Constructor Details

SequenceStateMachine

public SequenceStateMachine()

Constructor for SequenceStateMachine.

Method Details

newApplication

public static final SequenceStateMachine newApplication(String name,
 double timeout,
 String[] names)

newApplication.

Parameters:

name - a String object

timeout - a double

names - an array of String objects

Returns:

a SequenceStateMachine object

configure

public void configure(String name,
 org.apache.commons.configuration.HierarchicalConfiguration config)

Configures the internals of this application, provides reference to configuration with root inside applications tag. Server structure is not yet initialized, so does not have reference to Database, the Database reference will be available during activate call.

Specified by:

configure in interface Application

Overrides:

configure in class StateMachine

Parameters:

name - a String object

config - configuration with room inside application tag.

activate

public void activate()

Application has now reference to Database. Application might want to connect to other records on this server or PVs on other servers. This can not be done until all records from configuration has been loaded. Call to this method signals application that records has been loaded and linking to other values can be commenced.

Specified by:

activate in interface Application

Overrides:

activate in class StateMachine

updateProgress

public void updateProgress()

updateProgress.

updateState

public void updateState()

updateState.

stateMachinePrepare

public void stateMachinePrepare()

stateMachinePrepare.

Overrides:

stateMachinePrepare in class StateMachine

stateMachineActivate

public void stateMachineActivate(boolean dryrun)

Activates state machine. If this state machine is in dry-run mode or dry-run parameter with true is called, then this step is activate in dry-run mode.

Overrides:

stateMachineActivate in class StateMachine

Parameters:

dryrun - dry-run mode request

stateMachineAbort

public void stateMachineAbort()

stateMachineAbort.

Overrides:

stateMachineAbort in class StateMachine

setState

public void setState(StateMachine.State st)

setState.

Overrides:

setState in class StateMachine

Parameters:

st - a StateMachine.State object
