All Implemented Interfaces:

EventListener, NodeEventListener, RelationEventListener

Direct Known Subclasses:

PeopleContexts

public class Contexts
extends MMObjectBuilder

Representation of a 'context', which can be read as a valid value of the 'owner' field of any object in MMBase. Rights are distributed using this thing. This is part of cloud context security, so the 'context' values need to be present in the cloud.

Method Detail

createProvider

protected ContextProvider createProvider()

init

public boolean init()

Description copied from class: MMObjectBuilder

Initializes this builder The property 'mmb' needs to be set for the builder before this method can be called. The method retrieves data from the TypeDef builder, or adds data to that builder if the current builder is not yet registered.

Overrides:

init in class MMObjectBuilder

Returns:

true if init was completed, false if uncompleted.

See Also:

MMObjectBuilder.create()

Javadoc:

getBuilder

public static Contexts getBuilder()

Staticly receives the MMObjectBuilder instance (cast to Contexts). A utility function.

getProvider

public ContextProvider getProvider()

isOwnNode

protected boolean isOwnNode(User user,
                            MMObjectNode node)

mayDo

protected boolean mayDo(MMObjectNode user,
                        MMObjectNode contextNode,
                        Operation operation,
                        boolean checkOwnRights)

check

public Authorization.QueryCheck check(User userContext,
                                      Query query,
                                      Operation operation)

Implements check function with same arguments of Authorisation security implementation

See Also:

Verify.check(UserContext, Query, Operation)

getDefaultContextNode

public final MMObjectNode getDefaultContextNode()

setDefaults

public void setDefaults(MMObjectNode node)

Makes sure unique values and not-null's are filed

Overrides:

setDefaults in class MMObjectBuilder

Parameters:

node - The node to set the defaults of.

getUserNode

protected MMObjectNode getUserNode(UserContext user)

Javadoc:

getGroupOrUserNode

protected MMObjectNode getGroupOrUserNode(Parameters a)

toString

public String toString(MMObjectNode n)

Description copied from class: MMObjectBuilder

Implements for MMObjectNode

Overrides:

toString in class MMObjectBuilder
