Typed4EpoxyController

abstract class Typed4EpoxyController<T : Any!, U : Any!, V : Any!, W : Any!> : EpoxyController

This is a wrapper around com.airbnb.epoxy.EpoxyController to simplify how data is accessed. Use this if the data required to build your models is represented by four objects.

To use this, create a subclass typed with your data object. Then, call #setData whenever that data changes. This class will handle calling #buildModels with the latest data.

You should NOT call #requestModelBuild() directly.

Inherited Properties

defaultDiffingHandler	`static var defaultDiffingHandler: Handler!`
defaultModelBuildingHandler	`static var defaultModelBuildingHandler: Handler!`

Functions

buildModels	`fun buildModels(): Unit` `abstract fun buildModels(data1: T, data2: U, data3: V, data4: W): Unit`
moveModel	`open fun moveModel(fromPosition: Int, toPosition: Int): Unit`
requestDelayedModelBuild	`open fun requestDelayedModelBuild(delayMs: Int): Unit`
requestModelBuild	`fun requestModelBuild(): Unit`
setData	`open fun setData(data1: T, data2: U, data3: V, data4: W): Unit` Call this with the latest data when you want models to be rebuilt. The data will be passed on to `#buildModels(Object, Object, Object, Object)`

Inherited Functions

add	`open fun add(model: EpoxyModel<>): Unit` Add the model to this controller. Can only be called from inside . `open fun add(vararg modelsToAdd: EpoxyModel<>!): Unit` `open fun add(modelsToAdd: MutableList<out EpoxyModel<*>!>): Unit` Add the models to this controller. Can only be called from inside .
addInterceptor	`open fun addInterceptor(interceptor: EpoxyController.Interceptor): Unit` Add an interceptor callback to be run after models are built, to make any last changes before they are set on the adapter. Interceptors are run in the order they are added.
addModelBuildListener	`open fun addModelBuildListener(listener: OnModelBuildFinishedListener!): Unit` Add a listener that will be called every time `#buildModels()` has finished running and changes have been dispatched to the RecyclerView.
cancelPendingModelBuild	`open fun cancelPendingModelBuild(): Unit` Cancels a pending call to `#buildModels()` if one has been queued by .
getAdapter	`open fun getAdapter(): EpoxyControllerAdapter` Get the underlying adapter built by this controller. Use this to get the adapter to set on a RecyclerView, or to get information about models currently in use.
getModelCountBuiltSoFar	`open fun getModelCountBuiltSoFar(): Int` Get the number of models added so far during the `#buildModels()` phase. It is only valid to call this from within that method.
getSpanCount	`open fun getSpanCount(): Int`
getSpanSizeLookup	`open fun getSpanSizeLookup(): SpanSizeLookup` For use with a grid layout manager - use this to get the `SpanSizeLookup` for models in this controller. This will delegate span look up calls to each model's . Make sure to also call `#setSpanCount(int)` so the span count is correct.
hasPendingModelBuild	`open fun hasPendingModelBuild(): Boolean` Whether an update to models is currently pending. This can either be because `#requestModelBuild()` was called, or because models are currently being built or diff on a background thread.
isBuildingModels	`open fun isBuildingModels(): Boolean` True if the current callstack originated from the buildModels call, on the same thread.
isDebugLoggingEnabled	`open fun isDebugLoggingEnabled(): Boolean`
isDuplicateFilteringEnabled	`open fun isDuplicateFilteringEnabled(): Boolean`
isMultiSpan	`open fun isMultiSpan(): Boolean`
isStickyHeader	`open fun isStickyHeader(position: Int): Boolean` Called to check if the item at the position is a sticky item, by default returns false. The sub-classes should override the function if they are using sticky header feature.
notifyModelChanged	`open fun notifyModelChanged(position: Int): Unit` An way to notify the adapter that a model has changed. This is intended to be used with `androidx.recyclerview.widget.ItemTouchHelper` to allow revert swiping a model.
onAttachedToRecyclerView	`open fun onAttachedToRecyclerView(recyclerView: RecyclerView): Unit` Called when the controller's adapter is attach to a recyclerview.
onDetachedFromRecyclerView	`open fun onDetachedFromRecyclerView(recyclerView: RecyclerView): Unit` Called when the controller's adapter is detached from a recyclerview.
