Constructor Detail

Bicluster

public Bicluster(int[] rowIDs,
                 int[] colIDs,
                 Database<V> database)

Defines a new bicluster for given parameters.

Parameters:

rowIDs - the ids of the rows included in the bicluster

colIDs - the ids of the columns included in the bicluster

database - the database this bicluster is defined for

Method Detail

sortIDs

public void sortIDs()

Sorts the row and column ids in ascending order.

size

public int size()

The size of the cluster.

The size of a bicluster is the number of included rows.

Returns:

the size of the bicluster, i.e., the number or rows included in the bicluster

rowIterator

public Iterator<V> rowIterator()

Provides an iterator for the row ids.

Note that the iterator is not guaranteed to touch all elements if the sortIDs() is called during the lifetime of the iterator.

Returns:

an iterator for the row ids

getDatabaseObjectGroup

public DatabaseObjectGroup getDatabaseObjectGroup()

Creates a DatabaseObjectGroup for the row IDs included in this Bicluster.

Returns:

a DatabaseObjectGroup for the row IDs included in this Bicluster

getDatabase

public Database<V> getDatabase()

Getter to retrieve the database

Returns:

Database

getColumnIDs

public int[] getColumnIDs()

Provides a copy of the column IDs contributing to the bicluster.

Returns:

a copy of the columnsIDs

writeToText

public void writeToText(TextWriterStream out,
                        String label)

Implementation of TextWriteable interface.

Specified by:

writeToText in interface TextWriteable

Parameters:

out - Output writer

label - Label
