Constructor Detail

PartitionManagerFromIndexDirectory

public PartitionManagerFromIndexDirectory(String name,
                                  FeatureCollectionConfig config,
                                  File directory,
                                  org.slf4j.Logger logger)

Method Detail

makePartitions

public Iterable<MCollection> makePartitions(CollectionUpdateType forceCollection)
                                     throws IOException

Specified by:

makePartitions in interface PartitionManager

Throws:

IOException

close

public void close()

Description copied from interface: MCollection

Close and release any resources. Do not make further calls on this object.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface MCollection

isLeaf

public boolean isLeaf()

Description copied from interface: MCollection

Consider MCollections as a tree. At the leaves are a single mfile or mfile collection. A leaf MCollection will be a GC if it has a single runtime, or a PofGC otherwise. A non-leaf is a directory with other directories under it. It will either be a PofGC (Partition of GC) or PofP (Partition of Partition).

Specified by:

isLeaf in interface MCollection

Overrides:

isLeaf in class CollectionAbstract

Returns:

if leaf collection

getFilesSorted

public Iterable<MFile> getFilesSorted()
                               throws IOException

Description copied from interface: MCollection

Get the current collection of MFile. if hasDateExtractor() == true, these will be sorted by Date, otherwise by path.

Specified by:

getFilesSorted in interface MCollection

Returns:

current collection of MFile as an Iterable.

Throws:

IOException

getFileIterator

public CloseableIterator<MFile> getFileIterator()
                                         throws IOException

Description copied from interface: MCollection

Get the current collection of MFile, no guaranteed order. May be faster for large collections, use when order is not important.

     try (CloseableIterator iter = getFileIterator()) {
      while (iter.hasNext()) {
        MFile file = iter.next();
      }
    }
 

Specified by:

getFileIterator in interface MCollection

Returns:

current collection of MFile as an CloseableIterator.

Throws:

IOException
