API ver. 2.6.30
There's not Ichimoku function in the IIndicator interface. It seem however, that one can use the calculateIndicator function to access the values as follow:
Object [] Ichimoku = indicators.calculateIndicator(instrument, period, new OfferSide[] {OfferSide.BID},
"ICHIMOKU", new IIndicators.AppliedPrice[]{IIndicators.AppliedPrice.CLOSE},
new Object[]{9, 26, 52}, Filter.WEEKENDS, 1, bidBar.getTime(), 0);

But even so, that method looks complicated and ugly(I didn't test it, so I don't know if it works).
Please add the Ichimoku function to IIndicator for easy access.
