public class OutcomeMinimum
extends OutcomeMinMax

This expression, which can only be used in outcomes processing, simultaneously looks up the normalMinimum value of an outcome variable in A sub-set of the items referred to in A test. Only variables with single cardinality are considered. Items with no declared minimum are ignored. The result has cardinality multiple and base-type float.

Constructor Detail

OutcomeMinimum

public OutcomeMinimum(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
