These are supporting class types for etl::intrusive_timer.

timer_config

class timer_config

Description
Contains the configuration for a timer.

---

ETL_CONSTEXPR timer_config(uint32_t interval, etl::timer::mode::type mode) ETL_NOEXCEPT

Description
Constructs a timer configuration.

Parameters
uint32_t interval : The initial interval for the timer. etl::timer::mode::type mode : The initial mode of the timer.

---

ETL_CONSTEXPR uint32_t get_interval() const ETL_NOEXCEPT

Description
Returns the interval of the timer.

---

ETL_CONSTEXPR etl::timer::mode::type get_mode() const ETL_NOEXCEPT

Description
Returns the mode of the timer.
etl::timer::mode::No_Mode_Set
etl::timer::mode::Single_Shot
etl::timer::mode::Repeating

---

ETL_CONSTEXPR etl::timer::id::type get_id() const ETL_NOEXCEPT

Description
Returns the id of the timer.
The timer ID is set by registering a node that contains this configuration with an etl::intrusive_timer.

---

ETL_CONSTEXPR14 void clear() ETL_NOEXCEPT

Description
Clears the timer configuration.
Interval = etl::timer::interval::No_Active_Interval
Mode = etl::timer::mode::No_Mode_Set
ID = etl::timer::id::No_Timer

timer_node

class timer_node

Description
Base class for all timer nodes.

---

timer_node(const timer_config& config_) ETL_NOEXCEPT

Description
Construct from an etl::timer_config.

---

timer_node(const timer_node& node_) ETL_NOEXCEPT

Description
Copy constructor.

---

const timer_config& get_config() const ETL_NOEXCEPT

Description
Returns the configuration of the timer.

---

ETL_CONSTEXPR uint32_t get_delta() const ETL_NOEXCEPT

Description
Returns the delta of the timer.

---

ETL_CONSTEXPR uint32_t get_interval() const ETL_NOEXCEPT

Description
Returns the interval of the timer.

---

ETL_CONSTEXPR etl::timer::mode::type get_mode() const ETL_NOEXCEPT

Description
Returns the mode of the timer.
etl::timer::mode::No_Mode_Set
etl::timer::mode::Single_Shot
etl::timer::mode::Repeating

---

ETL_CONSTEXPR etl::timer::id::type get_id() const ETL_NOEXCEPT

Description
Returns the id of the timer.

---

static etl::timer_node* end() ETL_NOEXCEPT

Description
Returns a pointer to the static sentinel timer node used to mark the end of the intrusive timer lists.

timer_callback_node

template <typename TCallback>
class timer_callback_node : public etl::timer_node

Description
A timer node for a function callback using etl::delegate, etl::inplace_function, or similar.
Derived from etl::timer_node.

timer_message_node

template <typename TMessage>
class timer_message_node : public etl::timer_node

Description
A timer node for a message callback using an etl::message derived object.
Derived from etl::timer_node.
Static asserts if TMessage is not derived from etl::imessage.
