Detailed Description

Mathematical expressions parser (base parser engine).

Version 1.30 (20080413)

This is the implementation of a bytecode based mathematical expressions parser. The formula will be parsed from string and converted into a bytecode. Future calculations will be done with the bytecode instead the formula string resulting in a significant performance increase. Complementary to a set of internally implemented functions the parser is able to handle user defined functions and variables.

Member Typedef Documentation

◆ exception_type

typedef ParserError mu::ParserBase::exception_type

Type of the error class.

Included for backwards compatibility.

Definition at line 92 of file muParserBase.h.

◆ ParseFunction

typedef value_type(ParserBase::* mu::ParserBase::ParseFunction) () const

private

Typedef for the parse functions.

The parse function do the actual work. The parser exchanges the function pointer to the parser function depending on which state it is in. (i.e. bytecode parser vs. string parser)

◆ stringbuf_type

typedef std::vector<string_type> mu::ParserBase::stringbuf_type

◆ EnableBuiltInOprt()

void mu::ParserBase::EnableBuiltInOprt ( bool a_bIsOn = true )

Enable or disable the built in binary operators.

Exceptions

nothrow

See also: m_bBuiltInOp, ReInit()

If you disable the built in binary operators there will be no binary operators defined. Thus you must add them manually one by one. It is not possible to disable built in operators selectively. This function will Reinitialize the parser by calling ReInit().

◆ EnableByteCode()

void mu::ParserBase::EnableByteCode ( bool a_bIsOn = true )

Enable or disable parsing from Bytecode.

Attention: There is no reason to disable bytecode. It will drastically decrease parsing speed.

◆ EnableOptimizer()

void mu::ParserBase::EnableOptimizer ( bool a_bIsOn = true )

	)		const

Create an error containing the parse error position.

This function will create an Parser Exception object containing the error text and its position.

Parameters

a_iErrc	[in] The error code of type EErrorCodes.
a_iPos	[in] The position where the error was detected.
a_strTok	[in] The token string representation associated with the error.

Exceptions

ParserException always throws thats the only purpose of this function.

◆ Eval()

value_type mu::ParserBase::Eval ( ) const

inline

Calculate the result.

A note on const correctness: I consider it important that Calc is a const function. Due to caching operations Calc changes only the state of internal variables with one exception m_UsedVar this is reset during string parsing and accessible from the outside. Instead of making Calc non const GetUsedVar is non const because it explicitely calls Eval() forcing this update.

Precondition: A formula must be set.; Variables must have been set (if needed)

See also: m_pParseFormula

Returns: The evaluation result

Exceptions

ParseException if no Formula is set or in case of any other error related to the formula.
