## 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.
  Since:
    2.7
  See Also:
    `ByteArrayInputStream`
