Method Detail

contains

public boolean contains(java.lang.Object value)

Description copied from interface: RoutingTable

Tests if some key maps into the specified value in this Routing Table.

Specified by:

contains in interface RoutingTable

Parameters:

value - a value to search for.

Returns:

true if and only if some key maps to the value argument in this Routing Table as determined by the equals method; false otherwise.

See Also:

RoutingTable.containsKey(String), RoutingTable.containsValue(Object)

elements

public java.util.Enumeration elements()

Description copied from interface: RoutingTable

Returns an enumeration of the values in this Routing Table. Use the Enumeration methods on the returned object to fetch the elements sequentially.

Specified by:

elements in interface RoutingTable

Returns:

an enumeration of the values in this Routing Table.

See Also:

Enumeration, RoutingTable.keys(), RoutingTable.values()

keys

public java.util.Enumeration keys()

Description copied from interface: RoutingTable

Returns an enumeration of the keys in this Routing Table.

Specified by:

keys in interface RoutingTable

Returns:

an enumeration of the keys in this Routing Table.

See Also:

Enumeration, RoutingTable.elements()

isEmpty

public boolean isEmpty()

Description copied from interface: RoutingTable

Tests if this Routing Table maps no keys to values.

Specified by:

isEmpty in interface RoutingTable

Returns:

true if this Routing Table maps no keys to values; false otherwise.

get

public java.lang.Object get(java.net.URI key)

Description copied from interface: RoutingTable

Returns the value to which the specified key is mapped in this Routing Table.

Specified by:

get in interface RoutingTable

Returns:

the value to which the key is mapped in this Routing Table; null if the key is not mapped to any value in this Routing Table.

See Also:

RoutingTable.put(URI, Object)

containsValue

public boolean containsValue(java.lang.Object value)

Description copied from interface: RoutingTable

Returns true if this Routing Table maps one or more keys to this value.

Specified by:

containsValue in interface RoutingTable

Parameters:

value - value whose presence in this Routing Table is to be tested.

Returns:

true if this Routing Table maps one or more keys to the specified value.

clear

public void clear()

Description copied from interface: RoutingTable

Clears the Routing Table so that it contains no keys.

Specified by:

clear in interface RoutingTable

put

public java.lang.Object put(java.lang.String key,
                            java.lang.Object value)

Description copied from interface: RoutingTable

Maps the specified key to the specified value in this Routing Table. Neither the key nor the value can be null.

The value can be retrieved by calling the get method with a key that is equal to the original key.

Specified by:

put in interface RoutingTable

Parameters:

key - the Routing Table key.

value - the value.

Returns:

the previous value of the specified key in this Routing Table, or null if it did not have one.

See Also:

Object.equals(Object), RoutingTable.get(String)

values

public java.util.Collection values()

Description copied from interface: RoutingTable

Returns a Collection view of the values contained in this Routing Table. The Collection is backed by the Routing Table, so changes to the Routing Table are reflected in the Collection, and vice-versa. The Collection supports element removal (which removes the corresponding entry from the Routing Table), but not element addition.

Specified by:

values in interface RoutingTable

Returns:

a collection view of the values contained in this Routing Table.

containsKey

public boolean containsKey(java.lang.String key)

Description copied from interface: RoutingTable

Tests if the specified object is a key in this Routing Table.

Specified by:

containsKey in interface RoutingTable

Parameters:

key - possible key.

Returns:

true if and only if the specified object is a key in this Routing Table, as determined by the equals method; false otherwise.

See Also:

RoutingTable.contains(Object)

putAll

public void putAll(RoutingTable t)

Description copied from interface: RoutingTable

Copies all of the mappings from the specified Map to this Routing Table These mappings will replace any mappings that this Routing Table had for any of the keys currently in the specified Routing Table.

Specified by:

putAll in interface RoutingTable

Parameters:

t - Mappings to be stored in this Routing Table.

put

public java.lang.Object put(java.net.URI key,
                            java.lang.Object value)

The value can be retrieved by calling the get method with a key that is equal to the original key.

Specified by:

put in interface RoutingTable

Parameters:

key - the Routing Table key.

value - the value.

Returns:

the number of keys in this Routing Table.

remove
