Package org.apache.commons.io.input
Class UnsynchronizedByteArrayInputStream
java.lang.Object
java.io.InputStream
org.apache.commons.io.input.UnsynchronizedByteArrayInputStream
- All Implemented Interfaces:
Closeable
,AutoCloseable
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, see UnsynchronizedByteArrayInputStream.Builder
.
