public abstract class LookupTable
extends AbstractObject

An abstract class associated with an outcomeDeclaration used to create A lookup table from A numeric source value to A single outcome value in the declared value set. A lookup table works in the reverse sense to the similar mapping as it defines how A source numeric value is transformed into the outcome value, whereas A (response) mapping defines how the response value is mapped onto A target numeric value.

The transformation takes place using the lookupOutcomeValue rule within responseProcessing or outcomeProcessing.

Constructor Detail

LookupTable

public LookupTable(OutcomeDeclaration parent)

Creates object.

Parameters:

parent - parent of this object

Method Detail

getParent

public OutcomeDeclaration getParent()

Description copied from interface: XmlNode

Gets parent of this node or null (if node is root; for example AssessmentTest).

While testing some nodes (for example expressions) don't have properly set parent, but it is usable only for testing. (Some nodes cannot exists without parent even for testing).

Specified by:

getParent in interface XmlNode

Specified by:

getParent in interface XmlObject

Overrides:

getParent in class AbstractObject

Returns:

parent of this node or null (if node is root; for example AssessmentTest)

getTargetValueBaseType

public BaseType getTargetValueBaseType()

Gets required baseType of target value.

Returns:

required baseType of target value

getDefaultValue

public SingleValue getDefaultValue()

Gets value of defaultValue attribute.

Returns:

value of defaultValue attribute

See Also:

setDefaultValue(org.qtitools.qti.value.SingleValue)

setDefaultValue

public void setDefaultValue(SingleValue defaultValue)

Sets new value of defaultValue attribute.

Parameters:

defaultValue - new value of defaultValue attribute

See Also:

getDefaultValue()

getLookupEntries

public abstract java.util.List<? extends LookupTableEntry> getLookupEntries()

Gets lookupTableEntry children.

Returns:

lookupTableEntry children

getTargetValue

public SingleValue getTargetValue(NumberValue sourceValue)

Gets target value for given source value.

Parameters:

sourceValue - given source value

Returns:

target value for given source value

validateAttributes
