An inductor is an energy storage device. We normally use an inductor for its capability to provide an increased output voltage (when the magnetic field collapses) and we say it provides a voltage source (an increased voltage source). At the same time it is providing a current source, but this current source is less than the input current to the circuit, so we normally neglect this feature as it is not an "improvement." However any output from an inductor includes a certain amount of current and this may be what is being referred to.
When an inductor is used as a filter to reduce spikes, the output consists of a voltage and a current. The inductor is only modifying the voltage by reducing the ripple (spikes). It does not change the value of current.
