      • clear

        public void clear()
        Description copied from interface: Table
        Removes all mappings from the table.
        Specified by:
        clear in interface Table<C,​R,​V>
        Overrides:
        clear in class AbstractTable<C,​R,​V>

      • column

        public java.util.Map<C,​V> column​(R columnKey)
        Description copied from interface: Table
        Returns a view of all mappings that have the given column key. For each row key / column key / value mapping in the table with that column key, the returned map associates the row key with the value. If no mappings in the table have the provided column key, an empty map is returned.

        Changes to the returned map will update the underlying table, and vice versa.

        Parameters:
        columnKey - key of column to search for in the table
        Returns:
        the corresponding map from row keys to values

      • columnKeySet

        public java.util.Set<R> columnKeySet()
        Description copied from interface: Table
        Returns a set of column keys that have one or more values in the table. Changes to the set will update the underlying table, and vice versa.
        Specified by:
        columnKeySet in interface Table<C,​R,​V>
        Overrides:
        columnKeySet in class AbstractTable<C,​R,​V>
        Returns:
        set of column keys

      • columnMap

        public java.util.Map<R,​java.util.Map<C,​V>> columnMap()
        Description copied from interface: Table
        Returns a view that associates each column key with the corresponding map from row keys to values. Changes to the returned map will update this table. The returned map does not support put() or putAll(), or setValue() on its entries.

        In contrast, the maps returned by columnMap().get() have the same behavior as those returned by Table.column(C). Those maps may support setValue(), put(), and putAll().

        Returns:
        a map view from each column key to a secondary map from row keys to values

        Changes to the returned map will update the underlying table, and vice versa.

        Parameters:
        rowKey - key of row to search for in the table
