Refrigerator Application Override APIs#

To override any of the following hooks, declare the corresponding *Impl() method in CustomerAppTask.h and implement it in CustomerAppTask.cpp. Ensure that the method signature matches its declaration in autogen/AppTaskImpl.h. The public Init() method maps to CabinetModeInitImpl() rather than InitImpl().

AppTask#


Override	Public API	Default behavior
`AppInitImpl`	`AppInit`	Registers the button callback and initializes the refrigerator.
`InitRefrigeratorImpl`	`InitRefrigerator`	Configures the refrigerator endpoint composition and semantic tags, and initializes the Temperature Control delegate.
`ButtonEventHandlerImpl`	`ButtonEventHandler`	Routes function-button events to the base application handler.
`DMPostAttributeChangeCallbackImpl`	`DMPostAttributeChangeCallback`	Handles attribute changes from the Refrigerator Alarm and Temperature Control clusters and monitors attribute changes from the Identify cluster.
`CabinetModeClusterInitImpl`	`CabinetModeClusterInit`	Constructs and initializes a `ModeBase::Instance` for the Cabinet Mode cluster on the refrigerator endpoint.
`CabinetModeInitImpl`	`Init`	Returns a success status. The Cabinet Mode delegate requires no additional initialization by default.
`HandleChangeToModeImpl`	`HandleChangeToMode`	Accepts the requested Cabinet Mode unless the request is for a direct transition between Normal and Rapid Freeze.
`GetModeLabelByIndexImpl`	`GetModeLabelByIndex`	Returns the supported Cabinet Mode label at the specified index.
`GetModeValueByIndexImpl`	`GetModeValueByIndex`	Returns the supported Cabinet Mode value at the specified index.
`GetModeTagsByIndexImpl`	`GetModeTagsByIndex`	Returns the semantic tags associated with the supported Cabinet Mode at the specified index.
