Examples of de.danet.an.workflow.api.ProcessMgr

de.danet.an.workflow.api.ProcessMgr
Interface ProcessMgr adds some functions to the {@link WfProcessMgr OMG process manager}.
The meta information returned by contextSignature and resultSignature defined in WfProcessMgr uses Java classes to represents primitive types, as specified for {@link de.danet.an.workflow.omgcore.ProcessDataInfo ProcessDataInfo}. In addition the type of a data item can be indicated as

org.w3c.dom.Element.class

denotes XML with unknown structure. Values of this type are represented as instances of SAXEventBuffer.

an instance of SAXEventBuffer

denotes XML with the known structure represented by the XML in the event buffer. Values of this type are represented as instances of SAXEventBuffer.

an instance of ExternalReference

denotes the type as specified in the process definition. If a Java type is specified as fully qualified Java class name in the localtion attribute, "java:" is prepended as protocol and values are of the specified type. Else values of this type are represented as instances of SAXEventBuffer.
