C++ (Cpp) CacheBin::getRecordStatus示例

示例#1

文件： TerrainLayer.cpp 项目： czz2012/osgearth

bool
TerrainLayer::isCached(const TileKey& key) const
{
    CacheBin* bin = const_cast<TerrainLayer*>(this)->getCacheBin( key.getProfile() );
    if ( !bin )
        return false;

    TimeStamp minTime = this->getCachePolicy().getMinAcceptTime();

    return bin->getRecordStatus( key.str(), minTime ) == CacheBin::STATUS_OK;
}

bool

        return false;
    else if ( getCachePolicy() == CachePolicy::CACHE_ONLY )
        return true;

    // next check for a bin:

    if ( !bin )
        return false;
    
    return bin->getRecordStatus( key.str() ) == CacheBin::STATUS_OK;
