Detailed Description

template<unsigned int VOffsetDimension = 2>
class itk::Offset< VOffsetDimension >

Represent the offset between two n-dimensional indexes in a n-dimensional image.

Offset is a templated class to represent a multi-dimensional offset, i.e. (i,j,k,...). Offset is templated over the dimension of the space.

For the sake of efficiency, Offset does not define a default constructor, a copy constructor, or an operator=. We rely on the compiler to provide efficient bitwise copies.

Member Function Documentation

template<unsigned int VOffsetDimension = 2> void itk::Offset< VOffsetDimension >::Fill (  OffsetValueType  value  )  [inline]

Set one value for the offset in all dimensions. Useful for initializing an offset to zero. Definition at line 184 of file itkOffset.h.

template<unsigned int VOffsetDimension> Offset< VOffsetDimension > itk::Offset< VOffsetDimension >::GetBasisOffset (  unsigned int  dim  )  [static]

Return a basis vector of the form [0, ..., 0, 1, 0, ... 0] where the "1" is positioned in the location specified by the parameter "dim". Valid values of "dim" are 0, ..., VOffsetDimension-1. Definition at line 200 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> const OffsetValueType* itk::Offset< VOffsetDimension >::GetOffset (  void   )  const [inline]

Get the index. This provides a read only reference to the index. See also: SetOffset() Definition at line 168 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> unsigned int itk::Offset< VOffsetDimension >::GetOffsetDimension (   )  [inline, static]

Get the dimension (size) of the index. Definition at line 54 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> bool itk::Offset< VOffsetDimension >::operator!= (  const Self &  vec  )  const [inline]

Compare two offsets. Definition at line 146 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> const Self itk::Offset< VOffsetDimension >::operator+ (  const Size< VOffsetDimension > &  size  )  const [inline]

Add a size to an offset. Definition at line 73 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> const Self itk::Offset< VOffsetDimension >::operator+ (  const Self &  offset  )  const [inline]

Add an offset to an offset. Definition at line 62 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> const Self& itk::Offset< VOffsetDimension >::operator+= (  const Self &  vec  )  [inline]

Increment offset by an offset. Definition at line 115 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> const Self& itk::Offset< VOffsetDimension >::operator+= (  const Size< VOffsetDimension > &  size  )  [inline]

Increment index by a size. Definition at line 84 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> const Self itk::Offset< VOffsetDimension >::operator- (  const Self &  vec  )  [inline]

Subtract two offsets. Definition at line 104 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> const Self& itk::Offset< VOffsetDimension >::operator-= (  const Self &  vec  )  [inline]

Decrement offset by an offset. Definition at line 125 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> const Self& itk::Offset< VOffsetDimension >::operator-= (  const Size< VOffsetDimension > &  size  )  [inline]

Decrement index by a size. Definition at line 94 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> bool itk::Offset< VOffsetDimension >::operator== (  const Self &  vec  )  const [inline]

Compare two offsets. Definition at line 135 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> OffsetValueType itk::Offset< VOffsetDimension >::operator[] (  unsigned int  dim  )  const [inline]

Access an element of the index. Elements are numbered 0, ..., VOffsetDimension-1. This version can only be an rvalue. No bounds checking is performed. Definition at line 163 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> OffsetValueType& itk::Offset< VOffsetDimension >::operator[] (  unsigned int  dim  )  [inline]

Access an element of the offset. Elements are numbered 0, ..., VOffsetDimension-1. No bounds checking is performed. Definition at line 157 of file itkOffset.h.

template<unsigned int VOffsetDimension = 2> void itk::Offset< VOffsetDimension >::SetOffset (  const OffsetValueType  val[VOffsetDimension]  )  [inline]

Set the index. Try to prototype this function so that val has to point to a block of memory that is the appropriate size. See also: GetOffset() Definition at line 174 of file itkOffset.h.

Member Data Documentation

template<unsigned int VOffsetDimension = 2> OffsetValueType itk::Offset< VOffsetDimension >::m_Offset[VOffsetDimension]

Offset is an "aggregate" class. Its data is public (m_Offset) allowing for fast and convienent instantiations/assignments. The following syntax for assigning an index is allowed/suggested: Offset<3> index = {5, 2, 7}; Definition at line 192 of file itkOffset.h. Referenced by itk::Offset< VDimension >::operator-=(), and itk::Offset< VDimension >::operator==().
