hello.
It looks like peerAssemblyLoadingMode flag doesn’t work correctly in case
of CacheEntryEventFilter:
As an example:
1) This code works fine and I see “Hello world” on the server console. It
means that HelloAction class was successfully transferred to server.
class Program
{
static void Main(string[] args)
{
using (var ignite = Ignition
.StartFromApplicationConfiguration())
{
var remotes = ignite.GetCluster().ForRemotes();
remotes.GetCompute().Broadcast(newHelloAction());
}
}
class HelloAction : IComputeAction
{
public void Invoke()
{
Console.WriteLine("Hello, World!");
}
}
}
2) But this code that sends the filter class to the remote server node
generates an error and I receive 4 entries of Employee instead of 2 as
expected:
class Program
{
public class Employee
{
public Employee(string name, long salary)
{
Name = name;
Salary = salary;
}
[QuerySqlField]
public string Name { get; set; }
[QuerySqlField]
public long Salary { get; set; }
public override string ToString()
{
return string.Format("{0} [name={1}, salary={2}]", typeof(
Employee).Name, Name, Salary);
}
}
class EmployeeEventListener :ICacheEntryEventListener<int, Employee>
{
public void OnEvent(IEnumerable<ICacheEntryEvent<int, Employee>>
evts)
{
foreach(var evt in evts)
Console.WriteLine(evt.Value);
}
}
class EmployeeEventFilter :ICacheEntryEventFilter<int, Employee>
{
public bool Evaluate(ICacheEntryEvent<int,Employee> evt)
{
return evt.Value.Salary > 5000;
}
}
static void Main(string[] args)
{
using (var ignite = Ignition
.StartFromApplicationConfiguration())
{
var employeeCache = ignite.GetOrCreateCache<int, Employee>(
new CacheConfiguration("employee", newQueryEntity(typeof
(int), typeof(Employee))) { SqlSchema = "PUBLIC" });
var query = new ContinuousQuery<int,Employee>(new
EmployeeEventListener())
{
Filter = new EmployeeEventFilter()
};
var queryHandle = employeeCache.QueryContinuous(query);
employeeCache.Put(1, newEmployee("James Wilson", 1000));
employeeCache.Put(2, new Employee("Daniel Adams", 2000));
employeeCache.Put(3, newEmployee("Cristian Moss", 7000));
employeeCache.Put(4, newEmployee("Allison Mathis", 8000));
Console.WriteLine("Press any key...");
Console.ReadKey();
}
}
}
