program_card_functor_image_png::~program_card_functor_image_png

(

)

[virtual]

const std::string &

filename

)

[private]

The constructor. It is private on purpose, use the create class method instead.

Parameters:

filename

The name of the file to be written.

program_card_functor_image_png::program_card_functor_image_png

(

)

[private]

Member Function Documentation

program_card_functor_image::pointer program_card_functor_image_png::create

(

const std::string &

filename

)

[static]

The create class method is used to create a new dynamically allocated instance of this class.

Parameters:

filename

The path of the output file to be written.

Returns:

a managed pointer to a new instance of this class.

Definition at line 40 of file png.cc.

void program_card_functor_image_png::operator()	(	unsigned	card_num,
		unsigned	card_count,
		const unsigned char *	data,
		size_t	data_size
	)		[virtual]

The function call operator is overloaded to implement the functionality (that's why it's called a functor).

Parameters:

card_num	The number of the card within the set (1 based).
card_count	The number of cards in the set.
data	The base of the array of bytes containing the program.
data_size	The number of bytes in this card image (> 0, <= 40).

Implements program_card_functor.

Definition at line 47 of file png.cc.

program_card_functor_image_png& program_card_functor_image_png::operator=

(

const program_card_functor_image_png &

rhs

)

[private]

The assignment operator. Do not use.

Parameters:

rhs	The right hand side of the assignment.
