Detailed Description

template<class... Args>
class ns3::TupleValue< Args >

Hold objects of type std::tuple<Args...>.

Template Parameters

Args	[explicit] The list of AttributeValues to be held by this TupleValue

Definition at line 68 of file tuple.h.

Member Typedef Documentation

◆ result_type

template<class... Args>

typedef std::tuple<std::invoke_result_t<decltype(&Args::Get), Args>...> ns3::TupleValue< Args >::result_type

Type returned by Get or passed in Set.

Definition at line 74 of file tuple.h.

◆ value_type

template<class... Args>

typedef std::tuple<Args...> ns3::TupleValue< Args >::value_type

Type of value stored in the TupleValue.

Definition at line 72 of file tuple.h.

◆ TupleValue() [1/2]

template<class... Args>

ns3::TupleValue< Args >::TupleValue

Definition at line 215 of file tuple.h.

◆ TupleValue() [2/2]

template<class... Args>

ns3::TupleValue< Args >::TupleValue ( const result_type & value )

Construct this TupleValue from a std::tuple.

Parameters

[in] value Value with which to construct.

Definition at line 221 of file tuple.h.

References ns3::Config::Set().

Here is the call graph for this function:

Member Function Documentation

◆ Copy()

template<class... Args>

Ptr< AttributeValue > ns3::TupleValue< Args >::Copy ( ) const

overridevirtual

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

Implements ns3::AttributeValue.

Definition at line 228 of file tuple.h.

References ns3::Create().

Here is the call graph for this function:

◆ DeserializeFromString()

template<class... Args>

bool ns3::TupleValue< Args >::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 252 of file tuple.h.

◆ Get()

template<class... Args>

TupleValue< Args... >::result_type ns3::TupleValue< Args >::Get

Get the stored values as a std::tuple.

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

Returns: stored values as a std::tuple

Definition at line 311 of file tuple.h.

Here is the caller graph for this function:

◆ GetAccessor()

template<class... Args>

template<typename T >

bool ns3::TupleValue< Args >::GetAccessor ( T & value ) const

Set the given variable to the values stored by this TupleValue object.

Template Parameters

T	[deduced] the type of the given variable (normally, the argument type of a set method or the type of a data member)

Returns: true if the given variable was set

Definition at line 333 of file tuple.h.

◆ GetValue()

template<class... Args>

TupleValue< Args... >::value_type ns3::TupleValue< Args >::GetValue

Get the attribute values as a tuple.

Returns: the attribute values as a tuple

Definition at line 325 of file tuple.h.

◆ SerializeToString()

template<class... Args>

std::string ns3::TupleValue< Args >::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 302 of file tuple.h.

◆ Set()

template<class... Args>

void ns3::TupleValue< Args >::Set ( const result_type & value )

Set the stored values.

Definition at line 318 of file tuple.h.

Here is the caller graph for this function:

◆ SetValueImpl()

template<class... Args>

template<std::size_t... Is>

bool ns3::TupleValue< Args >::SetValueImpl	(	std::index_sequence< Is... >	,
		const std::vector< Ptr< AttributeValue >> &	values
	)

private

Set the attribute values starting from the given values.

Used by DeserializeFromString method.

Template Parameters

Is	[deduced] index sequence

Parameters

values the given attribute values

Returns: true if the attribute values of this object were set

Definition at line 236 of file tuple.h.
