Method Detail

containsRow

public boolean containsRow(java.lang.Object rowKey)

Description copied from interface: Table

Returns true if the table contains a mapping with the specified row key.

Specified by:

containsRow in interface Table<R,C,V>

Parameters:

rowKey - key of row to search for

containsColumn

public boolean containsColumn(java.lang.Object columnKey)

Description copied from interface: Table

Returns true if the table contains a mapping with the specified column.

Specified by:

containsColumn in interface Table<R,C,V>

Parameters:

columnKey - key of column to search for

rowKeySet

public java.util.Set<R> rowKeySet()

Description copied from interface: Table

Returns a set of row keys that have one or more values in the table. Changes to the set will update the underlying table, and vice versa.

Specified by:

rowKeySet in interface Table<R,C,V>

Returns:

set of row keys

columnKeySet

public java.util.Set<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

containsValue

public boolean containsValue(java.lang.Object value)

Description copied from interface: Table

Returns true if the table contains a mapping with the specified value.

Specified by:

containsValue in interface Table<R,C,V>

Parameters:

value - value to search for

contains

public boolean contains(java.lang.Object rowKey,
                        java.lang.Object columnKey)

Description copied from interface: Table

Returns true if the table contains a mapping with the specified row and column keys.

Specified by:

contains in interface Table<R,C,V>

Parameters:

rowKey - key of row to search for

columnKey - key of column to search for

get

public V get(java.lang.Object rowKey,
             java.lang.Object columnKey)

Description copied from interface: Table

Returns the value corresponding to the given row and column keys, or null if no such mapping exists.

Specified by:

get in interface Table<R,C,V>

Parameters:

rowKey - key of row to search for

columnKey - key of column to search for

isEmpty

public boolean isEmpty()

Description copied from interface: Table

Returns true if the table contains no mappings.

Specified by:

isEmpty in interface Table<R,C,V>

clear

public void clear()

Description copied from interface: Table

Removes all mappings from the table.

Specified by:

clear in interface Table<R,C,V>

remove

public V remove(java.lang.Object rowKey,
                java.lang.Object columnKey)

Description copied from interface: Table

Removes the mapping, if any, associated with the given keys.

Specified by:

remove in interface Table<R,C,V>

Parameters:

rowKey - row key of mapping to be removed

columnKey - column key of mapping to be removed

Returns:

the value previously associated with the keys, or null if no such value existed

put

public V put(R rowKey,
             C columnKey,
             V value)

Description copied from interface: Table

Associates the specified value with the specified keys. If the table already contained a mapping for those keys, the old value is replaced with the specified value.

Specified by:

put in interface Table<R,C,V>

Parameters:

rowKey - row key that the value should be associated with

columnKey - column key that the value should be associated with

value - value to be associated with the specified keys

Returns:

the value previously associated with the keys, or null if no mapping existed for the keys

putAll

public void putAll(Table<? extends R,? extends C,? extends V> table)

Description copied from interface: Table

Copies all mappings from the specified table to this table. The effect is equivalent to calling Table.put(R, C, V) with each row key / column key / value mapping in table.

Specified by:

putAll in interface Table<R,C,V>

Parameters:

table - the table to add to this table

cellSet

public java.util.Set<Table.Cell<R,C,V>> cellSet()
