Detailed Description

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

Base class for reading/writing sensitivity 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.

Constructor & Destructor Documentation

◆ ~ParameterAccessor()

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

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.

Definition at line 91 of file parameter_accessor.h.

91 { return ParameterProxy<T>(*this); }

◆ operator*() [2/2]

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

Definition at line 93 of file parameter_accessor.h.

93 { return ConstParameterProxy<T>(*this); }

◆ operator=()

template<typename T = Number>
virtual ParameterAccessor<T>& libMesh::ParameterAccessor< T >::operator= ( T *  )
inlinevirtual

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

Definition at line 82 of file parameter_accessor.h.

82 { libmesh_error(); return *this; }

◆ set()

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