示例1: getWriteableDirectories

import org.apache.cassandra.db.Directories.DataDirectory; //导入依赖的package包/类
private List<Directories.DataDirectoryCandidate> getWriteableDirectories(DataDirectory[] dataDirectories, long writeSize)
{
    // copied from Directories.getWriteableLocation(long)
    List<Directories.DataDirectoryCandidate> candidates = new ArrayList<>();

    long totalAvailable = 0L;

    for (DataDirectory dataDir : dataDirectories)
        {
            Directories.DataDirectoryCandidate candidate = new Directories.DataDirectoryCandidate(dataDir);
            // exclude directory if its total writeSize does not fit to data directory
            if (candidate.availableSpace < writeSize)
                continue;
            candidates.add(candidate);
            totalAvailable += candidate.availableSpace;
        }

    Directories.sortWriteableCandidates(candidates, totalAvailable);

    return candidates;
