Class ObjectArrayBuffer

java.lang.Object

com.oracle.truffle.regex.tregex.buffer.AbstractArrayBuffer

com.oracle.truffle.regex.tregex.buffer.ObjectArrayBuffer

All Implemented Interfaces:

Iterable<Object>

public final class ObjectArrayBuffer
extends AbstractArrayBuffer
implements Iterable<Object>

This class is designed as a "scratchpad" for generating many Object 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:

 SomeClass[] typedArray = new SomeClass[0];
 ObjectArrayBuffer buf = new ObjectArrayBuffer();
 List results = new ArrayList<>();
 for (Object obj : listOfThingsToProcess) {
     for (Object x : obj.thingsThatShouldBecomeSomeClass()) {
         buf.add(someCalculation(x));
     }
     results.add(buf.toArray(typedArray));
     buf.clear();
 }
