Detailed Description

Hold variables of type enum.

AttributeValue implementation for Enum.

This class can be used to hold variables of any kind of enum.

This is often used with ObjectFactory and Config to bind the value of a particular enum to an Attribute or Config name. For example,

Ptr<RateErrorModel> model = CreateObjectWithAttributes<RateErrorModel> (
  "ErrorRate", DoubleValue (0.05),
  "ErrorUnit", EnumValue (RateErrorModel::ERROR_UNIT_PACKET));
Config::SetDefault ("ns3::RipNg::SplitHorizon",
                    EnumValue (RipNg::NO_SPLIT_HORIZON));

ns3::EnumValue::EnumValue ( int value )

Construct from an explicit value.

Parameters

Member Function Documentation

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

virtual

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

Implements ns3::AttributeValue.

Definition at line 58 of file enum.cc.

References NS_LOG_FUNCTION.

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

virtual

Parameters

value	a string representation of the value
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.

int ns3::EnumValue::Get ( void ) const

Returns: The Enum value.

Referenced by ns3::EnumChecker::Check(), and ns3::LteHelper::InstallSingleEnbDevice().

Here is the caller graph for this function:

template<typename T >

bool ns3::EnumValue::GetAccessor ( T & value ) const

Access the Enum value as type T.

Parameters

[out] value The Enum value, as type T.

Returns: true.

Definition at line 79 of file enum.h.

References m_value.

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

virtual

Parameters

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.
