public class Mapping
extends AbstractObject

A special class used to create A mapping from A source set of any baseType (except file and duration) to A single float. Note that mappings from values of base type float should be avoided due to the difficulty of matching floating point values, see the match operator for more details. When mapping containers the result is the sum of the mapped values from the target set.

Constructor Detail

Mapping

public Mapping(ResponseDeclaration parent)

Creates object.

Parameters:

parent - parent of this object

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

getParent

public ResponseDeclaration 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)

getDefaultValue

public java.lang.Double getDefaultValue()

Gets value of defaultValue attribute.

Returns:

value of defaultValue attribute

See Also:

setDefaultValue(java.lang.Double)

setDefaultValue

public void setDefaultValue(java.lang.Double defaultValue)

Sets new value of defaultValue attribute.

Parameters:

defaultValue - new value of defaultValue attribute

See Also:

getDefaultValue()

getLowerBound

public java.lang.Double getLowerBound()

Gets value of lowerBound attribute.

Returns:

value of lowerBound attribute

See Also:

setLowerBound(java.lang.Double)

setLowerBound

public void setLowerBound(java.lang.Double lowerBound)

Sets new value of lowerBound attribute.

Parameters:

lowerBound - new value of lowerBound attribute

See Also:

getLowerBound()

getUpperBound

public java.lang.Double getUpperBound()

Gets value of upperBound attribute.

Returns:

value of upperBound attribute

See Also:

setUpperBound(java.lang.Double)

setUpperBound

public void setUpperBound(java.lang.Double upperBound)

Sets new value of upperBound attribute.

Parameters:

upperBound - new value of upperBound attribute

See Also:

getUpperBound()

getMapEntries

public java.util.List<MapEntry> getMapEntries()

Gets mapEntry children.

Returns:

mapEntry children

validate

public ValidationResult validate()

Description copied from interface: Validatable

Validates this object.

Specified by:

validate in interface Validatable

Overrides:

validate in class AbstractNode

Returns:

validation result

getTargetValue

public FloatValue getTargetValue(Value sourceValue)

Gets target value for given source value.

Parameters:

sourceValue - given source value

Returns:

target value for given source value
