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 >.

void internal::FunctionParser::ParserImplementation< dim, Number >::init_muparser | ( | ) | const |
Set up the internal muParser objects to parse and evaluate mathematical expressions.

const double | time, | ||

Compute the values of all components.

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 202 of file mu_parser_internal.h.

mutableprivate |
The muParser objects (hidden with the PIMPL idiom) for each thread (and one for each component).
Definition at line 210 of file mu_parser_internal.h.
|
private |
An array to keep track of all the constants, required to initialize fp in each thread.
Definition at line 216 of file mu_parser_internal.h.
|
private |
An array for the variable names, required to initialize fp in each thread.
Definition at line 222 of file mu_parser_internal.h.

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

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.
