Class KriptonXLiveDataHandlerImpl<T>

java.lang.Object

com.abubusoft.kripton.androidx.livedata.KriptonXLiveDataHandlerImpl<T>

Type Parameters:

T - The type of the live data

All Implemented Interfaces:

LiveDataHandler

public abstract class KriptonXLiveDataHandlerImpl<T>
extends Object
implements LiveDataHandler

A LiveData class that can be invalidated & computed when there are active observers.

It can be invalidated via invalidate(), which will result in a call to compute() if there are active observers (or when they start observing)

This is an internal class for now, might be public if we see the necessity.

Constructor Detail

KriptonXLiveDataHandlerImpl

public KriptonXLiveDataHandlerImpl()

Creates a computable live data that computes values on the arch IO thread executor.

KriptonXLiveDataHandlerImpl

public KriptonXLiveDataHandlerImpl(@NonNull
                                   Executor executor)

Creates a computable live data that computes values on the specified executor.

Parameters:

executor - Executor that is used to compute new LiveData values.

Method Detail

getLiveData

@NonNull
public KriptonXLiveData<T> getLiveData()

Returns the LiveData managed by this class.

Returns:

A LiveData that is controlled by ComputableLiveData.

invalidate

public void invalidate()

Invalidates the LiveData.

When there are active observers, this will trigger a call to compute().

Specified by:

invalidate in interface LiveDataHandler
