Class ByteArrayBuffer

java.lang.Object

Direct Known Subclasses:
StringBufferASCII, StringBufferLATIN1, StringBufferUTF8
public class ByteArrayBuffer extends AbstractArrayBuffer
This class is designed as a "scratchpad" for generating many byte arrays of unknown size. It will never shrink its internal buffer, so it should be disposed as soon as it is no longer needed.

Usage Example: 

 ByteArrayBuffer buf = new ByteArrayBuffer();
 List<byte[]> results = new ArrayList<>();
 for (Object obj : listOfThingsToProcess) {
     for (Object x : obj.thingsThatShouldBecomeBytes()) {
         buf.add(someCalculation(x));
     }
     results.add(buf.toArray());
     buf.clear();
 }
