Using data feed name and line name in Indicator

[momentum]

Hi,

I wonder whether I can use the data feed name and the line name passed as parameters within the Indicator class to retrieve the corresponding line.

In a Strategy class I can do for example

self.getdatabyname(self.params.data_name)._getline(self.params.line_name)

I understand that I could pass either the actual data/line or data and line indices but I wonder whether there is something similar to the above for the indicator class.

Thanks

Indicators can take anything as a data feed, including other indicators and temporary line buffers created out of (for example) arithmetic operations, which of course immediately forbids something like getdatabyname
