parse() [1/2]

ParsedExpression PLMD::Parser::parse ( const std::string &  expression )

static

Parse a mathematical expression and return a representation of it as an abstract syntax tree.

parse() [2/2]

ParsedExpression PLMD::Parser::parse ( const std::string &  expression, const std::map< std::string, CustomFunction *> &  customFunctions  )

static

Parse a mathematical expression and return a representation of it as an abstract syntax tree.

Parameters

customFunctions

a map specifying user defined functions that may appear in the expression. The key are function names, and the values are corresponding CustomFunction objects.

parsePrecedence()

tokenize()

vector< ParseToken > PLMD::Parser::tokenize ( const std::string &  expression )

staticprivate

trim()

string PLMD::Parser::trim ( const std::string &  expression )
