IOpenable

Inherits: IClosable

Description

The IOpenable interface allows you to create components with explicit opening and closing.

Important points

• For components that perform opening on demand, consider using the IClosable interface instead.

Instance methods

IsOpen

Checks if the component is open.

bool IsOpen()

• returns: bool - true if the component is open and false otherwise.

OpenAsync

Opens the component.

Task OpenAsync(IContext context)

• context: IContext - (optional) a context to trace execution through a call chain.

Examples

class MyPersistence: IOpenable 
{
    private object _client;
    ...
    public bool IsOpen()
    {
        return this._client != null;
    }
    public void Open(IContext context)
    {
        if (this.isOpen())
        {
            return;
        }
        ...
    }
    public void Close(IContext context)
    {
        if (this._client != null)
        {
            this._client.Close();
            this._client = null;
        }
    }
    ...
}
