public abstract class StateService : RadDockService, IDisposable, INotifyPropertyChanged, INotifyPropertyChangingEx

Constructors

StateService()

Default constructor.

Declaration
public StateService()

Properties

AvailableAtDesignTime

Determines whether the service is available at design-time. False by default.

Declaration
public virtual bool AvailableAtDesignTime { get; }
Property Value
System.Boolean

Context

Gets the context associated with the current operation. This member is valid only while the Service is started or paused.

Declaration
public object Context { get; }
Property Value
System.Object

State

Gets the current state of the service.

Declaration
public ServiceState State { get; }
Property Value

Methods

Abort()

Aborts the current operation without applying any changes.

Declaration
protected virtual void Abort()

CanStart(Object)

Determines whether the service may be started. Validation is as follows:

  1. Check whether Enabled is true.
  2. Check the context through IsContextValid method. An exception is thrown if context is invalid.
  3. Checks the current state - it should be Initial or Stopped.
Declaration
protected virtual bool CanStart(object context)
Parameters
System.Object context

Returns
System.Boolean

Commit()

Ends the current operation and applies all changes.

Declaration
protected virtual void Commit()

IsContextValid(Object)

Evaluates the provided context. Some services may not operate without certain context provided.

Declaration
protected virtual bool IsContextValid(object context)
Parameters
System.Object context

Returns
System.Boolean

OnDockManagerChanged()

Provides additional processing when a change in the owning RadDock instance occurs.

Declaration
protected override void OnDockManagerChanged()
Overrides
RadDockService.OnDockManagerChanged()

OnEnabledChanged()

Provides additional processing for a change in the Enabled state.

Declaration
protected override void OnEnabledChanged()
Overrides
RadDockService.OnEnabledChanged()

OnStarted()

Notifies that the service has been successfully started. Allows inheritors to perform some additional logic upon start.

Declaration
protected virtual void OnStarted()

OnStarting(StateServiceStartingEventArgs)

Notifies that a start request has occured. Cancelable.

Declaration
protected virtual void OnStarting(StateServiceStartingEventArgs e)
Parameters
StateServiceStartingEventArgs e

OnStopped()

Notifies that a running operation has stopped. Allows inheritors to perform some additional logic upon stop.

Declaration
protected virtual void OnStopped()

OnStopping(StateServiceStoppingEventArgs)

Notifies that a stop request has occured. Cancelable.

Declaration
protected virtual void OnStopping(StateServiceStoppingEventArgs e)
Parameters
StateServiceStoppingEventArgs e
