Detailed Description

template<typename T>
class ns3::EnumValue< T >

Hold variables of type enum.

This class can be used to hold variables of any kind of enum.

This is often used with ObjectFactory and Config to bind the value of a particular enum to an Attribute or Config name. For example,

Ptr<RateErrorModel> model = CreateObjectWithAttributes<RateErrorModel> (
  "ErrorRate", DoubleValue (0.05),
  "ErrorUnit", EnumValue (RateErrorModel::ERROR_UNIT_PACKET));
 
Config::SetDefault ("ns3::RipNg::SplitHorizon",
                    EnumValue (RipNg::NO_SPLIT_HORIZON));

Member Function Documentation

Copy()

template<typename T >

Ptr< AttributeValue > ns3::EnumValue< T >::Copy ( ) const

overridevirtual

Returns

a deep copy of this class, wrapped into an Attribute object.

Implements ns3::AttributeValue.

Definition at line 102 of file enum.h.

References ns3::Create().

Here is the call graph for this function:

DeserializeFromString()

template<typename T >

bool ns3::EnumValue< T >::DeserializeFromString ( std::string value, Ptr< const AttributeChecker > checker )

overridevirtual

Parameters

[in]	value	A string representation of the value
[in]	checker	A pointer to the checker associated to the attribute.

Returns

true if the input string was correctly-formatted and could be successfully deserialized, false otherwise.

Upon return of this function, this AttributeValue instance contains the deserialized value. In most cases, this method will not make any use of the checker argument. However, in a very limited set of cases, the checker argument is needed to perform proper serialization. A nice example of code which needs it is the EnumValue::SerializeToString code.

Implements ns3::AttributeValue.

SerializeToString()

template<typename T >

std::string ns3::EnumValue< T >::SerializeToString ( Ptr< const AttributeChecker > checker ) const

Parameters

[in]

checker

The checker associated to the attribute

Returns

A string representation of this value.

In most cases, this method will not make any use of the checker argument. However, in a very limited set of cases, the checker argument is needed to perform proper serialization. A nice example of code which needs it is the EnumValue::SerializeToString code.
