Class TextStream.TextReader

java.lang.Object
  java.io.Reader
      edu.upc.dama.dex.core.TextStream.TextReader

All Implemented Interfaces:

java.io.Closeable, java.lang.Readable

Enclosing class:

TextStream

public static class TextStream.TextReader
extends java.io.Reader

Reader implementation for TextStream.

This way we can use TextStream as a common Java Writer:

 long oid = ... // object OID
 long text = ... // TEXT attribute id
 dbg.getAttribute(oid, text, v);
 TextStream tstrm = v.getTextStream();
 StringBuffer sb = new StringBuffer();
 char[] buff = new char[200];
 int len = 0;
 BufferedReader br = new BufferedReader(new TextReader(tstrm));
 while ((len = br.read(buff, 0, 200)) != -1) {
     sb.append(buff, 0, len);
 }
 br.close(); // it already closes underlaying Reader and TextStream
