Detailed Description

Hold a value for an Attribute.

Instances of this class should always be wrapped into an Attribute object. Most subclasses of this base class are implemented by the ATTRIBUTE_HELPER_* macros.

Member Function Documentation

Copy()

virtual Ptr< AttributeValue > ns3::AttributeValue::Copy ( void  ) const

pure virtual

Returns

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

Implemented in ns3::AttributeContainerValue< A, C >, ns3::EmptyAttributeValue, ns3::BooleanValue, ns3::CallbackValue, ns3::DoubleValue, ns3::EnumValue, ns3::IntegerValue, ns3::LengthValue, ns3::TimeValue, ns3::ObjectFactoryValue, ns3::ObjectPtrContainerValue, ns3::PairValue< A, B >, ns3::PointerValue, ns3::StringValue, ns3::TypeIdValue, ns3::UintegerValue, ns3::Vector3DValue, ns3::Vector2DValue, and ns3::TupleValue< Args >.

Referenced by ns3::TypeId::AddAttribute(), ns3::AttributeChecker::CreateValidValue(), and ns3::ObjectFactory::DoSet().

Here is the caller graph for this function:

DeserializeFromString()

virtual bool ns3::AttributeValue::DeserializeFromString ( std::string  value, Ptr< const AttributeChecker >  checker  )

pure virtual

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.

Implemented in ns3::AttributeContainerValue< A, C >, ns3::EmptyAttributeValue, ns3::BooleanValue, ns3::CallbackValue, ns3::DoubleValue, ns3::EnumValue, ns3::IntegerValue, ns3::LengthValue, ns3::TimeValue, ns3::ObjectFactoryValue, ns3::ObjectPtrContainerValue, ns3::PairValue< A, B >, ns3::PointerValue, ns3::StringValue, ns3::TypeIdValue, ns3::UintegerValue, ns3::Vector3DValue, ns3::Vector2DValue, and ns3::TupleValue< Args >.

SerializeToString()

virtual std::string ns3::AttributeValue::SerializeToString ( Ptr< const AttributeChecker >  checker ) const

pure virtual

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.

Implemented in ns3::AttributeContainerValue< A, C >, ns3::EmptyAttributeValue, ns3::BooleanValue, ns3::CallbackValue, ns3::DoubleValue, ns3::EnumValue, ns3::IntegerValue, ns3::LengthValue, ns3::TimeValue, ns3::ObjectFactoryValue, ns3::ObjectPtrContainerValue, ns3::PairValue< A, B >, ns3::PointerValue, ns3::StringValue, ns3::TypeIdValue, ns3::UintegerValue, ns3::Vector3DValue, ns3::Vector2DValue, and ns3::TupleValue< Args >.
