Public Member Functions
template<typename DbTags >
Result	is_triggered (const db::DataBox< DbTags > &box) const noexcept
	Check whether the trigger fires.
template<typename DbTags >
bool	is_ready (const db::DataBox< DbTags > &box) const noexcept
	Check whether all data required to evaluate the trigger is available. The trigger is not responsible for checking whether dense output of the evolved variables is possible, but may need to check things such as the availability of FunctionOfTime data.

Detailed Description

Base class for checking whether to run an Event at arbitrary times.

The DataBox passed to the member functions will have Tags::Time, and therefore any compute tags depending on that value, set to the time to be tested. Any discrete properties of steps or slabs, such as the step size, may have the values from times off by one step. The evolved variables will be in an unspecified state.
