public class NewInstanceModel
A rule clause representing the creation of an object via a java type's constructor. This can only be used as a rule action, in which the resulting object will be added to the rule's context's working memory. A new-instance requires a type-alias, which is the java class which contains the constructor which will be executed. The arguments of a new-instance can be:

public org.apache.xmlbeans.XmlObject createNewXmlObject(String clauseType) throws IllegalArgumentException
ClauseModel
Subclasses need to implement this to create an appropriately typed and filled root XmlObject which represents the ClauseModel. The return value from this needs to be accepted from ClauseModel.setXmlObject(java.lang.String, org.apache.xmlbeans.XmlObject)
for the specified clauseType.
createNewXmlObject
in class ClauseModel
clauseType
- the clause type of the clause.IllegalArgumentException
- thrown on an unsupproted clauseType.public void setXmlObject(String clauseType, org.apache.xmlbeans.XmlObject clause) throws IllegalArgumentException
ClauseModel
This will fire ChangeEvents
for clauseType and rootXmlObject.
Subclasses should override to call super.setXmlObject() and do any type checking and verification.
It is not expected that ClauseModels are valid after a call to this method which throws an exception, although the caller could recall this method with valid data.
setXmlObject
in class ClauseModel
clauseType
- the clause type of the clause.clause
- the root xml object of the clause.IllegalArgumentException
- thrown if the clause is not valid for the ClauseModel or clauseType.protected boolean determineIsComplete()
