Implements com.google.common.collect.Table.cellSet.

Doc from com.google.common.collect.Table.cellSet.

Returns a set of all row key / column key / value triplets. Changes to the returned set will update the underlying table, and vice versa. The cell set does not support the add or addAll methods.

public Map<R, V> column(C columnKey)

Implements com.google.common.collect.Table.column.

Doc from com.google.common.collect.Table.column.

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:C

Returns:Map<R, V>

Doc from com.google.common.collect.Table.columnMap.

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 column. Those maps may support setValue(), put(), and putAll().
