Detailed Description

Memory class.

Memory class is used to store variables and functions. It is used by the interpreter to store the variables and functions that are created during the execution of the program

Member Function Documentation

add_function()

void Memory::add_function	(	const string &	name,
		const function_t &	func )

Add a function to the memory.

Add a function to the memory. If the function already exists, the function throws an exception

Parameters

name	Function name
func	Function definition (arguments and body)

Exceptions

runtime_error

If the function already exists

cast_boolean()

bool Memory::cast_boolean ( const unique_ptr< variable_t > & var )

static

Cast a variable to boolean.

Cast a variable to boolean. If the variable type does not match the type to cast, the function throws an exception

Parameters

var	Variable to cast

Returns

bool The casted variable

Exceptions

runtime_error

If the variable type does not match the type to cast

cast_float()

float Memory::cast_float ( const unique_ptr< variable_t > & var )

static

Cast a variable to float.

Cast a variable to float. If the variable type does not match the type to cast, the function throws an exception

Parameters

var	Variable to cast

Returns

double The casted variable

Exceptions

runtime_error

If the variable type does not match the type to cast

cast_int()

int Memory::cast_int ( const unique_ptr< variable_t > & var )

static

Cast a variable to integer.

Cast a variable to integer. If the variable type does not match the type to cast, the function throws an exception

Parameters

var	Variable to cast

Returns

int The casted variable

Exceptions

runtime_error

If the variable type does not match the type to cast

cast_string()

string Memory::cast_string ( const unique_ptr< variable_t > & var )

static

Cast a variable to string.

Cast a variable to string. If the variable type does not match the type to cast, the function throws an exception

Parameters

var	Variable to cast

Returns

string The casted variable

Exceptions

runtime_error

If the variable type does not match the type to cast

get_variable()

unique_ptr< variable_t > Memory::get_variable

(

const string &

name

)

Get the variable value.

Get the value of a variable. If the variable does not exist, return nullptr, otherwise return the variable value

Parameters

name	Variable name

Returns

unique_ptr<variable_t> Variable value

set_variable()

void Memory::set_variable	(	const string &	name,
		const variable_t &	value )

Set the variable value.

Change the value of a variable or create a new one

Parameters

name	Variable name
value	variable value
