Method Summary

Modifier and Type	Method and Description
pack-priv static boolean	equalsImpl(Table<?, ?, ?> table, Object obj)
public static <R extends @Nullable Object, C extends @Nullable Object, V extends @Nullable Object> Table.Cell<R, C, V>	immutableCell(R the row key to be associated with the returned cell rowKey, C the column key to be associated with the returned cell columnKey, V the value to be associated with the returned cell value) Returns an immutable cell with the specified row key, column key, and value.
public static <R, C, V> Table<R, C, V>	newCustomTable(Map<R, Map<C, V>> place to store the mapping from each row key to its corresponding column key / value map backingMap, Supplier<? extends Map<C, V>> supplier of new, empty maps that will each hold all column key / value mappings for a given row key factory) Creates a table that uses the specified backing map and factory.
public static <R extends @Nullable Object, C extends @Nullable Object, V extends @Nullable Object> Table<R, C, V>	Returns: a synchronized view of the specified table synchronizedTable(Table<R, C, V> the table to be wrapped in a synchronized view table) Returns a synchronized (thread-safe) table backed by the specified table.
public static <T extends @Nullable Object, R extends @Nullable Object, C extends @Nullable Object, V extends @Nullable Object, I extends Table<R, C, V>> Collector<T, ?, I>	toTable(Function<? super T, ? extends R> rowFunction, Function<? super T, ? extends C> columnFunction, Function<? super T, ? extends V> valueFunction, Supplier<I> tableSupplier) Returns a `Collector` that accumulates elements into a `Table` created using the specified supplier, whose cells are generated by applying the provided mapping functions to the input elements.
public static <T extends @Nullable Object, R extends @Nullable Object, C extends @Nullable Object, V extends @Nullable Object, I extends Table<R, C, V>> Collector<T, ?, I>	toTable(Function<? super T, ? extends R> rowFunction, Function<? super T, ? extends C> columnFunction, Function<? super T, ? extends V> valueFunction, BinaryOperator<V> mergeFunction, Supplier<I> tableSupplier) Returns a `Collector` that accumulates elements into a `Table` created using the specified supplier, whose cells are generated by applying the provided mapping functions to the input elements.
public static <R extends @Nullable Object, C extends @Nullable Object, V1 extends @Nullable Object, V2 extends @Nullable Object> Table<R, C, V2>	transformValues(Table<R, C, V1> fromTable, Function<? super V1, V2> function) Returns a view of a table where each value is transformed by a function.
public static <R extends @Nullable Object, C extends @Nullable Object, V extends @Nullable Object> Table<C, R, V>	transpose(Table<R, C, V> table) Creates a transposed view of a given table that flips its row and column keys.
public static <R extends @Nullable Object, C extends @Nullable Object, V extends @Nullable Object> RowSortedTable<R, C, V>	Returns: an unmodifiable view of the specified table unmodifiableRowSortedTable(RowSortedTable<R, ? extends C, ? extends V> the row-sorted table for which an unmodifiable view is to be returned table) Returns an unmodifiable view of the specified row-sorted table.
public static <R extends @Nullable Object, C extends @Nullable Object, V extends @Nullable Object> Table<R, C, V>	unmodifiableTable(Table<? extends R, ? extends C, ? extends V> table) Returns an unmodifiable view of the specified table.
private static <K extends @Nullable Object, V extends @Nullable Object> Function<Map<K, V>, Map<K, V>>	unmodifiableWrapper()
