Member Function Documentation

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			const [inherited]

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			[inherited]

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

static void itk::LightObject::BreakOnError

(

)

[static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

virtual LightObject::Pointer itk::Object::CreateAnother

(

)

const [virtual, inherited]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

virtual void itk::Object::DebugOff

(

)

const [virtual, inherited]

Turn debugging output off.

virtual void itk::Object::DebugOn

(

)

const [virtual, inherited]

Turn debugging output on.

virtual void itk::LightObject::Delete

(

)

[virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

virtual const ParametersType& itk::SingleValuedNonLinearVnlOptimizer::GetCachedCurrentPosition

(

)

[virtual, inherited]

virtual const DerivativeType& itk::SingleValuedNonLinearVnlOptimizer::GetCachedDerivative

(

)

[virtual, inherited]

virtual const MeasureType& itk::SingleValuedNonLinearVnlOptimizer::GetCachedValue

(

)

[virtual, inherited]

Return Cached Values. These method have the advantage of not triggering a recomputation of the metric value, but it has the disadvantage of returning a value that may not be the one corresponding to the current parameters. For GUI update purposes, this method is a good option, for mathematical validation you should rather call GetValue().

Command* itk::Object::GetCommand

(

unsigned long

tag

)

[inherited]

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

virtual const CostFunctionType* itk::SingleValuedNonLinearOptimizer::GetCostFunction

(

)

[virtual, inherited]

Get the cost function.

CostFunctionAdaptorType* itk::SingleValuedNonLinearVnlOptimizer::GetCostFunctionAdaptor

virtual const ParametersType& itk::Optimizer::GetCurrentPosition

[static, inherited]

virtual const ParametersType& itk::Optimizer::GetInitialPosition

(

[virtual, inherited]

Get the position to initialize the optimization.

virtual const bool& itk::SingleValuedNonLinearVnlOptimizer::GetMaximize

(

)

[virtual, inherited]

Methods to define whether the cost function will be maximized or minimized. By default the VNL amoeba optimizer is only a minimizer. Maximization is implemented here by notifying the CostFunctionAdaptor which in its turn will multiply the function values and its derivative by -1.0.

const MetaDataDictionary& itk::Object::GetMetaDataDictionary

(

void

)

const [inherited]

Returns:

A constant reference to this objects MetaDataDictionary.

MetaDataDictionary& itk::Object::GetMetaDataDictionary

(

void

)

[inherited]

Returns:

A reference to this objects MetaDataDictionary.

Warning:

This reference may be changed.

const [inline, inherited]
