Detailed Description

Central manager for calculating apparent signatures of entities from various viewpoints.

This class encapsulates all the functionality for calculating the apparent signatures of entities in all the sensor domains. This is done by querying the VRF object state repository of the target entity for the absolute signature in the sensor domain, and then running a propagation model for that domain to correct the signature for the viewing location. Signature propagators are created from the DtSignaturePropagatorFactory based on the sensor domain specified in the original query.

private

Not implemented.

DtSensorSignatureManager::DtSensorSignatureManager ( DtPhysicalWorld *  physicalWorld )

protected

Protected to prevent uninitialized instances of DtSensorSignatureManager.

Call create() to instantiate a new DtSensorSignatreManager.

virtual

Member Function Documentation

DtSensorSignatureManager& DtSensorSignatureManager::operator= ( const DtSensorSignatureManager &  orig )

private

Not implemented.

virtual bool DtSensorSignatureManager::init ( )

protectedvirtual

Called by create() after constructor.

Returns

True on success.

static DtSensorSignatureManager* DtSensorSignatureManager::create ( DtPhysicalWorld *  physicalWorld )

static

Constructs a new instance, and calls init() on it.

Returns

A new instance of DtSensorSignatureManager, or NULL if init() fails.

virtual void DtSensorSignatureManager::reinitialize ( )

virtual

Resets any internals when scenario is closed.

virtual std::vector<DtString> DtSensorSignatureManager::sensorDomains ( ) const

virtual

Returns

Sensor domains

virtual double DtSensorSignatureManager::apparentObjectSignature ( const DtSymbolString &  sensorDomain, const DtSignaturePropagatorArgs &  propagatorArgs  ) const

virtual

Returns

The signature of the specified object as seen from the specified location, in the specified sensor domain. This may include effects such as drop off over range, terrain obscuration, etc. depending on the sensor domain and the DtSignaturePropagator used for this domain.

virtual double DtSensorSignatureManager::apparentObjectSignature ( const DtSymbolString &  sensorDomain, const DtVrfObject *  targetObject, const DtVrfObject *  viewingObject  ) const

virtual

Convenience function.

Creates a DtSignaturePropagatorArgs with the provided target and viewing object, and calls the above function.

virtual double DtSensorSignatureManager::apparentObjectSignature ( const DtSignaturePropagator *  propagator, const DtSymbolString &  sensorDomain, const DtSignaturePropagatorArgs &  propagatorArgs  ) const

virtual

Convenience function.

Allows you to pass in a custom propagator that a user created along with the arguments that they added. This does the same as apparentObjectSignature(const DtSymbolString& sensorDomain, const DtSignaturePropagatorArgs& propagatorArgs) const

virtual bool DtSensorSignatureManager::createPropagatorsFromDescriptorList ( const DtSignaturePropagatorDescriptorList &  descList )

virtual

Instantiates a new propagator for each sensor domain specified in the provided descriptor list using the DtSensorSignatureFactory and the types specified.

New propagators are put in mySignaturePropagatorMap indexed by domain.

Returns

true if all succeed.

virtual const DtSignaturePropagator* DtSensorSignatureManager::propagatorForDomain ( const DtSymbolString &  domain ) const

protectedvirtual

Returns the signature propagator for the specified domain by looking it up in mySignaturePropagatorMap.

If one is not found and cannot be created, returns NULL.

void DtSensorSignatureManager::deleteSignaturePropagators ( )

protected

Removes and deletes all propagators from mySignaturePropagatorMap.

Non-virtual because it is called from the destructor.
