Detailed Description
template<typename PolicyT, typename FeaturesT>
class ignition::physics::Entity< PolicyT, FeaturesT >
This is the base class of all "proxy objects". The "proxy objects" are essentially interfaces into the actual objects which exist inside of the various physics engine implementations. The proxy objects contain the minimal amount of data (e.g. a unique identifier, a reference-counter for the implementation object, and a reference to the implementation interface that it needs) necessary to interface with the object inside of the implementation that it refers to.
Examples of entities are the Link class, Joint class, and Model class.
Member Typedef Documentation
◆ Features
| using Features = FeaturesT |
◆ Pimpl
◆ Policy
| using Policy = PolicyT |
Constructor & Destructor Documentation
◆ Entity() [1/2]
|
protected |
Constructor for the Entity.
- Parameters
-
[in] _pimpl Pointer to the implementation plugin for this entity [in] _identity The identity of this entity
◆ Entity() [2/2]
|
protected |
Constructor that allows the pimpl to be moved instead of copied.
- Parameters
-
[in] _pimpl Pointer to the implementation plugin for this entity [in] _identity The identity of this entity
◆ ~Entity()
|
virtualdefault |
Virtual destructor.
Member Function Documentation
◆ EntityID()
| std::size_t EntityID | ( | ) | const |
Get the unique ID value of this Entity.
◆ EntityReference()
| const std::shared_ptr<void>& EntityReference | ( | ) | const |
Get a reference-counting std::shared_ptr to the object inside the implementation that this object provides an abstraction for.
◆ FullIdentity()
| const Identity& FullIdentity | ( | ) | const |
Get the Identity object of this Entity.
◆ Interface() [1/2]
|
protected |
Get a pointer to the implementation of FeatureT.
This is a convenience function so that entities don't have to query for interfaces on their pimpl object.
- Returns
- A pointer to the implementation of FeatureT, or a nullptr if FeatureT is not available.
◆ Interface() [2/2]
|
protected |
Same as Interface(), but const-qualified so that const entities can request const-qualified interfaces from the implementation.
- Returns
- A pointer to a const-qualified implementation of F, or a nullptr if F is not available.
Member Data Documentation
◆ identity
|

This is a pointer to the physics engine implementation, and it can be used by the object features to find the interfaces that they need in order to function.
