Detailed Description

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

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

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.

Constructor & Destructor Documentation

template<typename T = Number>
libMesh::ParsedFunctionParameter< T >::ParsedFunctionParameter ( ParsedFunction< T > &  func_ref,
const std::string &  param_name 

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

Returns a new copy of the accessor.

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

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.
