Detailed Description

template<typename real_t>
class matheval::Parser< real_t >

Class interface.

This class hides the grammar, AST, and AST traversal behind some member functions.

Template Parameters

evaluate()

template<typename real_t >

real_t matheval::Parser< real_t >::evaluate ( typename detail::eval_ast< real_t >::symbol_table_t const &  st )

inline

Evaluate the AST with a given symbol table.

Parameters

[in]

st

the symbol table for variables

parse() [1/2]

template<typename real_t >

template<typename Iterator >

Parser::parse ( Iterator  first, Iterator  last  )

inline

Parse an expression.

This function builds the grammar and parses the iterator into an AST.

Parameters

[in]	first	iterator to the start of the input sequence
[in]	last	iterator to the end of the input sequence

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
