\brief Base class for a plugin
Example of how to declare a new plugin :
\code{.cpp}
// necessary headers
#include "utils/plugins/plugin_interface.h"
#include "utils/plugins/plugin_base.hpp"
#include "utils/plugins/module_base.hpp"
// First declare the plugin
class ExamplePlugin: public specmicp::plugins::PluginBase
{
public:
ExamplePlugin():
PluginBase()
{
// set required version
set_api_version(0, 1, 0);
}
~ExamplePlugin() = default // The destructor can be used to free memory if needed
bool initialize(const specmicp::plugins::PluginManagerServices& services) override
{
// register a new module
auto test_module = specmicp::plugins::ModuleBase::create_module();
auto retcode = services.register_module("test_module", std::move(test_module));
if (not retcode) {
return false;
}
// register a new object
auto factory = []() {return new TestObject();
};
retcode = services.register_object("test_module", "test_object", factory);
if (not retcode) {
return false;
}
return true;
}
};
// Then we register the plugin
SPECMICP_PLUGIN(BasicPlugin);
\endcode
