Interface AccessController

All Known Implementing Classes:

AccessControllerAdapter

public interface AccessController

This class encapsulates the access control decision for an object array. This is used to provide access control at various levels as result objects are built.

Supported API: false

Extendable: false

Field Summary

static String

FILTER Label for the attribute; Filter for processing multiple rows.

Method Summary

WhereExpression	buildAccessCondition(Vector a_tableInfos, boolean a_useOuterJoin) Build WHERE condtions for the specified class and the current principal.
boolean	checkAccess(Object a_object) Check access of the object.
boolean	checkAccess(Object[] a_objects) Check access of all objects in the array.
void	checkQuery(StatementSpec a_statementSpec) Supported API: false
FilterResultProcessor	getFilter() Gets the value of the attribute: FILTER.
Vector	getItemBuilders(Vector a_tableInfos, ResultBuilder a_resultBuilder, int a_itemOffset) Retrun a Vector of ItemBuilders that will be used to retrieve Access Control related objects.
ItemBuilder	getViewItemBuilder(ClassInfo a_classInfo, String a_alias) Retrun a ItemBuilders that will be used to retrieve Access Control related objects.
boolean	isItemBuilderProvided() Supported API: false
