◆ AllEqual()

bool ns3::dsr::DsrPassiveBuffer::AllEqual ( DsrPassiveBuffEntry & entry )

Note: For real this function checks if at most one entry is equal. If it is, that entry is removed. Further entries are NOT checked. This could be a bug.

Parameters

entry The Entry to check

Returns: true if an Entry was found and removed.
