Member Function Documentation

apply()

virtual optional< LightColorValues > esphome::light::LightTransformer::apply ( )

pure virtual

This will be called while the transformer is active to apply the transition to the light.

Can either write to the light directly, or return LightColorValues that will be applied.

Implemented in esphome::light::AddressableLightTransformer, esphome::light::LightFlashTransformer, and esphome::light::LightTransitionTransformer.

get_progress_()

float esphome::light::LightTransformer::get_progress_ ( )

inlineprotected

The progress of this transition, on a scale of 0 to 1.

Definition at line 45 of file light_transformer.h.

get_start_values()

const LightColorValues & esphome::light::LightTransformer::get_start_values ( ) const

inline

Definition at line 35 of file light_transformer.h.

get_target_values()

const LightColorValues & esphome::light::LightTransformer::get_target_values ( ) const

inline

Definition at line 37 of file light_transformer.h.

is_finished()

virtual bool esphome::light::LightTransformer::is_finished ( )

inlinevirtual

Indicates whether this transformation is finished.

Reimplemented in esphome::light::LightFlashTransformer.

start()

virtual void esphome::light::LightTransformer::start ( )

inlinevirtual

This will be called before the transition is started.

Reimplemented in esphome::light::AddressableLightTransformer, esphome::light::LightFlashTransformer, and esphome::light::LightTransitionTransformer.

Definition at line 26 of file light_transformer.h.

stop()

virtual void esphome::light::LightTransformer::stop ( )

inlinevirtual

This will be called after transition is finished.

Reimplemented in esphome::light::LightFlashTransformer.
