Detailed Description
This file contains utility classes to instantiate commands when they are received from the network, or reloaded after a crash.
For each command, a factory will be generated and stored in a map with the command name, to allow fast instantiation upon command reception.
Each command has two identifiers :
- One is the CommandGroupKey used to differentiate groups of commands
- One is the CommandKey used to differentiate commands in a same group
They are stored in a CommandData upon serialization, along with the command-specific data.
Reinstantiation is done through score::ApplicationContext::instantiateUndoCommand.
OPTIMIZEME: right now the names are used, it should be nice to migrate towards uids. OPTIMIZEME : maybe we could just concatenate both keys and have a single hash_map...

Typedef Documentation
◆ CommandFactory
| using CommandFactory = score::Command* (*)(const QByteArray&) |
Base factory for commands.
Base typedef for command instantiation. Allows a polymorphic use.
◆ CommandGeneratorMap
| using CommandGeneratorMap = std::vector<std::pair<CommandKey, CommandFactory> > |
The CommandGeneratorMap struct.
A map between command names and corresponding factories.
