A class that represents accessor objects to iterators that don't make sense such as quad iterators in on 1d meshes. This class can not be used to create objects (it will in fact throw an exception if this should ever be attempted but it sometimes allows code to be written in a simpler way in a dimension independent way. For example, it allows to write code that works on quad iterators that is dimension independent because quad iterators (with the current class) exist and are syntactically correct. You can not expect, however, to ever generate one of these iterators, meaning you need to expect to wrap the code block in which you use quad iterators into something like if (dim>1)
– which makes eminent sense anyway.
This class provides the minimal interface necessary for Accessor classes to interact with Iterator classes. However, this is only for syntactic correctness, none of the functions do anything but generate errors.

Constructor. This class is used for iterators that make sense in a given dimension, for example quads for 1d meshes. Consequently, while the creation of such objects is syntactically valid, they make no semantic sense, and we generate an exception when such an object is actually generated.

InvalidAccessor< structdim, dim, spacedim >::InvalidAccessor | ( | const InvalidAccessor< structdim, dim, spacedim > & | i | ) |
Copy constructor. This class is used for iterators that make sense in a given dimension, for example quads for 1d meshes. Consequently, while the creation of such objects is syntactically valid, they make no semantic sense, and we generate an exception when such an object is actually generated.

InvalidAccessor< structdim, dim, spacedim >::InvalidAccessor | ( | const OtherAccessor & | ) |
Conversion from other accessors to the current invalid one. This of course also leads to a run-time error.

void InvalidAccessor< structdim, dim, spacedim >::copy_from | ( | const InvalidAccessor< structdim, dim, spacedim > & | ) |
Dummy copy operation.
Definition at line 436 of file tria_accessor.templates.h.
bool InvalidAccessor< structdim, dim, spacedim >::operator== | ( | const InvalidAccessor< structdim, dim, spacedim > & | ) | const |
Dummy comparison operators.
Definition at line 450 of file tria_accessor.templates.h.
void InvalidAccessor< structdim, dim, spacedim >::operator++ | ( | ) | const |
Dummy operators to make things compile. Does nothing.
Definition at line 507 of file tria_accessor.templates.h.
bool InvalidAccessor< structdim, dim, spacedim >::used | ( | ) | const |
Dummy function representing whether the accessor points to a used or an unused object.
Definition at line 479 of file tria_accessor.templates.h.
bool InvalidAccessor< structdim, dim, spacedim >::has_children | ( | ) | const |
Dummy function representing whether the accessor points to an object that has children.
