Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class AbstractMeshReader< ELEMENT_DIM, SPACE_DIM >::NodeIterator

An iterator class for node data.

Todo:
#1930. We could roll most iterator functionality into a base class here

Definition at line 363 of file AbstractMeshReader.hpp.

Constructor & Destructor Documentation

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
AbstractMeshReader< ELEMENT_DIM, SPACE_DIM >::NodeIterator::NodeIterator ( unsigned  index,
AbstractMeshReader< ELEMENT_DIM, SPACE_DIM > *  pReader 
)
inline

Constructor for pointing to a specific item.

Note that, in the case of an ASCII mesh file, this will actually start wherever the file pointer currently is. The user is responsible for resetting the reader prior to creating an iterator.

Parameters
indexthe index of the item to point at
pReaderthe mesh reader to iterate over

Definition at line 377 of file AbstractMeshReader.hpp.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
AbstractMeshReader< ELEMENT_DIM, SPACE_DIM >::NodeIterator::NodeIterator ( const std::set< unsigned > &  rIndices,
AbstractMeshReader< ELEMENT_DIM, SPACE_DIM > *  pReader 
)

Constructor for iterating over a subset of the items in the mesh.

Parameters
rIndicesa set of item indices over which to iterate
pReaderthe mesh reader to iterate over

Definition at line 299 of file AbstractMeshReader.cpp.

Member Function Documentation

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void AbstractMeshReader< ELEMENT_DIM, SPACE_DIM >::NodeIterator::CacheData ( unsigned  index,
bool  firstRead = false 
)
private

Read the pointed-at item data (if we're pointing at anything) and cache it within the iterator, for use in dereference.

Parameters
indexthe item to read
firstReadSet to true in the constructor. This ensures that the line 0 is always read

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
const std::vector<double>& AbstractMeshReader< ELEMENT_DIM, SPACE_DIM >::NodeIterator::dereference ( ) const
inlineprivate

Dereference this iterator to get the data for the item pointed at.

Returns
reference Note that the returned reference is only valid for as long as this iterator is pointing at the item.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
bool AbstractMeshReader< ELEMENT_DIM, SPACE_DIM >::NodeIterator::equal ( const NodeIterator &  rOther) const
inlineprivate
Returns
true if two iterators point at the same item.
Parameters
rOtherthe other iterator

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
unsigned AbstractMeshReader< ELEMENT_DIM, SPACE_DIM >::NodeIterator::GetIndex ( ) const

Returns
the index of the item pointed at.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void AbstractMeshReader< ELEMENT_DIM, SPACE_DIM >::NodeIterator::increment ( )
private

Increment the iterator to point at the next item in the file.
