Method Detail

checkPermission

Access checkPermission(Document doc,
                       ACP mergedAcp,
                       NuxeoPrincipal principal,
                       String permission,
                       String[] resolvedPermissions,
                       String[] additionalPrincipals)

Checks given permission for doc and principal.

Note that for the Browse permission, which is also implemented in SQL using getQueryTransformer(java.lang.String), a security policy must never bypass standard ACL access, it must only return DENY or UNKNOWN. Failing to do this would make direct access and queries behave differently.

Parameters:

doc - the document to check

mergedAcp - merged ACP resolved for this document

principal - principal to check

permission - permission to check

resolvedPermissions - permissions or groups of permissions containing permission

Returns:

access: GRANT, DENY, or UNKNOWN. When UNKNOWN is returned, following policies or default core security are applied.

isRestrictingPermission

boolean isRestrictingPermission(String permission)

Checks if this policy is restricting the given permission.

Queries check the BROWSE permission.

Parameters:

permission - the permission to check for

Returns:

true if the policy restricts the permission

isExpressibleInQuery

boolean isExpressibleInQuery(String repositoryName)

Checks if this policy can be expressed in a query for given repository.

If not, then any query made will have to be post-filtered.

Parameters:

repositoryName - the target repository name.

Returns:

true if the policy can be expressed in a query

isExpressibleInQuery

boolean isExpressibleInQuery(String repositoryName,
                             String queryLanguage)

Checks if this policy can be expressed in a string-based query for given repository.

If not, then any query made will have to be post-filtered, if possible, otherwise denied.

Parameters:

repositoryName - the target repository name.

Returns:

true if the policy can be expressed in a string-based query

Since:

5.7.2

getQueryTransformer

SQLQuery.Transformer getQueryTransformer(String repositoryName)

Get the transformer to use to apply this policy to a query.

Called only when isExpressibleInQuery(String) returned true

Parameters:

repositoryName - the target repository name.

Returns:

the transformer

getQueryTransformer

SecurityPolicy.QueryTransformer getQueryTransformer(String repositoryName,
                                                    String queryLanguage)

Get the string-based transformer to use to apply this policy to a query.

Called only when isExpressibleInQuery(String, String) returned true

Parameters:

repositoryName - the target repository name.

Returns:

the transformer

Since:

5.7.2
