Detailed Description

template<typename T = Number>
class libMesh::ParameterAccessor< T >

Base class for reading/writing sensitivty parameters.

Accessor object allowing reading and modification of the independent variables in a parameter sensitivity calculation.

This is an abstract base class. Derived objects may simply modify the parameter value at some address in memory, or may call arbitrary setter/getter functions.

Member Function Documentation

template<typename T = Number>
virtual UniquePtr<ParameterAccessor<T> > libMesh::ParameterAccessor< T >::clone ( ) const
pure virtual

Returns a new copy of the accessor. The new copy should probably be as shallow as possible, but should still access the same parameter.

Implemented in libMesh::ParameterMultiAccessor< T >, libMesh::ParameterMultiPointer< T >, libMesh::ParsedFEMFunctionParameter< T >, libMesh::ParsedFunctionParameter< T >, and libMesh::ParameterPointer< T >.

Proxy: for backward compatibility, we allow codes to treat a ParameterAccessor as if it were a simple pointer-to-value. We can't safely allow "Number * n = parameter_vector[p]" to compile, but we can allow "*parameter_vector[p] += deltap" to work.

virtual ParameterAccessor<T>& libMesh::ParameterAccessor< T >::operator= ( T *  )

Reseater: change the location of the parameter we access. This is included for backward compatibility, but will be deprecated in some classes and not implemented in others.

Reimplemented in libMesh::ParameterMultiAccessor< T >, libMesh::ParsedFEMFunctionParameter< T >, libMesh::ParameterPointer< T >, libMesh::ParsedFunctionParameter< T >, and libMesh::ParameterMultiPointer< T >.
