Detailed Description

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

Hold variables of type enum.

AttributeValue implementation for 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,

"ErrorRate", DoubleValue (0.05),
Config::SetDefault ("ns3::RipNg::SplitHorizon",
This class can be used to hold variables of floating point type such as 'double' or 'float'.
Definition double.h:31

Definition enum.h:52
Smart pointer class similar to boost::intrusive_ptr.
@ NO_SPLIT_HORIZON
No Split Horizon.

Ptr< T > CreateObjectWithAttributes(Args... args)
Allocate an Object on the heap and initialize with a set of attributes.

Constructor & Destructor Documentation

◆ EnumValue() [1/2]

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

◆ EnumValue() [2/2]

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

Constructor.

Parameters
[in]valueThe Enum value to use.

Definition at line 73 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 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]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 245 of file enum.h.

References NS_ASSERT, and ns3::PeekPointer().

+ Here is the call graph for this function:

◆ Get()

template<typename T >
T ns3::EnumValue< T >::Get ( ) const
Returns
The Enum value.

Definition at line 87 of file enum.h.

Referenced by ns3::EnumChecker< T >::Check(), and ns3::LteHelper::InstallSingleEnbDevice().

+ Here is the caller graph for this function:

◆ GetAccessor()

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

Access the Enum value as type T.

Template Parameters
T[explicit] The type to cast to.
Parameters
[out]valueThe Enum value, as type T.
Returns
true.

Definition at line 94 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.

Implements ns3::AttributeValue.

+ Here is the call graph for this function:

◆ Set()

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

Set the value.

Parameters
[in]valueThe value to adopt.

Definition at line 80 of file enum.h.
