Public methods

MutableStub

public static final @NonNull MutableStub<Object, @NonNull R> <R extends Object> MutableStub(@NonNull Throwable defaultError)

Creates a new MutableStub that throws an exception if the queue is empty.

Consider passing a default handler instead, so the exception is not created until necessary:

MutableStub { throw Exception() }
Parameters
@NonNull Throwable defaultError

The exception to throw if the queue is empty.

MutableStub

public static final @NonNull MutableStub<Object, @NonNull R> <R extends Object> MutableStub(R defaultResponse)

Creates a new MutableStub with a default return value used when the queue is empty.

Parameters
R defaultResponse

The default return value

buildStub

public static final @NonNull Stub<@NonNull T, @NonNull R> <T extends Object, R extends Object> buildStub(
    @NonNull Function1<@NonNull MutableStub<@NonNull T, @NonNull R>, Unit> builder
)

enqueue

public static final void <R extends Object> enqueue(
