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

virtual bool ns3::AttributeValue::DeserializeFromString ( std::string  value,
Ptr< const AttributeChecker checker 
pure virtual
[in]valueA string representation of the value
[in]checkerA pointer to the checker associated to the attribute.
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.
