◆ InitCharSets()

void qmu::QmuFormulaBase::InitCharSets ( )

virtual

InitCharSets init character set for parser.

QMuParser require setting character set for legal characters. Because we try make our expresion language independent we set all posible unique characters from all alphabets.

Reimplemented from qmu::QmuParser.

◆ RemoveAll()

void qmu::QmuFormulaBase::RemoveAll	(	QMap< int, QString > &	map,
		const QString &	val
	)

static

RemoveAll remove token from token list.

Standard Qt class QMap doesn't have method RemoveAll. Example: remove "-" from tokens list if exist. If don't do that unary minus operation will broken.

Parameters

map	map with tokens
val	token that need delete
