public interface ComponentEx extends Component {
    
Gets an iterator of implementations of the specified SPI.

 This method works as a kind of directory service for SPIs, allowing various components to define private contract and talk to each other. However unlike Component.getSPI(Class<Object>), this method can support cases where there is an ordered collection (defined by Iterable of implementations. The SPI contract should define whether lookups are for the first appropriate implementation or whether all returned implementations should be used. 
Returns: non-null Iterable of the SPI's provided by this object. Iterator may have no values.
