Constructor Detail

PartitionManagerFromIndexList

public PartitionManagerFromIndexList(MCollection dcm,
                                     java.util.List<MFile> partFiles,
                                     org.slf4j.Logger logger)

Method Detail

makePartitions

public java.lang.Iterable<MCollection> makePartitions(CollectionUpdateType forceCollection)
                                               throws java.io.IOException

Specified by:

makePartitions in interface PartitionManager

Throws:

java.io.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 java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface MCollection

getFilesSorted

public java.lang.Iterable<MFile> getFilesSorted()
                                         throws java.io.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:

java.io.IOException

getFileIterator

public CloseableIterator<MFile> getFileIterator()
                                         throws java.io.IOException

Description copied from interface: MCollection

Get the current collection of MFile, no guaranteed order. May be faster than getFilesSorted() 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:

java.io.IOException

removePartition

public void removePartition(MCollection partition)

Specified by:

removePartition in interface PartitionManager
