Detailed Description

Main Xronos SDK namespace.

Typedef Documentation

InvalidNameError

using xronos::sdk::InvalidNameError = abi::InvalidNameError

Exception that is thrown when creating an element with an invalid name.

A name is invalid if it is empty, if it contains whitespace or any of . , / * $ ? # @, or if it is already in use within the same container.

Enumeration Type Documentation

TriggerStatus

enum class xronos::sdk::TriggerStatus : std::uint8_t

strong

The outcome of a PhysicalEvent trigger attempt.

• TriggerStatus::Accepted: the runtime accepted the event and it is queued for processing.
• TriggerStatus::NotStarted: the application has not started yet and the event was dropped.
• TriggerStatus::Stopped: the application has stopped and the event was dropped.
• TriggerStatus::Unknown: the implementation reported a status this SDK version does not recognize; the event was dropped.
