Member Function Documentation

initialize()

template<int dim, typename Number >

void internal::FunctionParser::ParserImplementation< dim, Number >::initialize ( const std::string &  vars, const std::vector< std::string > &  expressions, const std::map< std::string, double > &  constants, const bool  time_dependent = false  )

virtual

Initialize the internal state of the object. This is the same as the inheriting class method - see FunctionParser::initialize() for more information.

Reimplemented in FunctionParser< dim >, and TensorFunctionParser< rank, dim, Number >.

Definition at line 236 of file mu_parser_internal.cc.

init_muparser()

template<int dim, typename Number >

void internal::FunctionParser::ParserImplementation< dim, Number >::init_muparser

Set up the internal muParser objects to parse and evaluate mathematical expressions.

Definition at line 273 of file mu_parser_internal.cc.

do_value()

template<int dim, typename Number >

Number internal::FunctionParser::ParserImplementation< dim, Number >::do_value	(	const Point< dim > &	p,
		const double	time,
		unsigned int	component
	)		const

Compute the value of a single component.

Definition at line 379 of file mu_parser_internal.cc.

do_all_values()

template<int dim, typename Number >

void internal::FunctionParser::ParserImplementation< dim, Number >::do_all_values	(	const Point< dim > &	p,
		const double	time,
		ArrayView< Number > &	values
	)		const

Compute the values of all components.

Member Data Documentation

expressions

template<int dim, typename Number >

std::vector<std::string> internal::FunctionParser::ParserImplementation< dim, Number >::expressions

An array of function expressions (one per component), required to initialize tfp in each thread.

Definition at line 203 of file mu_parser_internal.h.

parser_data

template<int dim, typename Number >

Threads::ThreadLocalStorage<internal::FunctionParser::ParserData> internal::FunctionParser::ParserImplementation< dim, Number >::parser_data

mutableprivate

The muParser objects (hidden with the PIMPL idiom) for each thread (and one for each component).

Definition at line 211 of file mu_parser_internal.h.

constants

template<int dim, typename Number >

std::map<std::string, double> internal::FunctionParser::ParserImplementation< dim, Number >::constants

private

An array to keep track of all the constants, required to initialize fp in each thread.

Definition at line 217 of file mu_parser_internal.h.

var_names

template<int dim, typename Number >

std::vector<std::string> internal::FunctionParser::ParserImplementation< dim, Number >::var_names

private

An array for the variable names, required to initialize fp in each thread.

Definition at line 223 of file mu_parser_internal.h.

initialized

template<int dim, typename Number >

bool internal::FunctionParser::ParserImplementation< dim, Number >::initialized

private

State of usability. This variable is checked every time the function is called for evaluation. It's set to true in the initialize() methods.

Definition at line 229 of file mu_parser_internal.h.

n_vars

template<int dim, typename Number >

unsigned int internal::FunctionParser::ParserImplementation< dim, Number >::n_vars

private

Number of variables. If this is also a function of time, then the number of variables is dim+1, otherwise it is dim. In the case that this is a time dependent function, the time is supposed to be the last variable. If n_vars is not identical to the number of the variables parsed by the initialize() method, then an exception is thrown.
