public class CharacterStreamWritingMessageHandler
extends org.springframework.integration.handler.AbstractMessageHandler
A MessageHandler that writes characters to a Writer. String, character array, and byte array payloads will be written directly, but for other payload types, the result of the object's IntegrationObjectSupport.toString() method will be written. To append a new-line after each write, set the shouldAppendNewLine flag to 'true'. It is 'false' by default.
