public interface ICSDeviceFeatures

The CSDeviceBasedInterpreter may do some unnecessary work when interfacing to an ICSDevice, for example when he realizes images where the device finally only handles shapes or text.

This optional interface can signal to the interpreter that it is not interested in some of the arguments in the ICSDevice callback. Only the arguments are replaced with null, the callback itself is performed to support lightweight implementations that for example only rely on the object name.

This declarative interface is designed to fine tune the CSDeviceBasedInterpreter where either a PDF object lookup or other complex object construction is involved. Where this tuning is not enough you may be better off subclassing CSInterpreter directly.
