Member Function Documentation

addOperations()

void QtxEvalSetBase::addOperations ( const QStringList &  list )

protected

Add operation names to the internal list of operations.

Parameters

list	operations to be added

References myOpers.

addTypes()

void QtxEvalSetBase::addTypes ( const ListOfTypes &  list )

protected

Add operand types.

Parameters

list	operand types to be added

References myTypes.

bracketsList()

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

virtual

Get list of brackets.

Parameters

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

Implements QtxEvalSet.

Reimplemented in QtxEvalSetSets.

isValid()

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

virtual

Check operation validity.

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.

References QtxEvalExpr::InvalidOperation, myTypes, QtxEvalExpr::OK, QtxEvalExpr::OperandsNotMatch, and QtxEvalSet::priority().

operationList()

void QtxEvalSetBase::operationList ( QStringList &  list ) const

virtual

Get the list of possible operations.

Parameters

list	returning list of operations supported by the class

Implements QtxEvalSet.
