Method Detail

apply

ViewStateMachine.State apply(ViewStateMachine.TransitionState transition)

It changes the current state according to the provided transition state and returns the previous state.

Parameters:

transition - The provided transition state

Returns:

The previous state

init

void init(ViewStateMachine.State current)

It initializes the current state.

Parameters:

current - The current initial state

stateMachine

void stateMachine(boolean[] newState)

Sets the state of the components according to the encoded array.

Parameters:

newState - array of boolean states, one per component, in a predefined order. true means enabled.

stateMachine

void stateMachine(boolean[] which,
                  boolean[] newState)

Selectively sets the state of the components according to the encoded array.

Parameters:

which - array of booleans acting as a mask,one boolean per component. true means component changes state as specified in newState array.

newState - array of boolean states, one per component, in a predefined order. true means enabled.

stateMachineModal

boolean[] stateMachineModal(boolean[] which,
                            boolean[] newState)

Selectively sets the state of the components according to the encoded array and returns the array of the saved current state. The saved state can be used as input to the stateMachine(boolean[]) method call.

Parameters:

which - array of booleans acting as a mask,one boolean per component. true means component changes state as specified in newState array.

newState - array of boolean states, one per component, in a predefined order. true means enabled.

Returns:

saved state of all components
