buildLinkMap

protected Hashtable buildLinkMap(Vector a_classes,
                                 String a_classA,
                                 String a_classB,
                                 Locale a_locale)
                          throws WTException

Specified by:

buildLinkMap in class JoinInfo

Throws:

WTException

buildLinkMap

protected Hashtable buildLinkMap(Vector classesA,
                                 String classB,
                                 Hashtable a_linkMap,
                                 Locale a_locale)
                          throws WTException

Builds a Hashtable of valid join information using introspection. A join is specified via a classB property which has a type that is a valid reference sub-class. If the property is constrained to reference a specific type, then the classesA vector is checked to ensure that a type compatible class exists.

Specified by:

buildLinkMap in class JoinInfo

Parameters:

classesA - classes to check

classB - class to check

a_linkMap - existing map to add join properties to

a_locale - Locale for display names

Returns:

Hashtable where keys are the join property name and the elements are the ClassInfo of the property type

Throws:

WTException
