Constructor & Destructor Documentation

◆ PointerValue() [1/3]

ns3::PointerValue::PointerValue ( )

Definition at line 37 of file pointer.cc.

References NS_LOG_FUNCTION.

◆ PointerValue() [2/3]

ns3::PointerValue::PointerValue ( const Ptr< Object > &  object)

Construct this PointerValue by referencing an explicit Object.

Parameters
[in]objectThe object to begin with.

Definition at line 43 of file pointer.cc.

References NS_LOG_FUNCTION.

◆ PointerValue() [3/3]

template<typename T >
ns3::PointerValue::PointerValue ( const Ptr< T > &  object)

Construct this PointerValue by referencing an explicit Object.

Template Parameters
T[deduced] The type of the object.
Parameters
[in]objectThe object to begin with.

Definition at line 220 of file pointer.h.

References m_value.

Member Function Documentation

◆ Copy()

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

Implements ns3::AttributeValue.

Definition at line 64 of file pointer.cc.

References NS_LOG_FUNCTION.

◆ DeserializeFromString()

bool ns3::PointerValue::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.

◆ Get()

template<typename T >
Ptr< T > ns3::PointerValue::Get
Returns
The Pointer value.
Template Parameters
T[explicit] The type to cast to.
