Constructor & Destructor Documentation

◆ PairValue() [1/2]

template<class A , class B >
ns3::PairValue< A, B >::PairValue ( )
inline

Definition at line 65 of file pair.h.

◆ PairValue() [2/2]

template<class A , class B >
ns3::PairValue< A, B >::PairValue ( const result_type & value)
inline

Construct this PairValue from a std::pair.

Parameters
[in]valueValue with which to construct.

Member Function Documentation

◆ Copy()

template<class A , class B >
Ptr< AttributeValue > ns3::PairValue< A, B >::Copy ( ) const
overridevirtual
Returns
a deep copy of this class, wrapped into an Attribute object.

Implements ns3::AttributeValue.

Definition at line 313 of file pair.h.

References ns3::Create(), and ns3::DynamicCast().

+ Here is the call graph for this function:

◆ DeserializeFromString()

template<class A , class B >
bool ns3::PairValue< A, B >::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 327 of file pair.h.

References ns3::DynamicCast().

+ Here is the call graph for this function:

◆ Get()

template<class A , class B >
PairValue< A, B >::result_type ns3::PairValue< A, B >::Get ( ) const

Get the stored value as a std::pair.

This differs from the actual value stored in the object which is a pair of Ptr<AV> where AV is a class derived from AttributeValue.

Returns
stored value as std::pair<A, B>.

Definition at line 380 of file pair.h.

+ Here is the caller graph for this function:

◆ GetAccessor()

template<class A , class B >
template<typename T >
bool ns3::PairValue< A, B >::GetAccessor ( T & value) const

Access the Pair value as type T.

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

Definition at line 395 of file pair.h.

◆ SerializeToString()

template<class A , class B >
std::string ns3::PairValue< A, B >::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.

Definition at line 368 of file pair.h.

◆ Set()

template<class A , class B >
void ns3::PairValue< A, B >::Set ( const result_type & value)

Set the value.

Parameters
[in]valueThe value to adopt.
