void QtxEvalSetBase::addOperations ( const QStringList &  list )

Parameters

list	operations to be added

void QtxEvalSetBase::addTypes ( const ListOfTypes &  list )

protected

Parameters

list	operand types to be added

References myTypes.

void QtxEvalSetBase::bracketsList ( QStringList &  list, bool  open  ) const

virtual

Parameters

list	returning list of brackets
open	if true, collect opening brackets, or closing brackets otherwise

Implements QtxEvalSet.

Reimplemented in QtxEvalSetSets.

QtxEvalExpr::Error QtxEvalSetBase::isValid ( const QString &  op, const QVariant::Type  t1, const QVariant::Type  t2  ) const

virtual

If the operation is valid, QtxEvalExpr::OK is returned. If types of operands are invalid, the function returns QtxEvalExpr::OperandsNotMatch or QtxEvalExpr::InvalidOperation.

Parameters

op	operation
t1	first operand type
t2	second operand type

Returns

error code (QtxEvalExpr::Error)

Implements QtxEvalSet.

Reimplemented in QtxEvalSetSets.

void QtxEvalSetBase::operationList ( QStringList &  list ) const

Parameters

list	returning list of operations supported by the class

Implements QtxEvalSet.
