# Class UnsynchronizedByteArrayInputStream

java.lang.Object
java.io.InputStream
org.apache.commons.io.input.UnsynchronizedByteArrayInputStream

All Implemented Interfaces:
  `Closeable`, `AutoCloseable`

public class UnsynchronizedByteArrayInputStream extends InputStream
This is an alternative to `ByteArrayInputStream` which removes the synchronization overhead for non-concurrent access; as such this class is not thread-safe.

To build an instance, use `UnsynchronizedByteArrayInputStream.Builder`.

Since:
  2.7
