Constructor Detail

ParseTypeAction

public ParseTypeAction(Expression value,
                       QName typeName,
                       Element element,
                       AbstractAction parent)
                throws XMLException
Create a new instance of ParseTypeAction.

Parameters:
value - The value to parse, as an Expression.
typeName - The name of the type.
element - The element from which the action has been unmarshalled. Used for namespace prefix resolution when performing XPath expressions.
parent - The action depending from.
Throws:
XMLException
Method Detail

unmarshal

public static AbstractAction unmarshal(AbstractAction parent,
                                       Element element)
                                throws XMLException
XML unmarshaller for ParseTypeAction.

Parameters:
parent - The action depending from
element - The XML element to unmarshall.
Returns:
The ParseTypeAction created.
Throws:
XMLException - When the element and its content is not those expected.

getComputedValue

public Object getComputedValue(DataSet dataSet)
                        throws ExecutionException,
                               XPathException
Return the computed value of the property, by parsing a data type.

Specified by:
getComputedValue in interface Computable
Specified by:
getComputedValue in class AbstractSetAction
Parameters:
dataSet - The set of datas used when the name is computed.
Returns:
The data typed.
Throws:
ExecutionException - If the computation can't be performed.
XPathException
