All Implemented Interfaces:

IdcComparator

public class UserDocumentAccessFilter

extends java.lang.Object

implements IdcComparator

This class is used to optimize the testing of access of a user against an application entity that has document style security credentials. In order to get good performance, this class is hardwired in its understanding of groups and accounts. This class reduces flexibility when changing the implementation of security but improves the speed of execution. This class makes two assumptions: 1. The level of desired access has already been chosen (Read, Write, Deleted, or Admin). 2. All checks made with security group and account have all already been lower cased.

Field Summary

boolean	m_accessAllAccounts Set to true if user has access to "#all" account.
boolean	m_accessNoneAccount Set to true user has access to "#none" account.
java.lang.String[]	m_accounts Accounts (not including "#none" or "#all")
int	m_appRights Sub admin flags.
java.lang.String[]	m_groups Groups accessible (all in lower case).
boolean	m_isAdmin Set to true if being accessed by user with admin role.

Constructor Summary

UserDocumentAccessFilter(java.util.Vector groups, java.util.Vector accounts, boolean isAdmin, int appRights)
Constructs filter with specified list of groups and accounts.

Method Summary

boolean	checkAccess(java.lang.String group, java.lang.String account) Checks to see if filter allows access to a security group and account.
boolean	checkStringListEqual(java.lang.String[] list1, java.lang.String[] list2) Checks to see if two string arrays are identical.
int	compare(java.lang.Object o1, java.lang.Object o2) Compares to strings, used as callback interface for sorting.
boolean	isEqualSecurity(UserDocumentAccessFilter filter) Checks to see if this filter will filter the same documents as another.

Constructs filter with specified list of groups and accounts.

Method Detail

isEqualSecurity

public boolean isEqualSecurity(UserDocumentAccessFilter filter)

Checks to see if this filter will filter the same documents as another.

checkStringListEqual

public boolean checkStringListEqual(java.lang.String[] list1,
                                    java.lang.String[] list2)

Checks to see if two string arrays are identical.

checkAccess

public boolean checkAccess(java.lang.String group,
                           java.lang.String account)
