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, Map cache, 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 | loadProperties(Element e, ClauseSet cs)
Load the properties into the clause set. | | protected void | loadProperties(Element e, Query q)
Load the properties into the query. |

| getFunctionType | | protected String getFunctionType(Function f)(Code) | | Get the type of the function, e.g. GenericDriver.JFunction or GenericDriver.SQL_FUNCTION.
Parameters:
f - a function a string |

| importChild | | protected Object importChild(Element parent, String name, GenericDriver driver, Map cache, LogicFactory lfactory) throws XKBException(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:
e - the parent element
Parameters:
name - the name of the child tag
Parameters:
driver - the generic driver
Parameters:
cache - a cache used to identify objects that have an id
Parameters:
lfactory - the logic factory used to create objects an object
exception:
an - XKBException is thrown if import fails |
| importChildren | | protected Object importChildren(Element parent, String name, GenericDriver driver, Map cache, LogicFactory lfactory, Class targetType) throws XKBException(Code) | | 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. The name can be null, in this case all
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:
e - the parent element
Parameters:
name - the name of the child tag
Parameters:
driver - the generic driver
Parameters:
cache - a cache used to identify objects that have an id
Parameters:
lfactory - the logic factory used to create objects
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 - XKBException is thrown if import fails |
