public class D2WStatelessComponent

extends D2WComponent

The D2WStatelessComponent class represents a stateless Direct to Web component. For a stateless component, a single instance is shared between multiple sessions. Many property-level components are stateless.

Constructor Detail

D2WStatelessComponent

public D2WStatelessComponent(WOContext aContext)

Creates an instance of D2WStatelessComponent with the specified context.

Parameters:

aContext - instance of WOContext

See Also:

D2WComponent.D2WComponent(WOContext)

Method Detail

d2wContext

public D2WContext d2wContext()

Provides access to the local instance of D2WContext. In a stateless component, the local instance, once set, does not change until the component has been reset.

Overrides:

d2wContext in class D2WComponent

Returns:

instance of D2WContext

See Also:

reset(), D2WComponent.d2wContext()

isStateless

public boolean isStateless()

Indicates that the component is stateless. Returns true for D2WStatelessComponent and its subclasses.

Overrides:

isStateless in class WOComponent

Returns:

true

See Also:

WOComponent.isStateless()

localContext

public D2WContext localContext()

Deprecated.

The method localContext has been deprecated. Use the method d2wContext instead.

Overrides:

localContext in class D2WComponent

Returns:

instance of D2WContext

See Also:

d2wContext()

object

public EOEnterpriseObject object()

Provides access to the local instance of EOEnterpriseObject. In a stateless component, the local instance, once set, does not change until the component has been reset.

Overrides:

object in class D2WComponent

Returns:

instance of EOEnterpriseObject

See Also:

reset(), D2WComponent.object()

reset

public void reset()

Resets the component.

The current implementation clears the local instance of D2WContext and the local instance of EOEnterpriseObject.

The implementation is subject to change in future releases.

Overrides:

reset in class WOComponent

d2wContext(), object()
