org.technologybrewery.fermenter.stout.client.service.LocalOptimizationUtil.TransferObjectJsonOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

Enclosing class:

LocalOptimizationUtil

public class LocalOptimizationUtil.TransferObjectJsonOutputStream
extends com.gc.iotools.stream.os.OutputStreamToInputStream<Object>

Converts an OutputStream into an InputStream via an underlying Pipes implementation to prevent loading the entire object into memory for a TransferObject -> BusinessObject 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 TransferObject and streams that into a specific BusinessObject. Super obvious, right?
