All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

Enclosing class:

LocalOptimizationUtil

public class LocalOptimizationUtil.BusinessObjectJsonOutputStream
extends com.gc.iotools.stream.os.OutputStreamToInputStream<ValueServiceResponse<TransferObject>>

Converts an OutputStream into an InputStream via an underlying Pipes implementation to prevent loading the entire object into memory for a ValueServiceResponse -> ValueServiceResponse transformation. See EasyStream documentation for more (somewhat confusing) information (but better than doing it all by hand). Bottom line - this takes an InputStream of JSON representing a specific ValueServiceResponse with BusinessObject(s) and streams that into a specific ValueServiceResponse with TransferObject(s). Super obvious, right?
