Member Function Documentation

verifyFunction()

const std::string MooseParsedFunctionBase::verifyFunction ( const std::string &  function_str )

protected

A helper method to check if the function value contains quotes.

This method should be called from within the initialization list of the object inheriting the MooseParsedFunctionInterface

Parameters

function_str

The name of the ParsedFunction

Returns

The vector of strings, if the input function is valid

ParsedFunction

Definition at line 47 of file MooseParsedFunctionBase.C.

{
  // Throws an error if quotes are found
  if (function_str.find("\"") != std::string::npos)
    mooseError("The value in ParsedFunction contains quotes(\") which cannot be properly parsed");

  // Return the input equation (no error)
  return function_str;
}
