Class ByteArrayBuilder

java.lang.Object

com.healthmarketscience.jackcess.impl.ByteArrayBuilder

public class ByteArrayBuilder
extends java.lang.Object

Utility class for constructing byte[]s where the final size of the data is not known beforehand. The API is similar to ByteBuffer but the data is not actually written to a byte[] until toBuffer() or toArray() is called.
