Detailed Description

template<typename Target, typename T>
class gem5::Extension< Target, T >

This is the extension for carrying additional information.

Each type of extension will have a unique extensionID. This extensionID will assign to base class for comparsion.

Example usage:

class MyTarget : Extensible<MyTarget> {};

class MyExtension : public Extension<MyTarget, MyExtension> { public: MyExtension(); std::unique_ptr<ExtensionBase> clone() const override; uint32_t getData();

private: uint32_t data_;; };

std::unique_ptr<MyTarget> mytarget(new MyTarget); std::shared_ptr<MyExtension> myext(new MyExtension); mytarget->setExtension(myext);

std::shared_ptr<MyExtension> ext = mytarget->getExtension<MyExtension>(); uint32_t data = ext->getData(); mytarget->removeExtension<MyExtension>();

In the example above, MyTarget can carry an extension named MyExtension, which contains an additional data field. This could be applicated to any debug information or any data field in any protocol.
