grant

public void grant(Schema schema,
 Access access)

Defines access to all cubes and dimensions in a schema.

Parameters:

schema - Schema whose access to grant/deny.

access - An access code

getAccess

public Access getAccess(Schema schema)

Description copied from interface: Role

Returns the access this role has to a given schema.

Specified by:

getAccess in interface Role

public void grant(Cube cube,
 Access access)

Defines access to a cube.

Parameters:

cube - Cube whose access to grant/deny.

access - An access code

getAccess

public Access getAccess(Cube cube)

Description copied from interface: Role

Returns the access this role has to a given cube.

Specified by:

getAccess in interface Role

grant

public void grant(Dimension dimension,
 Access access)

Defines access to a dimension.

Parameters:

dimension - Dimension whose access to grant/deny.

access - An Access instance

getAccess

public Access getAccess(Dimension dimension)

Description copied from interface: Role

Returns the access this role has to a given dimension.

Specified by:

getAccess in interface Role

grant

public void grant(Hierarchy hierarchy,
 Access access,
 Level topLevel,
 Level bottomLevel,
 Role.RollupPolicy rollupPolicy)

Defines access to a hierarchy.

Parameters:

hierarchy - Hierarchy whose access to grant/deny.

access - An access code

topLevel - Top-most level which can be accessed, or null if the highest level. May only be specified if access is Access.CUSTOM.

bottomLevel - Bottom-most level which can be accessed, or null if the lowest level. May only be specified if access is Access.CUSTOM.

rollupPolicy - Rollup policy

getAccess

public Access getAccess(Hierarchy hierarchy)

Description copied from interface: Role

Specified by:

getAccess in interface Role

getAccessDetails

public Role.HierarchyAccess getAccessDetails(Hierarchy hierarchy)

grant

public void grant(Member member,
 Access access)

Defines access to a member in a hierarchy.

Notes:

1. The order of grants matters. If you grant/deny access to a member, previous grants/denials to its descendants are ignored.
2. Member grants do not supersde top/bottom levels set using grant(Hierarchy, Access, Level, Level, mondrian.olap.Role.RollupPolicy).
3. If you have access to a member, then you can see its ancestors even those explicitly denied, up to the top level.
