Method Detail

changeVariables

public void changeVariables(Object source,
                            Map<String,Object> variables)

Description copied from interface: VariableOwner

Called when one or more variables handled by the implementing class are changed.

Specified by:

changeVariables in interface VariableOwner

Parameters:

source - the Source of the variable change. This is the origin of the event. For example in Web Adapter this is the request.

variables - the Mapping from variable names to new variable values.

isEnabled

public boolean isEnabled()

Description copied from interface: VariableOwner

Tests if the variable owner is enabled or not. The terminal should not send any variable changes to disabled variable owners.

Specified by:

isEnabled in interface VariableOwner

Returns:

true if the variable owner is enabled, false if not

isImmediate

public boolean isImmediate()

Description copied from interface: VariableOwner

Tests if the variable owner is in immediate mode or not. Being in immediate mode means that all variable changes are required to be sent back from the terminal immediately when they occur.

Note: VariableOwner does not include a set- method for the immediateness property. This is because not all VariableOwners wish to offer the functionality. Such VariableOwners are never in the immediate mode, thus they always return false in VariableOwner.isImmediate().

Specified by:

isImmediate in interface VariableOwner

Returns:

true if the component is in immediate mode, false if not.
