Method Detail

get

void get(K k,
         Handler<AsyncResult<V>> resultHandler)

Get a value from the map, asynchronously.

Parameters:

k - The key

resultHandler - - this will be called some time later with the async result.

put

void put(K k,
         V v,
         Handler<AsyncResult<Void>> completionHandler)

Put a value in the map, asynchronously.

Parameters:

k - The key

v - The value

completionHandler - - this will be called some time later to signify the value has been put

put

void put(K k,
         V v,
         long timeout,
         Handler<AsyncResult<Void>> completionHandler)

putIfAbsent

void putIfAbsent(K k,
                 V v,
                 Handler<AsyncResult<V>> completionHandler)

putIfAbsent

void putIfAbsent(K k,
                 V v,
                 long timeout,
                 Handler<AsyncResult<V>> completionHandler)

remove

void remove(K k,
            Handler<AsyncResult<V>> resultHandler)

Remove a value from the map, asynchronously.

Parameters:

k - The key

resultHandler - - this will be called some time later to signify the value has been removed

removeIfPresent

void removeIfPresent(K k,
                     V v,
                     Handler<AsyncResult<Boolean>> resultHandler)

replace

void replace(K k,
             V v,
             Handler<AsyncResult<V>> resultHandler)

replaceIfPresent

void replaceIfPresent(K k,
                      V oldValue,
                      V newValue,
                      Handler<AsyncResult<Boolean>> resultHandler)

clear

void clear(Handler<AsyncResult<Void>> resultHandler)

size

void size(Handler<AsyncResult<Integer>> resultHandler)
