IMap(TKey, TValue).PutAsync Method (TKey, TValue)

IMapTKey, TValuePutAsync Method (TKey, TValue)

Hazelcast .Net Client Class Library

Asynchronously puts the given key and value.

Namespace: Hazelcast.Core
Assembly: Hazelcast.Net (in Hazelcast.Net.dll) Version: 3.8.2

Syntax

Task<TValue> PutAsync(
	TKey key,
	TValue value
)

Function PutAsync ( 
	key As TKey,
	value As TValue
) As Task(Of TValue)

Task<TValue>^ PutAsync(
	TKey key, 
	TValue value
)

abstract PutAsync : 
        key : 'TKey * 
        value : 'TValue -> Task<'TValue>

Parameters

key: Type: TKey
the key of the map entry
value: Type: TValue
the new value of the map entry

Return Value

Type: TaskTValue
Task<V> from which the old value of the key can be retrieved.

Remarks

Asynchronously puts the given key and value.

Copy

Task<V> task = map.PutAsync(key, value);
// do some other stuff, when ready get the result
V oldValue = task.Result;

Task.Result will block until the actual map.Put() completes. If the application requires timely response, then task.Wait(timeout) can be used.

Copy

try
{
    Task<V> task = map.PutAsync(key, value);
    if(task.Wait(TimeSpan.FromMilliseconds(40)))
    {
       V value = task.Result; 
    }
    else
    {
     //Result not ready
    }

ExecutionException is never thrown.

Warning:

This method uses GetHashCode and Equals of binary form of the key, not the actual implementations of GetHashCode and Equals defined in key's class.
