Constructor Detail

OutcomeConditionExpressionChild

public OutcomeConditionExpressionChild(OutcomeCondition parent)

Construct condition rule child.

Parameters:

parent - parent of this condition rule child

Method Detail

getExpression

public Expression getExpression()

Gets expression child (condition).

Returns:

expression child (condition)

See Also:

setExpression(org.qtitools.qti.node.expression.Expression)

setExpression

public void setExpression(Expression expression)

Sets new expression child (condition).

Parameters:

expression - new expression child (condition)

getExpression()

getRequiredCardinalities

public Cardinality[] getRequiredCardinalities(int index)

Description copied from interface: ExpressionParent

Gets list of all acceptable cardinalities which can child expression at given position produce.

For example delete expression returns single cardinality for index 0 and list of multiple and ordered cardinality for index 1.

Result of this method can change in time.

Static example is expression or. Expression or accepts only single cardinality for any index.

Dynamic example is expression match. Expression match accepts any cardinality of its children, but this cardinality must be same for all its children.

Specified by:

getRequiredCardinalities in interface ExpressionParent

Parameters:

index - position of child expression in this parent

Returns:

list of all possible cardinalities which can child expression at given position produce

getRequiredBaseTypes

public BaseType[] getRequiredBaseTypes(int index)

Description copied from interface: ExpressionParent

Gets list of all acceptable baseTypes which can child expression at given position produce.

Result of this method can change in time.

Static example is expression or. Expression or accepts only boolean baseType for any index.

Dynamic example is expression match. Expression match accepts any baseType of its children. but this baseType must be same for all its children.

Specified by:

getRequiredBaseTypes in interface ExpressionParent

Parameters:

index - position of child expression in this parent

Returns:

list of all acceptable baseTypes which can child expression at given position produce

evaluate

public boolean evaluate()
                 throws QTIProcessingInterrupt

Description copied from class: OutcomeConditionChild

Evaluates all child outcomeRules and returns true.

Overrides:

evaluate in class OutcomeConditionChild

Returns:

true

Throws:

QTIProcessingInterrupt
