SparseImmutableTable

                     ImmutableSet<C> columnSpace)

Method Detail

columnMap

public ImmutableMap<C,java.util.Map<R,V>> columnMap()

Description copied from class: ImmutableTable

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().

The value Map<R, V> instances in the returned map are ImmutableMap instances as well.

Specified by:

columnMap in interface Table<R,C,V>

Specified by:

columnMap in class ImmutableTable<R,C,V>

Returns:

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

rowMap

public ImmutableMap<R,java.util.Map<C,V>> rowMap()

Description copied from class: ImmutableTable

Returns a view that associates each row key with the corresponding map from column 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 rowMap().get() have the same behavior as those returned by Table.row(R). Those maps may support setValue(), put(), and putAll().

The value Map<C, V> instances in the returned map are ImmutableMap instances as well.

Specified by:

rowMap in interface Table<R,C,V>

Specified by:

rowMap in class ImmutableTable<R,C,V>

Returns:

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

size

public int size()

Description copied from interface: Table

Returns the number of row key / column key / value mappings in the table.

getCell

Table.Cell<R,C,V> getCell(int index)

Specified by:

getCell in class RegularImmutableTable<R,C,V>

getValue

V getValue(int index)

Specified by:

getValue in class RegularImmutableTable<R,C,V>

createSerializedForm

ImmutableTable.SerializedForm createSerializedForm()

Description copied from class: ImmutableTable

Creates the common serialized form for this table.

Specified by:

createSerializedForm in class ImmutableTable<R,C,V>
