Constructor Detail

EndLoopComponent

public EndLoopComponent(AssemblyLine parent,
                        LoopComponent loop)

This constructor is used to insert the EndLoop component in the AL

Parameters:

parent - The AssemblyLine this EndLoopComponent is part of

loop - The LoopComponent that we end

Method Detail

initialize

public void initialize()

This method does nothing.

Overrides:

initialize in class AssemblyLineComponent

willExecute

public boolean willExecute(Entry work)

This method always returns true.

Overrides:

willExecute in class AssemblyLineComponent

Parameters:

work - an Entry object

Returns:

true

getType

public int getType()

Return the type of this component

Overrides:

getType in class AssemblyLineComponent

Returns:

ServerConstants.TYPE_LOOP

add

public void add(Entry meta)
         throws Exception

Tells the AssemblyLine to go back to the start of the loop

Overrides:

add in class AssemblyLineComponent

Parameters:

meta - The work Entry. Ignored

Throws:

Exception - if we cannot go back to the start of the loop

handleException

public void handleException(String oper,
                            Throwable e,
                            Entry meta)
                     throws Exception

Handles Exceptions by rethrowing them

Overrides:

handleException in class AssemblyLineComponent

Parameters:
