CorrelatorConfiguration (SSS Models)

Getting an Instance
Clients are discouraged from creating new instances of this type by using the constructors of concrete subclasses. The preferred way to get an instance of this type is to use the static factory method, makeFor(CorrelatorName, AntennaElectronics). The static method getSupportedCorrelators() lists the correlator supported by this configuration class.

Working with Basebands and Baseband Pairs
This configuration now has only one method for fetching basebands: getBasebands(). The method getBasebandPairs() has been eliminated, but the CorrelatorBaseband now has methods to determine whether or not it is part of pair and, if so, who its parter is. The basebands held by this configuration were originally constructed based on the output signals of the AntennaElectronics provided to the factory method.

Listening for Changes
This configuration gives clients the ability to listen for changes in the collection of basebands in this configuration. Clients may register by using the addBasebandCollectionListener method. Registered users will be notified when a baseband(s) is added to the configuration, removed from the configuration, or both at once. Note that a listener's basebandCollectionChanged method is called only when the collection itself changes, not when properties of the contained basebands change.

Field Summary
`protected List<CorrelatorBasebandAbs>`	`activeBBs` The basebands of this configuration.
`protected List<BasebandCollectionListener>`	`bbListeners` Objects interested in changes to our collection of basebands.
`protected Map<String,CorrelatorBasebandAbs>`	`inactiveBBs` Basebands that had been, but are not currently, active.
`protected AntennaElectronics`	`signalSource` The provider of digital signals for the basebands of this configuration.

Constructor Summary
`protected`	`CorrelatorConfiguration()`
`protected`	`CorrelatorConfiguration(AntennaElectronics signalSrc)` Constructs a new configuration that is initialized from `signalSrc`.

Method Summary
`void`	`addBasebandCollectionListener(BasebandCollectionListener newListener)` Registers a new listener that will be notified whenever the collection of basebands in this configuration is changed.
`void`	`clearId()` Resets this instance's ID, and the IDs of all its components, to a value that represents the unidentified state.
`CorrelatorConfiguration`	`clone()` Returns a copy of this configuration.
`protected void`	`createdBasebandsFromPersistentStore()` Called after basebands were created from a persistent store, such as a database or XMl file.
`boolean`	`equals(Object o)` Returns true if `o` is equal to this configuration.
`List<CorrelatorBaseband>`	`getBasebands()` Returns the basebands of this correlator configuration.
`Long`	`getId()`
`protected List<CorrelatorBaseband>`	`getOrderedBasebands()` Allows concrete subclasses to be in charge of the ordering of the basebands returned by `getBasebands()`.
`AntennaElectronics`	`getSignalSource()` Returns the source of input signals for this configuration, if any.
`static List<CorrelatorName>`	`getSupportedCorrelators()` Returns a list of the correlators that are supported by the `factory method` of this class.
`BackendType`	`getType()` Creates and initializes the active basebands for this configuration based on the antenna electronics that were sent to the constructor.
`int`	`hashCode()` Returns a hash code value for this configuration.
`protected abstract CorrelatorBaseband`	`makeBasebandFrom(DigitalSignal ds)` Creates a new baseband from the given digital signal.
`protected abstract CorrelatorBaseband`	`makeBasebandFrom(DigitalSignal ds1, DigitalSignal ds2)` Creates a new baseband from the given digital signals.
`static CorrelatorConfiguration`	`makeFor(CorrelatorName correlator, AntennaElectronics signalSrc)` Creates and returns a new configuration for the given correlator that is initialized from `signalSrc`.
`void`	`removeBasebandCollectionListener(BasebandCollectionListener formerListener)` Removes `formerListener` from this configuration's list of baseband collection listeners.
`void`	`setId(Long id)` Sets the ID of this object; not recommended for most clients.
`void`	`setSignalSource(AntennaElectronics newSource)` Sets the source of input signals for this configuration.
