Detailed Description

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

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

This ParameterAccessor subclass is specific to ParsedFunction objects: it stores a pointer to the ParsedFunction and a string describing the parameter (an inline variable) name to be accessed.

Author

Roy Stogner

Date

2015 Stores a pointer to a parsed function and a string for the parameter.

Constructor & Destructor Documentation

ParsedFunctionParameter()

template<typename T = Number>

libMesh::ParsedFunctionParameter< T >::ParsedFunctionParameter ( ParsedFunction< T > &  func_ref, std::string  param_name  )

inline

Constructor: take the function to be modified and the name of the inline variable within it which represents our parameter.

The restrictions of get_inline_value() and set_inline_value() in ParsedFunction apply to this interface as well.

Note

Only the function referred to here is changed by set() - any clones of the function which precede the set() remain at their previous values.

Definition at line 62 of file parsed_function_parameter.h.

A new copy of the accessor.

operator*() [1/2]

template<typename T = Number>

ParameterProxy<T> libMesh::ParameterAccessor< T >::operator* ( )

inlineinherited

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.

A simple reseater won't work with a parsed function.
