Description copied from interface: DataSecurityProvider

Checks row instance privilege. This method is called when evaluating the allows.priv EL. Privilege check for XDB is a DataPermission check of the privilege with the aclids on the row instance. Privilege check for native JAAS case would be AccessConntroller.checkPermission of java permission.

Specified by:

checkPrivilege in interface DataSecurityProvider

Parameters:

row - The row instance to be checked for privilege.

privToCheck - The privilege to be checked.

attrDef - The attribute definition.

defObject - The entity or view def.

Returns:

A PrivilegeHoder for the privilege checked.

public java.lang.String getPrivilegeFilterWhereClause(java.lang.String privsRequiredToView,
                                                      StructureDef defObject,
                                                      java.lang.String entityRefName)

Description copied from interface: DataSecurityProvider

Gets the where clause for read restriction. XDB security with read enabled in the database should return null.

Specified by:

getPrivilegeFilterWhereClause in interface DataSecurityProvider

Parameters:

privsRequiredToView - The row filter privileges for read.

defObject - The definition object in which the filter apply.

entityRefName - The name of the entiry reference in which the filter apply.

Returns:

A string containing the sql expression for read restriction where clause fragment.

Description copied from interface: DataSecurityProvider

Optional: XDB data security requires additional sql attribute sys_get_aclids(table_alias, privsToCheck) for getting aclids of row instances in the query. The return type of this is XMLType and require a special java type to retrieve data from query result. This method is not call unless getImplicitSecurityAttrSQLExpression return an expression.

Specified by:

getImplicitSecurityAttrSQLExpressionAndDomain in interface DataSecurityProvider

Parameters:

privsToCheck - The privileges for the SQL expression.

defObject - The entity or view definition.

Returns:

The a Map of SQL expression and domain class of security attributes.
