Create a protocol buffer multirequest with NO data for a list of actions (data is carried otherwise than via protobuf). This means it just notes attributes, whether to write the WAL, etc., and the presence in protobuf serves as place holder for the data which is coming along otherwise. Note that Get is different. It does not contain 'data' and is always carried by protobuf. We return references to the data by adding them to the passed in data param.

Propagates Actions original index.

Parameters:

regionName -

actions -

cells - Place to stuff references to actual data.

Returns:

a multi request that does not carry any data.

Throws:

IOException
