Examples of org.apache.cassandra.io.util.FastByteArrayOutputStream

org.apache.cassandra.io.util.FastByteArrayOutputStream
A specialized {@link OutputStream} for class for writing content to an(internal) byte array. As bytes are written to this stream, the byte array may be expanded to hold more bytes. When the writing is considered to be finished, a copy of the byte array can be requested from the class. @see ByteArrayOutputStream
