Package org.apache.beam.sdk.fn.stream

Class DataStreams.ElementDelimitedOutputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    Enclosing class:
    DataStreams
    public static final class DataStreams.ElementDelimitedOutputStream
extends java.io.OutputStream
    An adapter which wraps an DataStreams.OutputChunkConsumer as an OutputStream.

    Note that this adapter follows the Beam Fn API specification for forcing values that encode producing zero bytes to produce exactly one byte.

    Note that users must invoke delimitElement() at each element boundary.
