.NET Client
You can use native .NET client to connect to Hazelcast nodes. All you need is to add HazelcastClient3x.dll into your .NET project references. The API is very similar to Java native client. Sample code is shown below.
using Hazelcast.Config;
using Hazelcast.Client;
using Hazelcast.Core;
using Hazelcast.IO.Serialization;
using System.Collections.Generic;
namespace Hazelcast.Client.Example
{
public class SimpleExample
{
public static void Test()
{
var clientConfig = new ClientConfig();
clientConfig.GetNetworkConfig().AddAddress( "10.0.0.1" );
clientConfig.GetNetworkConfig().AddAddress( "10.0.0.2:5702" );
// Portable Serialization setup up for Customer Class
clientConfig.GetSerializationConfig()
.AddPortableFactory( MyPortableFactory.FactoryId, new MyPortableFactory() );
IHazelcastInstance client = HazelcastClient.NewHazelcastClient( clientConfig );
// All cluster operations that you can do with ordinary HazelcastInstance
IMap<string, Customer> mapCustomers = client.GetMap<string, Customer>( "customers" );
mapCustomers.Put( "1", new Customer( "Joe", "Smith" ) );
mapCustomers.Put( "2", new Customer( "Ali", "Selam" ) );
mapCustomers.Put( "3", new Customer( "Avi", "Noyan" ) );
ICollection<Customer> customers = mapCustomers.Values();
foreach (var customer in customers)
{
//process customer
}
}
}
public class MyPortableFactory : IPortableFactory
{
public const int FactoryId = 1;
public IPortable Create( int classId ) {
if ( Customer.Id == classId )
return new Customer();
else
return null;
}
}
public class Customer : IPortable
{
private string name;
private string surname;
public const int Id = 5;
public Customer( string name, string surname )
{
this.name = name;
this.surname = surname;
}
public Customer() {}
public int GetFactoryId()
{
return MyPortableFactory.FactoryId;
}
public int GetClassId()
{
return Id;
}
public void WritePortable( IPortableWriter writer )
{
writer.WriteUTF( "n", name );
writer.WriteUTF( "s", surname );
}
public void ReadPortable( IPortableReader reader )
{
name = reader.ReadUTF( "n" );
surname = reader.ReadUTF( "s" );
}
}
}
Client Configuration
Hazelcast .NET client can be configured via API or XML. To start the client, a configuration can be passed or can be left empty to use default values.
NOTE: .NET and Java clients are similar in terms of configuration. Therefore, you can refer to Java Client section for configuration aspects. For information on .NET API documentation, please refer to the API document provided along with the Hazelcast Enterprise license.
Client Startup
After configuration, one can obtain a client using one of the static methods of Hazelcast like as shown below.
IHazelcastInstance client = HazelcastClient.NewHazelcastClient(clientConfig);
...
IHazelcastInstance defaultClient = HazelcastClient.NewHazelcastClient();
...
IHazelcastInstance xmlConfClient = Hazelcast
.NewHazelcastClient(@"..\Hazelcast.Net\Resources\hazelcast-client.xml");
IHazelcastInstance interface is the starting point where all distributed objects can be obtained using it.
var map = client.GetMap<int,string>("mapName");
...
var lock= client.GetLock("thelock");
.NET Client has following distributed objects:
IMap<K,V>IMultiMap<K,V>IQueue<E>ITopic<E>IHList<E>IHSet<E>IIdGeneratorILockISemaphoreICountDownLatchIAtomicLongITransactionContextITransactionContext can be used to obtain;
