Examples of cascading.operation.Debug

cascading.operation.Debug
Class Debug is a {@link Filter} that will never remove an item from a stream, but will print the Tuple to eitherstdout or stderr.
Currently, if printFields is true, they will print every 10 Tuples.
The frequency that fields and tuples are printed can be set via {@link #setPrintFieldsEvery(int)} and{@link #setPrintTupleEvery(int)} methods, respectively.

    if( pipe instanceof Each && ( (Each) pipe ).getOperation() instanceof Debug )
      return pipe;


    String name = makeName( node, pipe );


    return new Each( pipe, debugLevel, new Debug( name, true ) );
    }
