Class ByteArrayChunkedIterator

java.lang.Object
  r01f.io.ByteArrayChunkedIterator

All Implemented Interfaces:

java.io.Closeable, java.util.Iterator<byte[]>, BytesChunkedIterator

public class ByteArrayChunkedIterator
extends java.lang.Object
implements BytesChunkedIterator

Abstrae al cliente de la lógica de iterar sobre un array de bytes para trocearlo en paquetes Esta clase es de utilidad por ejemplo cuando un churro de bytes hay que enviarlo en paquetes (chunks) por ejemplo a otro servidor (ej: subir ficheros a iw) De esta forma, el cliente se abstrae de la complejidad de implementar el troceado del churro de entrada Ejemplo de uso:

                R01MContentDataAPI contentDataAPI = R01MClientFactory.getContentDataAPI(_userCtx,contentOid);
                ChunkedIterator bytesIt = new ByteStreamChunkedIterator(is);    // cambiar por new ByteArrayChunkedIterator(fileBytes) si en lugar de un InputStream se pasa un array de bytes 
                while (bytesIt.hasNext()) {
                        int offset = bytesIt.getOffset();
                        byte[] bytes = bytesIt.next();
                        contentDataAPI.uploadAttachmentFileChunk(documentOid,path,bytes,offset);
                }
