RelationAttributeAccess
public RelationAttributeAccess(String qualifier, boolean isSource, boolean localized, boolean singleValued) Creates a new attribute access for one end of a relation.- Parameters:
qualifier- the relation qualifier - must be the same at both ends for unidirectional relationsisSource- tells whether this end is the source - only one end can be sourcelocalized- tells whether the relation value is localized or notsingleValued- for the special case when the 1-end of an unidirectional 1:n relation is described - use with care, mostly using a simple typed property should be preferred

setValue
public final void setValue(SessionContext ctx, Item item, Object value) throws JaloTypeException, JaloInvalidParameterException, JaloSecurityException Description copied from interface:AttributeAccessStores the attribute data for a given item.- Specified by:
setValuein interfaceAttributeAccess- Parameters:
ctx- the current session context - e.g. specifies the session languageitem- the item to store data forvalue- the value to store- Throws:
JaloTypeException- in case the attribute type does not allow storing this valueJaloInvalidParameterException- in case the value is not compatible with this attributeJaloSecurityException- in case there are security constraints which do not allow this value to be written
-
getValue
public final Object getValue(SessionContext ctx, Item item) throws JaloTypeException, JaloInvalidParameterException, JaloSecurityException Description copied from interface:AttributeAccessRetrieves the attribute data from a given item. Primitive data types likeintare wrapped into their object instances.- Specified by:
getValuein interfaceAttributeAccess- Parameters:
ctx- the current session context - e.g. specifies the session languageitem- the item to get data from- Returns:
- the data value
- Throws:
JaloTypeException- in case the attribute type does not allow reading this valueJaloInvalidParameterException- in some data required for reading the value is missing or not as expected ( like missing session language )JaloSecurityException- in case there are security constraints which do not allow reding this value
