GeezerVison is showing apache.github.io — FrameWriter (Apache SystemDS 3.4.0-SNAPSHOT API)

Package org.apache.sysds.runtime.io

Class FrameWriter

  • Direct Known Subclasses:

    public abstract class FrameWriter
extends Object
    Base class for all format-specific frame writers. Every writer is required to implement the basic write functionality but might provide additional custom functionality. Any non-default parameters (e.g., CSV read properties) should be passed into custom constructors. There is also a factory for creating format-specific writers.
