use of com.pushtorefresh.storio3.Interceptor.Chain in project storio by pushtorefresh.

the class ChainImpl method proceed.

// can be null on PreparedGetObject
@Nullable
@Override
public <Result, WrappedResult, Data> Result proceed(@NonNull PreparedOperation<Result, WrappedResult, Data> operation) {
    if (!interceptors.hasNext()) {
        throw new IllegalStateException("proceed was called on empty iterator");
    }
    calls++;
    // Confirm that this is the only call to chain.proceed().
    if (calls > 1) {
        throw new IllegalStateException("nextInterceptor " + interceptors.previous() + " must call proceed() exactly once");
    }
    // Call the nextChain nextInterceptor in the chain.
    final Interceptor nextInterceptor = interceptors.next();
    final ChainImpl nextChain = new ChainImpl(interceptors);
    return nextInterceptor.intercept(operation, nextChain);
}

Example 2 with Chain
