[Gems-users] How to access cache entry in LRUPolicy

[Liz Joy <lizjoy86@xxxxxxxxx>]

Hii
I want to access each cache entry m_cache[set][i] in getVictimOwner(Index set,NodeID processorid) of LRUPolicy.h file.
I need to check the condition.
for(unsigned int i=0;i < m_assoc; i++)
{
        if(m_cache[set][i].m_Address.m_processorid == processorid)............................//line no 98
        {
                smallest_time = m_last_ref_ptr[set][i];
                smallest_index = i;
                break;

        }
}

for (unsigned int i=0; i < m_assoc; i++)
 {

        if(m_cache[set][i].m_Address.m_processorid == processorid)....................//line no 109
        {
                 time = m_last_ref_ptr[set][i];
                                 //assert(m_cache[cacheSet][i].m_Permission != AccessPermission_NotPresent);

                if (time < smallest_time)
                {
                         smallest_index = i;
                         smallest_time = time;
                }
         }
  }
But the checking condition is giving an error saying

Can anyone please help to remove this error.How can I access m_cache[set][j].m_Address.m_processorid???
Expecting a reply soon
Thanks in advance
