Confuse on setting spout name and get topology name in Trident topology

[vlhf刘海峰]

Hi,

I tried to use name() method to name the nodes in a trident topology, and I saw 
the generated bolts then has a name like b{N}-{name} in storm UI, but the spout 
was still shown as spout0. How to name the spout node?

Another question, in trident topology, via context.getStormId I can get the 
topology id, but is there any API to get the topology name?

Thanks
