#include "IMP/Model.h"
Inheritance diagram for IMP::Model:Class for storing model, its restraints, constraints, and particles.
The Model maintains a standard IMP container for each of Particle, ScoreState and Restraint object types.
Each Float attribute has an associated range which reflects the range of values that it is expected to take on during optimization. The optimizer can use these ranges to make the optimization process more efficient. By default, the range estimates are simply the range of values for that attribute in the various particles, but it can be set to another value. For example, an attribute storing an angle could have the range set to (0,PI).
The ranges are not enforced; they are just guidelines. In order to enforce ranges, see, for example, IMP::example::ExampleSingletonModifier.

States | |
ScoreStates can be added to the Model in order to keep them alive as long as the model is alive. Being added does affect their ability to perform their required action. See ScoreState for more information.

Accessing attributes | |
All the attribute data associated with each Particle are stored in the Model. For each type of attribute, there are the methods detailed below (where, eg, TypeKey is FloatKey or StringKey) | |

Storing data in the model | |
One can store data associated with the model. This is used, for example, to keep a central ScoreState to normalize rigid body rotational variables. | |
| void | add_data (ModelKey mk, Object *o) |
| Store a piece of data in the model referenced by the key. More... | |
| Object * | get_data (ModelKey mk) const |

| Remove data stored in the model. More... | |
| bool | get_has_data (ModelKey mk) const |

Additional Inherited Members | |

| Construct an object with the given name. More... | |
| virtual void | do_destroy () |
| IMP::Model::Model | ( | std::string | name = "Model %1%" | ) |

| void IMP::Model::add_attribute | ( | TypeKey | attribute_key, |

| void IMP::Model::add_cache_attribute | ( | TypeKey | attribute_key, |
| ParticleIndex | particle, | ||
| Type | value | ||
| ) |
Cache attributes, unlike normal attributes, can be added during evaluation. They are also cleared by the clear_cache_attributes() method. Cache attributes should be used when one is adding data to a particle to aid scoring (eg cache the rigid body collision acceleration structure).
When some pertinent aspect of the particle changes, the clear method should be called (yes, this is a bit vague). Examples where it should be cleared include changing the set of members of a core::RigidBody or their coordinates, changing the members of an atom::Hierarchy.
Store a piece of data in the model referenced by the key.

Sometimes it is useful to be able to make sure the model is up to date.
This method updates all the state but does not necessarily compute the score. Use this to make sure that your containers and rigid bodies are up to date.
