AssemblyLineHandlerImpl

public AssemblyLineHandlerImpl(AssemblyLine aAssemblyLine,
                               AssemblyLine aRawAssemblyLine,
                               SessionImpl aSession)
                        throws DIException

Constructor

Parameters:

aAssemblyLine - AssemblyLine instance

aRawAssemblyLine - AssemblyLine instance

aSession - SessionImpl instance

Throws:

DIException - if some of the parameters is null.

Method Detail

getAssemblyLine

public AssemblyLine getAssemblyLine()
                             throws DIException

Returns an AssemblyLine instance.

Specified by:

getAssemblyLine in interface AssemblyLineHandler

Returns:

this AssemblyLine.

Throws:

DIException - if an error occurs while retrieving the AssemblyLine.

executeCycle

public Entry executeCycle(Entry aEntry,
                          boolean aProcessTCB)
                   throws DIException

Executes an AssemblyLine cycle. If an Entry is provided then it becomes the work entry.

Specified by:

executeCycle in interface AssemblyLineHandler

Parameters:

aEntry - the work entry to use, or null to use an empty work entry/iterator entry.

aProcessTCB - if true, the AL's call/return attribute maps are applied to the provided entry and returned entry.

Returns:

the work entry at the end of the cycle.

Throws:

DIException - if an error occurs while executing the AssemblyLine.

executeCycle

public Entry executeCycle(Entry aEntry)
                   throws DIException

Executes an AssemblyLine cycle. If an Entry is provided then it becomes the work entry.

Specified by:

executeCycle in interface AssemblyLineHandler

Parameters:

aEntry - the work entry to use, or null to use an empty work entry/iterator entry.

Returns:

the work entry at the end of the cycle.

Throws:

DIException - if an error occurs while executing the AssemblyLine.

executeCycle

public Entry executeCycle()
                   throws DIException

Executes an AssemblyLine cycle with null work Entry attribute.

Specified by:

executeCycle in interface AssemblyLineHandler

Returns:

the work entry at the end of the cycle

Throws:

DIException - if an error occurs while executing the AssemblyLine.

close

public void close()
           throws DIException

Closes an AssemblyLine.

Specified by:

close in interface AssemblyLineHandler

Throws:

DIException - if an error occurs while closing the AssemblyLine.

eval

public java.io.Serializable eval(java.lang.String script)
                          throws DIException

Evaluates the passed in as parameter script in the context of this AssemblyLine. You can access all the script beans defined in the scope of this AssemblyLine.

Specified by:
