Class BAAInputStream

java.lang.Object

java.io.InputStream

org.apache.axiom.attachments.utils.BAAInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class BAAInputStream
extends java.io.InputStream

BAAInputStream is like a ByteArrayInputStream. A ByteArrayInputStream stores the backing data in a byte[]. BAAInputStream stores the backing data in a Array of byte[]. Using several non-contiguous chunks reduces memory copy and resizing.
