Field Summary

static AccessRule	ALWAYS_HIDDEN This rule always returns hidden access permission.
static AccessRule	ALWAYS_READ_ONLY This rule always returns read-only access permission.
static AccessRule	ALWAYS_READ_WRITE This rule always returns read-write access permission.

Method Summary

AccessPermission

getPermission(Adaptation anAdaptation, Session aSession, SchemaNode aNode) Returns a permission for the arguments specified.

Field Detail

ALWAYS_READ_WRITE

public static final AccessRule ALWAYS_READ_WRITE

This rule always returns read-write access permission.

Method Detail

getPermission

public AccessPermission getPermission(Adaptation anAdaptation,
                                      Session aSession,
                                      SchemaNode aNode)

Returns a permission for the arguments specified.

Warning: if this AccessRule is assigned to a table occurrence node, permission is evaluated with:

• anAdaptation is the current instance, when evaluating table column permission.
• anAdaptation is the current occurrence, when evaluating node permission for a specific table record.

Parameters:

anAdaptation - current adaptation (either an instance or an occurrence)

aSession - current user session

aNode - usually ignored by the implementation - only needed if some introspection is needed: current schema node (when the permission is about the global adaptation, this is the root node)

Returns:

a permission, never null.