onExceptionSwallowed	`open fun onExceptionSwallowed(exception: RuntimeException): Unit` This is called when recoverable exceptions occur at runtime. By default they are ignored and Epoxy will recover, but you can override this to be aware of when they happen.
onModelBound	`open fun onModelBound(holder: EpoxyViewHolder, boundModel: EpoxyModel<>, position: Int, previouslyBoundModel: EpoxyModel<>?): Unit` Called immediately after a model is bound to a view holder. Subclasses can override this if they want alerts on when a model is bound. Alternatively you may attach a listener directly to a generated model with model.onBind(...)
onModelUnbound	`open fun onModelUnbound(holder: EpoxyViewHolder, model: EpoxyModel<*>): Unit` Called immediately after a model is unbound from a view holder. Subclasses can override this if they want alerts on when a model is unbound. Alternatively you may attach a listener directly to a generated model with model.onUnbind(...)
onRestoreInstanceState	`open fun onRestoreInstanceState(inState: Bundle?): Unit`
onSaveInstanceState	`open fun onSaveInstanceState(outState: Bundle): Unit`
onViewAttachedToWindow	`open fun onViewAttachedToWindow(holder: EpoxyViewHolder, model: EpoxyModel<*>): Unit` Called when the given viewholder is attached to the window, along with the model it is bound to.
onViewDetachedFromWindow	`open fun onViewDetachedFromWindow(holder: EpoxyViewHolder, model: EpoxyModel<*>): Unit` Called when the given viewholder is detechaed from the window, along with the model it is bound to.
removeInterceptor	`open fun removeInterceptor(interceptor: EpoxyController.Interceptor): Unit` Remove an interceptor that was added with `#addInterceptor(Interceptor)`.
removeModelBuildListener	`open fun removeModelBuildListener(listener: OnModelBuildFinishedListener!): Unit` Remove a listener added with `#addModelBuildListener(OnModelBuildFinishedListener)`. This is safe to call from inside the callback `OnModelBuildFinishedListener#onModelBuildFinished(DiffResult)`
setDebugLoggingEnabled	`open fun setDebugLoggingEnabled(enabled: Boolean): Unit` If enabled, DEBUG logcat messages will be printed to show when models are rebuilt, the time taken to build them, the time taken to diff them, and the item change outcomes from the differ. The tag of the logcat message is the class name of your EpoxyController.
setFilterDuplicates	`open fun setFilterDuplicates(filterDuplicates: Boolean): Unit` If set to true, Epoxy will search for models with duplicate ids added during and remove any duplicates found. If models with the same id are found, the first one is left in the adapter and any subsequent models are removed. will be called for each duplicate removed.
setGlobalDebugLoggingEnabled	`open static fun setGlobalDebugLoggingEnabled(globalDebugLoggingEnabled: Boolean): Unit` Similar to `#setDebugLoggingEnabled(boolean)`, but this changes the global default for all EpoxyControllers.
setGlobalDuplicateFilteringDefault	`open static fun setGlobalDuplicateFilteringDefault(filterDuplicatesByDefault: Boolean): Unit` `#setFilterDuplicates(boolean)` is disabled in each EpoxyController by default. It can be toggled individually in each controller, or alternatively you can use this to change the default value for all EpoxyControllers.
setGlobalExceptionHandler	`open static fun setGlobalExceptionHandler(globalExceptionHandler: EpoxyController.ExceptionHandler): Unit` Set a callback to be notified when a recoverable exception occurs at runtime. By default these are ignored and Epoxy will recover, but you can override this to be aware of when they happen.
setSpanCount	`open fun setSpanCount(spanCount: Int): Unit` If you are using a grid layout manager you must call this to set the span count of the grid. This span count will be passed on to the models so models can choose which span count to be.
setupStickyHeaderView	`open fun setupStickyHeaderView(stickyHeader: View): Unit` Optional callback to setup the sticky view, by default it doesn't do anything. The sub-classes should override the function if they are using sticky header feature.
teardownStickyHeaderView	`open fun teardownStickyHeaderView(stickyHeader: View): Unit` Optional callback to perform tear down operation on the sticky view, by default it doesn't do anything. The sub-classes should override the function if they are using sticky header feature.
