All Implemented Interfaces:

Table<R,C,V>
```
@GwtCompatible
public abstract class ImmutableTable<R,C,V>
extends Object
```
An immutable Table with reliable user-specified iteration order. Does not permit null keys or values.
Note: Although this class is not final, it cannot be subclassed as it has no public or protected constructors. Thus, instances of this class are guaranteed to be immutable.

See the Guava User Guide article on immutable collections.

```
public static <R,C,V> ImmutableTable<R,C,V> of()
```
    Returns an empty immutable table.
  - of
```
public static <R,C,V> ImmutableTable<R,C,V> of(R rowKey,
                                               C columnKey,
                                               V value)
```
    Returns an immutable table containing a single cell.
  - copyOf
```
public static <R,C,V> ImmutableTable<R,C,V> copyOf(Table<? extends R,? extends C,? extends V> table)
```
    Returns an immutable copy of the provided table.
    The Table.cellSet() iteration order of the provided table determines the iteration ordering of all views in the returned table. Note that some views of the original table and the copied table may have different iteration orders. For more control over the ordering, create a ImmutableTable.Builder and call ImmutableTable.Builder.orderRowsBy(java.util.Comparator<? super R>), ImmutableTable.Builder.orderColumnsBy(java.util.Comparator<? super C>), and ImmutableTable.Builder.putAll(com.google.common.collect.Table<? extends R, ? extends C, ? extends V>)
    
    Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.
  - builder
```
public static <R,C,V> ImmutableTable.Builder<R,C,V> builder()
```
    Returns a new builder. The generated builder is equivalent to the builder created by the ImmutableTable.Builder.ImmutableTable.Builder() constructor.
  - 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<V> values()
```
    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,V> column(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.
    
    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<C> 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<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.
    
    Returns:
    
    a map view from each column key to a secondary map from row keys to values
  - row
```
public ImmutableMap<C,V> row(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.
    
    Parameters:
    
    rowKey - key of row to search for in the table
    
    Returns:
    
    the corresponding map from column keys to values
    
    Throws:
    
    NullPointerException - if rowKey is null
  - rowKeySet
```
public ImmutableSet<R> rowKeySet()

    Specified by:
    
    rowKeySet in interface Table<R,C,V>
    
    Returns:
    
    set of row keys
  - rowMap
```
public abstract ImmutableMap<R,Map<C,V>> rowMap()
```
    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.
    
    Returns:
    
    a map view from each row key to a secondary map from column keys to values
