Method Detail

getAssemblyLine

AssemblyLine getAssemblyLine()
                      throws DIException

Returns an AssemblyLine instance.

Returns:

this AssemblyLine.

Throws:

DIException - if an error occurs while retrieving the AssemblyLine.

executeCycle

Entry executeCycle(Entry aEntry,
                   boolean aProcessTCB)
            throws DIException

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

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

Entry executeCycle(Entry aEntry)
            throws DIException

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

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

Entry executeCycle()
            throws DIException

Executes an AssemblyLine cycle with null work Entry attribute.

Returns:

the work entry at the end of the cycle

Throws:

DIException - if an error occurs while executing the AssemblyLine.

eval

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.
