public class OutcomeMaximum
extends OutcomeMinMax

This expression, which can only be used in outcomes processing, simultaneously looks up the normalMaximum value of an outcome variable in A sub-set of the items referred to in A test. Only variables with single cardinality are considered. If any of the items within the given subset have no declared maximum the result is NULL, otherwise the result has cardinality multiple and base-type float.

Constructor Detail

OutcomeMaximum

public OutcomeMaximum(ExpressionParent parent)

Constructs expression.

Parameters:

parent - parent of this expression

Method Detail

getClassTag

public java.lang.String getClassTag()

Description copied from interface: XmlNode

Gets QTI class name of this node.

QTI class name has very important role during loading/saving nodes.

For example: Java class name is AssessmentTest; QTI class name is assessmentTest.

Specified by:

getClassTag in interface XmlNode

Specified by:

getClassTag in class AbstractNode

Returns:

QTI class name of this node

evaluateSelf

protected Value evaluateSelf(int depth)

Description copied from class: AbstractExpression

Evaluates this expression. All children must be already evaluated. Contains no checks.

Specified by:

evaluateSelf in class AbstractExpression

Parameters:

depth - depth of this expression in expression tree (root's depth = 0)

Returns:

result of evaluation
