Macro Definition Documentation

DEFINE_SET_DATA_ACTION

#define DEFINE_SET_DATA_ACTION	(		xName,
			xActionName,
			xActionDesc,
			xDataType,
			xAttributeName,
			xAttributeType,
			xOperatorBlock
	)

Macro DEFINE_SET_DATA_ACTION defines an action that sets an attribute from the configuration.

Parameters

xName	type identifier for action
xActionName	string identifier of action (lowercase)
xActionDesc	string description of action
xDataType	type identifier for member data pointer
xAttributeName	string identifier of the attribute (defines configuration)
xAttributeType	type identifier of the attribute
xOperatorBlock	code block that makes use of ptr_ and value_

Example

Given the type SimulationSync and the action "modify the simulation speed", we can create it in code like so:

DEFINE_SET_DATA_ACTION(RealtimeFactor, "realtime_factor", "modify simulation speed",
                       SimulationSync, "factor", double,
                       {
                        logger()->info("Setting target simulation speed: {}", value_);
                        ptr_->set_realtime_factor(value_);
                       })

This will define the following classes for us:

• RealtimeFactor
• RealtimeFactorFactory

This action can be registered with the register_action helper function. Refer to doc/reference/actions.rst for the configuration.

DEFINE_SET_STATE_ACTION

#define DEFINE_SET_STATE_ACTION	(		xName,

			xState,
			xOperatorBlock
	)

Macro DEFINE_SET_STATE_ACTION defines an action that has only a single state and no configuration.

Parameters

xName	type identifier for event
xname	string identifier of event (lowercase)
xdescription	string description of event
xState	type identifier for member state pointer
xOperatorBlock	code block that makes use of ptr_

Example

Given the type Simulation and the action "abort the simulation", we can create it in code like so, note that the semicolon at the end is required.

DEFINE_SET_STATE_ACTION(Abort, "abort", "abort simulation", Simulation, {
  ptr_->abort();
});

This will define the following classes for us:

• Abort
• AbortFactory

This action can be registered with the register_action helper function.
