All Implemented Interfaces:

Composable, MultiPhased, DynamicActionSequence

@NonBrowserable
public class IfThenElse
extends SinglePhaseAction
implements DynamicActionSequence

IfThenElse is a subclass of SinglePhaseAction which performs actions according to the evaluation result of specified function. If this function returns something different from null or false then the result is positive; otherwise negative.

IfThenElse maintains two lists of actions internally:

• positive action list - list of actions to perform for positive result
• negative action list - list of actions to perform for negative result

Constructor Details

IfThenElse

public IfThenElse(Function<ActionComposer,?> evalFunction,
 List<Composable> positiveActionList,
 List<Composable> negativeActionList)

Create an action representing if-then-else condition.

Parameters:

evalFunction - the function to evaluate

positiveActionList - the actions to perform if the result is true

negativeActionList - the actions to perform if the result is false

Method Details

performSinglePhase

protected void performSinglePhase()

Description copied from class: SinglePhaseAction

Perform single-phased browser action.

Specified by:

performSinglePhase in class SinglePhaseAction

toString

public String toString()

Overrides:

toString in class MultiPhaseAction

isFail

public boolean isFail()

Description copied from class: MultiPhaseAction

When the action is marked as failed(ActionState.COMPLETE_WITH_ERROR), then it's called fail.

Specified by:

isFail in interface Composable

Overrides:

isFail in class MultiPhaseAction

Returns:

true if the action is failed; false otherwise

getErrors

public List<Exception> getErrors()

Description copied from interface: Composable

Get the errors occurred during execution.

Specified by:

getErrors in interface Composable

Overrides:

getErrors in class MultiPhaseAction

Returns:

the errors as a list of Exception

addToHead

public DynamicActionSequence addToHead(Composable action)

Add action to the head of positive or negative list. It depends on the evaluation result and does nothing before evaulation.

Specified by:

addToHead in interface DynamicActionSequence

Parameters:

action - action to add

Returns:

self reference

addToTail

public DynamicActionSequence addToTail(Composable action)

Add action to the tail of positive or negative list. It depends on the evaluation result and does nothing before evaulation.

Specified by:

addToTail in interface DynamicActionSequence

Parameters:

action - action to add

Returns:

self reference

addToPosition

public DynamicActionSequence addToPosition(Composable action,
 int position)

Add action to the the specified position of positive or negative list. It depends on the evaluation result and does nothing before evaulation.

Specified by:

addToPosition in interface DynamicActionSequence

Parameters:

action - action to add

position - the position(zero-based) to add given action

Returns:

self reference
