Class ShortArrayBuffer

java.lang.Object
com.oracle.truffle.regex.tregex.buffer.AbstractArrayBuffer
com.oracle.truffle.regex.tregex.buffer.ShortArrayBuffer
All Implemented Interfaces:
Iterable<Integer>
public class ShortArrayBuffer extends AbstractArrayBuffer implements Iterable<Integer>
This class is designed as a "scratchpad" for generating many short 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: 

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