Detailed Description

allow setting and getting the value of an attribute.

The goal of this class is to hide from the user how an attribute is actually set or get to or from a class instance. Implementations of this base class are usually provided through the MakeAccessorHelper template functions, hidden behind an ATTRIBUTE_HELPER_* macro.

Member Function Documentation

virtual bool ns3::AttributeAccessor::Get ( const ObjectBase *  object, AttributeValue &  attribute  ) const

pure virtual

Parameters

object	the object instance to get the value from
attribute	a pointer to where the value should be set.

Returns

true if the value could be read successfully, and stored in the input value, false otherwise.

This method expects that the caller has checked that the input value is valid with AttributeChecker::Check.

Implemented in ns3::ObjectPtrContainerAccessor, ns3::AccessorHelper< T, U >, and ns3::NscStackStringAccessor.

Referenced by ns3::ObjectBase::GetAttribute(), and ns3::ObjectBase::GetAttributeFailSafe().

Here is the caller graph for this function:

virtual bool ns3::AttributeAccessor::HasGetter ( void  ) const

pure virtual

Returns

true if this accessor supports the Get operation, false otherwise.

Implemented in ns3::ObjectPtrContainerAccessor, and ns3::NscStackStringAccessor.

Referenced by ns3::AttributeIterator::DoIterate(), ns3::ObjectBase::GetAttribute(), ns3::ObjectBase::GetAttributeFailSafe(), and PrintAttributes().

Here is the caller graph for this function:

virtual bool ns3::AttributeAccessor::HasSetter ( void  ) const

pure virtual

Returns

true if this accessor supports the Set operation, false otherwise.

Implemented in ns3::ObjectPtrContainerAccessor, and ns3::NscStackStringAccessor.

Referenced by ns3::AttributeIterator::DoIterate(), ns3::AttributeDefaultIterator::Iterate(), PrintAttributes(), ns3::ObjectBase::SetAttribute(), and ns3::ObjectBase::SetAttributeFailSafe().

Here is the caller graph for this function:

virtual bool ns3::AttributeAccessor::Set ( ObjectBase *  object, const AttributeValue &  value  ) const

pure virtual

Parameters

object	the object instance to set the value in
value	the value to set

Returns

true if the value could be set successfully, false otherwise.

This method expects that the caller has checked that the input value is valid with AttributeChecker::Check.

Implemented in ns3::ObjectPtrContainerAccessor, ns3::AccessorHelper< T, U >, and ns3::NscStackStringAccessor.
