When data or objects need to be shared between different objects due to the functional requirements of the application.

Participant

Flyweight (Translator)

-define the interface for sharing elements. Generally speaking, the parameters of the interface cannot be shared. Compared to sharing meta-stored data, it is called external data.

ConcreteFlyweight (ConcreTranslatorA,ConcreteTranslatorB)

-stores common or similar internal data.

-complete data composed of internal data and external data and realize the function of sharing meta-interface.

UnsharedConcreteFlyweight (-)

-there may be situations where there is no need to share data, both from the perspective of storage efficiency and from the perspective of application requirements. The interface of this class is the same as the share element, and can be used to manage the share meta-object.

FlyweightFactory (TranslatorFactory)

-build appropriate sharing elements according to the needs of users.

-decide whether to generate new shares or return shares that already exist and need to be shared according to pre-determined rules (whether to share or not, type).

Collaboration

The user acquires the sharing meta-object through FlywieghtFactory and invokes the operation of the sharing meta-object using external data as parameters to complete the function.
