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),
Config::SetDefault ("ns3::RipNg::SplitHorizon",
@ NO_SPLIT_HORIZON
No Split Horizon.

void SetDefault(std::string name, const AttributeValue &value)

Constructor & Destructor Documentation

◆ EnumValue() [1/2]

template<typename T >
ns3::EnumValue< T >::EnumValue ( )
default

◆ EnumValue() [2/2]

template<typename T >
ns3::EnumValue< T >::EnumValue ( value)

Construct from an explicit value.

Parameters
[in]valueThe value to begin with.

Definition at line 88 of file enum.h.

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 117 of file enum.h.

◆ DeserializeFromString()

template<typename T >
bool ns3::EnumValue< T >::DeserializeFromString ( std::string  value,
Ptr< const AttributeChecker checker 
)
overridevirtual
Parameters
[in]valueA string representation of the value
[in]checkerA 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.

Definition at line 260 of file enum.h.

◆ Get()

◆ GetAccessor()

template<typename T >
bool ns3::EnumValue< T >::GetAccessor ( T &  value) const

Definition at line 109 of file enum.h.

◆ SerializeToString()

template<typename T >
std::string ns3::EnumValue< T >::SerializeToString ( Ptr< const AttributeChecker checker) const
overridevirtual
Parameters
[in]checkerThe 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.
