Detailed Description

Stores interdependent getfem objects.

Yves Renard
February 19, 2005 Stored object :

A type of object to be stored should derive from dal::static_stored_object and a key should inherit from static_stored_object_key with an overloaded "compare" method.

To store a new object, you have to test if the object is not already stored and then call dal::add_stored_object:

pstatic_stored_object_key p = make_shared<your_object_key>(parameters);
add_stored_object(p, make_shared<your_object>(parameters));

You can add a dependency of your new object with


and then your object will be automatically deleted if the second object is deleted. The dependency can be added within the add_stored_object call:

add_stored_object(new your_object_key(parameters),
new your_object(parameters),

std::shared_ptr are used.

pstatic_stored_object search_stored_object(pstatic_stored_object_key k)
Gives a pointer to an object from a key pointer.
void add_stored_object(pstatic_stored_object_key k, pstatic_stored_object o, permanence perm)
Add an object with two optional dependencies.
void add_dependency(pstatic_stored_object o1, pstatic_stored_object o2)
Add a dependency, object o1 will depend on object o2.
