DocCollection

public DocCollection(String name,
             Map<String,Slice> slices,
             Map<String,Object> props,
             DocRouter router,
             int zkVersion,
             String znode)

Parameters:

name - The name of the collection

slices - The logical shards of the collection. This is used directly and a copy is not made.

props - The properties of the slice. This is used directly and a copy is not made.
