`u`	Another 2D vector, possibly with a different component type, that is converted to an `Integer2D`.

Description

The Integer2D class is used to store a vector having two integer components x and y.

The default constructor leaves the components of the vector undefined. If the values i and j are supplied, then they are assigned to the x and y coordinates of the vector, respectively.

Overloaded Operators

`int32& operator [](machine k);`	Returns a reference to the `k`-th scalar component of a vector. The value of `k` must be 0 or 1.
`const int32& operator [](machine k) const;`	Returns a constant reference to the `k`-th scalar component of a vector. The value of `k` must be 0 or 1.
`Integer2D& operator +=(const Integer2D& v);`	Adds the vector `v`.
`Integer2D& operator -=(const Integer2D& v);`	Subtracts the vector `v`.

Nonmember Operations

`bool operator ==(const Integer2D& v1, const Integer2D& v2) const;`	Returns a boolean value indicating whether the two vectors `v1` and `v2` are equal.
`bool operator !=(const Integer2D& v1, const Integer2D& v2) const;`	Returns a boolean value indicating whether the two vectors `v1` and `v2` are not equal.
`Integer2D operator +(const Integer2D& v1, const Integer2D& v2) const;`	Returns the componentwise sum of the vectors `v1` and `v2`.
`Integer2D operator -(const Integer2D& v1, const Integer2D& v2) const;`	Returns the componentwise difference of the vectors `v1` and `v2`.
`Integer2D operator *(const Integer2D& v, int32 t) const;`	Returns a vector for which each component of the vector `v` has been multiplied by `t`.
`Integer2D operator /(const Integer2D& v, int32 t) const;`	Returns a vector for which each component of the vector `v` has been divided by `t`.

Base Classes

Vec2D Vectors use a generic base class to store their components.
