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

◆ Get()

virtual bool ns3::AttributeAccessor::Get ( const ObjectBase object,
AttributeValue attribute 
) const
pure virtual
Parameters
[in,out]objectThe object instance to get the value from
[out]attributeA 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::EmptyAttributeAccessor, ns3::AccessorHelper< T, U >, and ns3::ObjectPtrContainerAccessor.

◆ HasGetter()

virtual bool ns3::AttributeAccessor::HasGetter ( ) const
pure virtual
Returns
true if this accessor supports the Get operation, false otherwise.

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

◆ HasSetter()

virtual bool ns3::AttributeAccessor::HasSetter ( ) const
pure virtual
Returns
true if this accessor supports the Set operation, false otherwise.

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

◆ Set()

virtual bool ns3::AttributeAccessor::Set ( ObjectBase object,
const AttributeValue value 
) const
pure virtual
Parameters
[in,out]objectThe object instance to set the value in
[in]valueThe 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::AccessorHelper< T, U >, ns3::EmptyAttributeAccessor, and ns3::ObjectPtrContainerAccessor.
