Package com.spotify.zoltar

Interface ModelLoader.PreLoader<M extends Model<?>>

Type Parameters:

M - Model instance type.

All Superinterfaces:

AutoCloseable, Closeable, ModelLoader<M>

Enclosing interface:

ModelLoader<M extends Model<?>>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface ModelLoader.PreLoader<M extends Model<?>>
extends ModelLoader<M>

PreLoader is model loader that calls ModelLoader.get() allowing model preloading.

Returns a blocking ModelLoader. Blocks till the model is loaded or a Duration is met.

Type Parameters:

M - Underlying model instance.

Parameters:

supplier - model supplier.

duration - Amount of time that it should wait, if necessary, for model to be loaded.

executor - the executor to use for asynchronous execution.

Throws:

InterruptedException

ExecutionException

TimeoutException
