DataType node. | | public static Object | extractValue(Element typeElem, Element valueElem)
Extract the value from a <DataType> and
a value representing node.
Parameters:
typeElem - the <DataType> element.
Parameters:
valueElem - the value element. | | public static Class | getJavaType(ExternalReference extRef)
Retrieves the Java type from the external reference.
Parameters:
extRef - the external reference. | | public static boolean | isJavaType(ExternalReference extRef)
Checks if the external reference is a Java type.
Parameters:
extRef - the external reference. | | public static boolean | isXMLType(Object type)

| extractDataType | | public static Object extractDataType(Element typeElem) throws IllegalArgumentException(Code) | | Extract the Java data type information from a
DataType node. The type information is coded as follows:
-
if the type is a
<BasicType>, the corresponding
Java class is returned, with
de.danet.an.workflow.api.Participant Participant used to denote "PERFORMER".
-
if the type is
<SchemaType>, but no schema is
specified, org.w3c.dom.Element.class is returned.
-
if the type is
<SchemaType>, and the schema is
specified, the schema is returned is returned
(as SAXEventBuffer).
-
if the type is
<ExternalReference>,
an ExternalReference is returned.
Parameters:
typeElem - a <DataType> element. the type information as specified above.
throws:
IllegalArgumentException - if the type is not recognized. |
| extractValue | | public static Object extractValue(Element typeElem, Element valueElem) throws IllegalArgumentException(Code) | | Extract the value from a <DataType> and
a value representing node.
Parameters:
typeElem - the <DataType> element.
Parameters:
valueElem - the value element. the extracted value which may be null.
throws:
IllegalArgumentException - if the value cannot be extracted. |
| isJavaType | | public static boolean isJavaType(ExternalReference extRef)(Code) | | Checks if the external reference is a Java type.
Parameters:
extRef - the external reference. true if the extzernal referencedescribes a Java type. |
| isXMLType | | public static boolean isXMLType(Object type)(Code) | | Check if the given object is one of the possible
representations of XML types used in WfMOpen.
Parameters:
type - the object representing the type true if the argument represents an XML type |
