◆ CanBeInserted()

bool ns3::WifiDefaultAssocManager::CanBeInserted ( const StaWifiMac::ApInfo & apInfo) const
overrideprotectedvirtual

Allow subclasses to choose whether the given ApInfo shall be considered and hence inserted in the sorted list of ApInfo objects.

◆ CanBeReturned()

bool ns3::WifiDefaultAssocManager::CanBeReturned ( const StaWifiMac::ApInfo & apInfo) const
overrideprotectedvirtual

Allow subclasses to choose whether the given ApInfo shall be returned or discarded when the STA wifi MAC requests information on the best AP.

Parameters
apInfothe apInfo object to return
Returns
true if the apInfo object can be returned, false otherwise

Implements ns3::WifiAssocManager.

Definition at line 294 of file wifi-default-assoc-manager.cc.

◆ ChannelSwitchTimeout()

void ns3::WifiDefaultAssocManager::ChannelSwitchTimeout ( uint8_t linkId)

◆ Compare()

bool ns3::WifiDefaultAssocManager::Compare ( const StaWifiMac::ApInfo & lhs,
const StaWifiMac::ApInfo & rhs ) const
overridevirtual

Compare two ApInfo objects for the purpose of keeping a sorted list of ApInfo objects.

Parameters
lhsleft hand side ApInfo object
rhsright hand side ApInfo object
Returns
true if the left hand side ApInfo object should be placed before the right hand side ApInfo object in the sorted list of ApInfo objects, false otherwise

Implements ns3::WifiAssocManager.

Definition at line 67 of file wifi-default-assoc-manager.cc.

References ns3::StaWifiMac::ApInfo::m_snr.

◆ DoDispose()

void ns3::WifiDefaultAssocManager::DoDispose ( )
overrideprotectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::WifiAssocManager.
