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] value Value with which to construct.

Here is the call graph for this function:

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 311 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]	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.

Definition at line 325 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 378 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] value The Pair value, as type T.

Returns: true.

Definition at line 393 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] 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.

Implements ns3::AttributeValue.

Definition at line 366 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] value The value to adopt.
