Get the object with the uri found in the tag. | | protected Object | importChild(Element parent, String name, GenericDriver driver, ObjectPersistencyService ops, LogicFactory lfactory)
Utility method to import a child (the first child) with a certain name (not the tag name but the symbolic name
as defined in GenericDriver) of the given parent element. | | protected Object | importChildren(Element parent, String name, GenericDriver driver, ObjectPersistencyService ops, LogicFactory lfactory, Class targetType)
Utility method to import the children with a certain name (not the tag name but the symbolic name
as defined in GenericDriver) of the given parent element. | | protected void | importProperties(Element parent, PropertiesSupport ps)
Import the properties of an object implementing PropertiesSupport. | | abstract public void | printDTD(StringBuffer out)

| exportProperties | | protected void exportProperties(Element parent, PropertiesSupport ps)(Code) | | Export the properties of an object implementing PropertiesSupport.
Parameters:
parent - the parent element
Parameters:
ps - the object implementing PropertiesSupport |
| getClauseSetType | | protected String getClauseSetType(ClauseSet cs)(Code) | | Get the type of clause set, e.g. GenericDriver.FACT or GenericDriver.RULE.

| importChild | | protected Object importChild(Element parent, String name, GenericDriver driver, ObjectPersistencyService ops, LogicFactory lfactory) throws ZKBException(Code) | | Utility method to import a child (the first child) with a certain name (not the tag name but the symbolic name
as defined in GenericDriver) of the given parent element.
Parameters:

child elements will be imported. The target type argument specifies the type of the objects
in the array. Note that we return an object , not an array. But this object can be casted to
an array of the target type, e.g. like in
Term[] terms = importChildren(e,null,driver,cache,lfactory,Term.class)

Parameters:
targetType - the expected type of elements in the array an object that can be casted to an array of elements of the target type
exception:
an - ZKBException is thrown if import fails |
