Constructor & Destructor Documentation

State() [1/3]

geometrize::State::State

(

)

: m_score{-1.0}, m_alpha{0}, m_shape{nullptr} {}

State() [2/3]

geometrize::State::State	(	const std::shared_ptr< geometrize::Shape > &	shape,
		std::uint8_t	alpha
	)

Creates a new state.

Parameters

shape	The shape.
alpha	The color alpha of the geometric shape.

                                                                                :
    m_score{-1.0}, m_alpha{alpha}, m_shape{shape}
{
    m_shape->setup(*m_shape);

Member Function Documentation

mutate()

geometrize::State geometrize::State::mutate

(

)

mutate Modifies the current state in a random fashion.

Returns

The old state, useful for undoing the mutation or keeping track of previous states.

{
    geometrize::State oldState(*this);
    m_shape->mutate(*m_shape);
    m_score = -1;
    return oldState;
}

operator=()

State & geometrize::State::operator=

(

const State &

other

)

{
    if(this != &other) {
        m_score = other.m_score;
        m_alpha = other.m_alpha;
        m_shape = other.m_shape->clone();
    }
    return *this;
}

Member Data Documentation

m_alpha

std::uint8_t geometrize::State::m_alpha

The alpha of the shape.

m_score

double geometrize::State::m_score

The score of the state, a measure of the improvement applying the state to the current bitmap will have.

m_shape

std::shared_ptr<geometrize::Shape> geometrize::State::m_shape

The geometric primitive owned by the state.
