Detailed Description

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

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.

Author
Roy Stogner
Date
2015 Base class for reading/writing sensitivity parameters.

Constructor & Destructor Documentation

◆ ~ParameterAccessor()

template<typename T = Number>
virtual libMesh::ParameterAccessor< T >::~ParameterAccessor ( )
virtualdefault

Virtual destructor - we'll be deleting subclasses from pointers-to-ParameterAccessor.

Member Function Documentation

◆ clone()

template<typename T = Number>
virtual std::unique_ptr<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 >.

Referenced by libMesh::ParameterMultiAccessor< T >::push_back().

◆ get()

template<typename T = Number>
virtual const T& libMesh::ParameterAccessor< T >::get ( ) const
pure virtual

◆ operator*() [1/2]

template<typename T = Number>
ParameterProxy<T> libMesh::ParameterAccessor< T >::operator* ( )
inline

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.

template<typename T = Number>
ConstParameterProxy<T> libMesh::ParameterAccessor< T >::operator* ( ) const

◆ set()

template<typename T = Number>
virtual void libMesh::ParameterAccessor< T >::set ( const T &  new_value)
