MakerAlgConfig()

python.MakerAlgConfig.MakerAlgConfig	(		flags,
			acc,
			stream,
			file,
			clevel = D3PDMakerFlags.CompressionLevel,
			autoflush = D3PDMakerFlags.AutoFlush,
			ExistDataHeader = True,
		**	kw )

Configure algorithm for making a D3PD tree.

Each distinct D3PD tree is make by a separate algorithm.
This function is used to configure these algorithms.

Arguments:

  flags: The configuration flags.
  name: The name of the algorithm (required).
  stream: Athena stream for the tuple.
  file: Name of the file containing the tuple.
        If it starts with `pool:', then the tree is being emitted
        into a POOL file.  In that case, stream is just the name
        of the tree.
  clevel: Compresson level for the output ROOT file. By default it is
          controlled by the D3PDMakerFlags.CompressionLevel flag, but
          can be controlled D3PD-by-D3PD as well.
  autoflush: Allows overriding the global autoflush setting.
