Constructor Detail

AttributeMapComponent

public AttributeMapComponent(AssemblyLine parent,
                             java.lang.String name,
                             ALMappingConfig config)
                      throws java.lang.Exception

Constructor for the AttributeMapComponent object

Parameters:

parent - The AssemblyLine that contains this AttributeMapComponent

name - The name of this component

config - The configuration for this component

Throws:

java.lang.Exception - Any Exception that might occur

Method Detail

initialize

public void initialize()
                throws java.lang.Exception

This method creates the AttributeMapping for this component

Overrides:

initialize in class AssemblyLineComponent

Throws:

java.lang.Exception - Any Exception that might be thrown

willExecute

public boolean willExecute(Entry work)
                    throws java.lang.Exception

This method always returns true

Overrides:

willExecute in class AssemblyLineComponent

Parameters:

work - The work Entry

Returns:

always true

Throws:

java.lang.Exception - Any exception thrown by the executed hook

getConfiguration

public ConnectorConfig getConfiguration()

Returns the configuration for this component

Overrides:

getConfiguration in class AssemblyLineComponent

Returns:

the configuration for this component

getType

public int getType()

Returns the type of this component

Overrides:

getType in class AssemblyLineComponent

Returns:

ServerConstants.TYPE_ATTRIBUTEMAP

add

public void add(Entry meta)
         throws java.lang.Exception

Does the attribute mapping in every cycle

Overrides:

add in class AssemblyLineComponent

Parameters:

meta - The work Entry

Throws:

java.lang.Exception - the component is not initialized or the underlying Connector raised an error or some of the user-defined hooks raised an error

handleException

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

Handles any Exception. Since Attribute Maps don't have hooks, this method just rethrows the Exception

Overrides:

handleException in class AssemblyLineComponent

Parameters:

oper - The operation that was performed. Ignored

e - The Throwable that was thrown

meta - The work Entry

Throws:

java.lang.Exception - Rethrows the Throwable, if necessary wrapped in an Exception

trigger

public boolean trigger(java.lang.String oper,
                       Entry work,
                       Entry conn)

Performs any hook. Since there are no hooks, this method is never called

Overrides:

trigger in class AssemblyLineComponent

Parameters:

oper - The operation that was performed

work - The work Entry

conn - The conn Entry

Returns:

always false

trigger

public boolean trigger(java.lang.String oper,
                       Entry work)

Performs any hook. Since there are no hooks, this method is never called

Overrides:

trigger in class AssemblyLineComponent

Parameters:

oper - The operation that was performed

work - The work Entry

Returns:

always false

close

public void close()
           throws java.lang.Exception

This method closes the AttributeMapComponent

Overrides:

close in class AssemblyLineComponent

Throws:

java.lang.Exception
