PageList { boolean tryEvict( long pageRef, EvictionEventOpportunity evictionOpportunity ) throws IOException { if ( tryExclusiveLock( pageRef ) ) { if ( isLoaded( pageRef ) ) { try ( EvictionEvent evictionEvent = evictionOpportunity.beginEviction() ) { evict( pageRef, evictionEvent ); return true; } } unlockExclusive( pageRef ); } return false; } PageList( int pageCount, int cachePageSize, MemoryAllocator memoryAllocator, SwapperSet swappers,
              long victimPageAddress, long bufferAlignment );   PageList( PageList pageList );   }### Answer:
