Detailed Description

Represent the type of an attribute.

Each type of attribute has an associated unique AttributeChecker subclass. The type of the subclass can be safely used by users to infer the type of the associated attribute. i.e., we expect binding authors to use the checker associated to an attribute to detect the type of the associated attribute.

Most subclasses of this base class are implemented by the ATTRIBUTE_HELPER_HEADER and ATTRIBUTE_HELPER_CPP macros.

Member Function Documentation

virtual bool ns3::AttributeChecker::Check ( const AttributeValue &  value ) const

pure virtual

Parameters

value

a pointer to the value to check

Returns

true if the input value is both of the right type and if its value is within the requested range. Returns false otherwise.

Implemented in ns3::internal::AnObjectPtrContainerChecker< T >, and ns3::EnumChecker.

Referenced by CreateValidValue().

Here is the caller graph for this function:

virtual bool ns3::AttributeChecker::Copy ( const AttributeValue &  source, AttributeValue &  destination  ) const

pure virtual

Implemented in ns3::internal::AnObjectPtrContainerChecker< T >, and ns3::EnumChecker.

Referenced by ns3::GlobalValue::GetValue().

Here is the caller graph for this function:

virtual Ptr<AttributeValue> ns3::AttributeChecker::Create ( void  ) const

pure virtual

Returns

a new instance of an AttributeValue (wrapper in an Attribute instance) which matches the type of the underlying attribute.

This method is typically used to create a temporary variable prior to calling Attribute::DeserializeFromString.

Implemented in ns3::internal::AnObjectPtrContainerChecker< T >, and ns3::EnumChecker.

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

Here is the caller graph for this function:

Ptr< AttributeValue > ns3::AttributeChecker::CreateValidValue

(

const AttributeValue &

value

)

Here is the caller graph for this function:

virtual std::string ns3::AttributeChecker::GetUnderlyingTypeInformation ( void  ) const

pure virtual

Returns

a human-readable representation of information about the underlying C++ type.

Implemented in ns3::internal::AnObjectPtrContainerChecker< T >, and ns3::EnumChecker.

Referenced by ns3::cell_tooltip_callback(), ns3::cell_tooltip_callback_config_default(), and PrintAttributes().

Here is the caller graph for this function:

virtual std::string ns3::AttributeChecker::GetValueTypeName ( void  ) const

pure virtual

Returns

the c++ fully-qualified typename of the subclass of the ns3::AttributeValue base class which is associated to this checker.

A typical return value here is FooValue where Foo is the name of the type being wrapped.

Implemented in ns3::internal::AnObjectPtrContainerChecker< T >, and ns3::EnumChecker.

Referenced by ns3::cell_tooltip_callback(), ns3::cell_tooltip_callback_config_default(), and PrintAttributes().

Here is the caller graph for this function:

virtual bool ns3::AttributeChecker::HasUnderlyingTypeInformation ( void  ) const

pure virtual

Returns

true if this checker has information about the underlying C++ type, false otherwise.

If this method returns false, the return value of the GetUnderlyingTypeInformation method cannot be relied upon.

Implemented in ns3::internal::AnObjectPtrContainerChecker< T >, and ns3::EnumChecker.

Referenced by ns3::cell_tooltip_callback(), ns3::cell_tooltip_callback_config_default(), and PrintAttributes().
