        public static <T extends @Nullable Object,​R,​C,​V> Collector<T,​?,​ImmutableTable<R,​C,​V>> toImmutableTable​(Function<? super T,​? extends R> rowFunction,
                                                                                                                                                         Function<? super T,​? extends C> columnFunction,

        Returns a Collector that accumulates elements into an ImmutableTable. Each input element is mapped to one cell in the returned table, with the rows, columns, and values generated by applying the specified functions.

        The returned Collector will throw a NullPointerException at collection time if the row, column, or value functions return null on any input.

        Returns a Collector that accumulates elements into an ImmutableTable. Each input element is mapped to one cell in the returned table, with the rows, columns, and values generated by applying the specified functions. If multiple inputs are mapped to the same row and column pair, they will be combined with the specified merging function in encounter order.

        The returned Collector will throw a NullPointerException at collection time if the row, column, value, or merging functions return null on any input.

        public static <R,​C,​V> ImmutableTable<R,​C,​V> of()
        Returns an empty immutable table.

        Performance note: the instance returned is a singleton.

      • cellSet

        public ImmutableSet<Table.Cell<R,​C,​V>> cellSet()
        Description copied from interface: Table
        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.
        Specified by:
        cellSet in interface Table<R,​C,​V>
        Returns:
        set of table cells consisting of row key / column key / value triplets
      • values

        public ImmutableCollection<Vvalues()
        Description copied from interface: Table
        Returns a collection of all values, which may contain duplicates. Changes to the returned collection will update the underlying table, and vice versa.
        Specified by:
        values in interface Table<R,​C,​V>
        Returns:
        collection of values
      • column

        public ImmutableMap<R,​Vcolumn​(C columnKey)
        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.

        Specified by:
        column in interface Table<R,​C,​V>
        Parameters:
        columnKey - key of column to search for in the table
        Returns:
        the corresponding map from row keys to values
        Throws:
        NullPointerException - if columnKey is null
      • columnKeySet

        public ImmutableSet<CcolumnKeySet()
        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<R,​C,​V>
        Returns:
        set of column keys
      • columnMap

        public abstract ImmutableMap<C,​Map<R,​V>> 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 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>
        Returns:
        a map view from each column key to a secondary map from row keys to values
      • row

        public ImmutableMap<C,​Vrow​(R rowKey)
        Returns a view of all mappings that have the given row key. For each row key / column key / value mapping in the table with that row key, the returned map associates the column key with the value. If no mappings in the table have the provided row key, an empty map is returned.

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

        Returns:
        set of row keys
      • rowMap
