def default_value_for_type(type)
  case type
    when :integer then 1
    else "generic"
  end
end

#lookup_variable_value(name, all_variables, known_variable_types) ⇒ Object

Finds the variable in the all_variables hash whose name matches the specified name (string or symbol), and then returns its value. If that value is an instance of Rtml::ReverseEngineering::Simulator::VariableValue, calls the #value method on that object instead.

If the variable is not found, then a default value will be returned depending on its type.

def lookup_variable_value(name, all_variables, known_variable_types)
  all_variables.each do |var_name, varval|
    if var_name.to_s == name
      return(varval.kind_of?(Rtml::ReverseEngineering::Simulator::VariableValue) ? varval.value : varval)
    end
  end
  default_value_for_type(known_variable_types[name])
end

#resolve(value, all_variables, known_variable_types) ⇒ Object

Checks a value to see if it references a TML variable; if so, it resolves that variable into its value; otherwise, the original value is returned.
