Detailed Description

template<class TNodeType>
class itk::SparseFieldLayer< TNodeType >

A very simple linked list that is used to manage nodes in a layer of a sparse field level-set solver.

This class implements a *very* simple linked list that is used to manage nodes in a layer of a sparse field level-set solver. For more information on the sparse field level-set solver, see documentation for itk::SparseFieldLevelSetImageFilter.

IMPORTANT!

One important and distinctive feature of this list implementation (in fact, the entire reason for this object's existance) is that no memory allocation/deallocation occurs during linking or unlinking of nodes. The nodes themselves are expected to carry the appropriate "Next" & "Previous" fields used to link. Guaranteeing that no calls to new or delete are *ever* made for normal list operations allows us to safely use this class in a multithread environment without incurring penalties from heap contention among threads. Because no allocation/deallocation occurs, it is entirely up to the calling program to manage the allocating and freeing of the list nodes.

Member Function Documentation

template<class TNodeType >

Iterator itk::SparseFieldLayer< TNodeType >::Begin

(

void

)

[inline]

Returns an iterator pointing to the first node in the list.

Definition at line 224 of file itkSparseFieldLayer.h.

template<class TNodeType >

ConstIterator itk::SparseFieldLayer< TNodeType >::Begin

(

void

)

const [inline]

Returns a const iterator pointing to the first node in the list.

Definition at line 229 of file itkSparseFieldLayer.h.

template<class TNodeType >

virtual::itk::LightObject::Pointer itk::SparseFieldLayer< TNodeType >::CreateAnother

(

void

)

const [virtual]

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::Object.

template<class TNodeType >

bool itk::SparseFieldLayer< TNodeType >::Empty

(

)

const [inline]

Returns TRUE if the list is empty, FALSE otherwise. Executes in constant time.

Definition at line 242 of file itkSparseFieldLayer.h.

template<class TNodeType >

Iterator itk::SparseFieldLayer< TNodeType >::End

(

void

)

[inline]

Returns an iterator pointing one node past the end of the list.

Definition at line 233 of file itkSparseFieldLayer.h.

template<class TNodeType >

ConstIterator itk::SparseFieldLayer< TNodeType >::End

(

void

)

const [inline]

Returns a const iterator pointing one node past the end of the list.

Definition at line 237 of file itkSparseFieldLayer.h.

template<class TNodeType >

NodeType* itk::SparseFieldLayer< TNodeType >::Front

(

)

[inline]

Returns a pointer to the first node in the list. Constant time.

Definition at line 190 of file itkSparseFieldLayer.h.

template<class TNodeType >

const NodeType* itk::SparseFieldLayer< TNodeType >::Front

(

)

const [inline]

Returns a const pointer to the first node in the list. Constant time.

Definition at line 194 of file itkSparseFieldLayer.h.

template<class TNodeType >

virtual const char* itk::SparseFieldLayer< TNodeType >::GetNameOfClass

(

)

const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::Object.

template<class TNodeType >

static Pointer itk::SparseFieldLayer< TNodeType >::New

(

)

[static]

Method for creation through the object factory.

Reimplemented from itk::Object.

[inline]

Unlinks the first node from the list. Constant time.

Definition at line 198 of file itkSparseFieldLayer.h.

template<class TNodeType >

virtual void itk::SparseFieldLayer< TNodeType >::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)		const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::Object.
