Detailed Description

template<class MT>
class libMesh::MeshInput< MT >

This class defines an abstract interface for Mesh input. Specific classes derived from this class actually implement reading various mesh formats.

Constructor & Destructor Documentation

template<class MT >
libMesh::MeshInput< MT >::MeshInput ( bool  is_parallel_format = false)
inlineexplicitprotected

Default constructor. Will set the _obj to NULL, effectively rendering this object useless.

Definition at line 126 of file mesh_input.h.

126  :
128  _obj (NULL),
129  _is_parallel_format(is_parallel_format)
130 {
131 }
template<class MT>
libMesh::MeshInput< MT >::MeshInput ( MT &  obj,
const bool  is_parallel_format = false 
)
inlineexplicitprotected

Constructor. Takes a writeable reference to an object. This is the constructor required to read an object.

Member Data Documentation

template<class MT>
const bool libMesh::MeshInput< MT >::_is_parallel_format
private

Flag specifying whether this format is parallel-capable. If this is false (default) I/O is only permitted when the mesh has been serialized.

Definition at line 117 of file mesh_input.h.

Referenced by libMesh::MeshInput< MT >::MeshInput().

template<class MT>
MT* libMesh::MeshInput< MT >::_obj
private

A pointer to a non-const object object. This allows us to read the object from file.

Definition at line 110 of file mesh_input.h.

template<class MT>
std::vector<bool> libMesh::MeshInput< MT >::elems_of_dimension
protected

A vector of bools describing what dimension elements have been encountered when reading a mesh.
