DefaultAsyncMap

public DefaultAsyncMap(String address,
               String name,
               org.vertx.java.core.Vertx vertx)

Method Detail

name

public String name()

Description copied from interface: AsyncMap

Returns the map name.

Specified by:

name in interface AsyncMap<K,V>

Returns:

The map name.

put

public void put(K key,
       V value)

Description copied from interface: AsyncMap

Sets a key value in the map.

Specified by:

put in interface AsyncMap<K,V>

Parameters:

key - The key to set.

value - The value to set.

put

public void put(K key,
       V value,
       org.vertx.java.core.Handler<org.vertx.java.core.AsyncResult<V>> doneHandler)

Description copied from interface: AsyncMap

Sets a key value in the map.

Specified by:

put in interface AsyncMap<K,V>

Parameters:

key - The key to set.

value - The value to set.

doneHandler - An asynchronous handler to be called once complete. The handler will be called with the previous key value if any.

get

public void get(K key,
       org.vertx.java.core.Handler<org.vertx.java.core.AsyncResult<V>> resultHandler)

Description copied from interface: AsyncMap

Gets a key value from the map.

Specified by:

get in interface AsyncMap<K,V>

Parameters:

key - The key to get.

resultHandler - An asynchronous handler to be called with the result. If the key is not set then the result value will be null.

remove

Description copied from interface: AsyncMap

Removes a key from the map.

Specified by:

remove in interface AsyncMap<K,V>

Parameters:

key - The key to remove.

resultHandler - An asynchronous handler to be called with the removed value. If the key is not set then the result value will be null.

               org.vertx.java.core.Handler<org.vertx.java.core.AsyncResult<Boolean>> resultHandler)

Description copied from interface: AsyncMap

Checks whether the map contains a key.

Specified by:

containsKey in interface AsyncMap<K,V>

Parameters:

key - The key to check.
