Class EndBranchComponent

java.lang.Object
  com.ibm.di.server.AssemblyLineComponent
      com.ibm.di.server.EndBranchComponent

All Implemented Interfaces:

java.util.Map

public class EndBranchComponent
extends AssemblyLineComponent

The EndBranchComponent is an internal component that is associated with a BranchComponent. Its job is to check if we are in an if/else-if/else construct and skip any else-if/else type branch components based on the execute status of the associated BranchComponent.

Constructor Detail

EndBranchComponent

public EndBranchComponent(AssemblyLine parent,
                          BranchingComponent bc)

The Constructor for the EndBranchComponent

Parameters:

parent - The AssemblyLine that contains this EndBranchComponent

bc - The BranchingComponent that this is an end for

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. Our test is performed in the add operation.

Overrides:

willExecute in class AssemblyLineComponent

Parameters:

work - The work Entry. Not used.

Returns:

true

getType

public int getType()

This method returns the AL component type (ServerConstants.TYPE_BRANCH)

Overrides:

getType in class AssemblyLineComponent

Returns:

The type value (ServerConstants.TYPE_BRANCH)

add

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

This method is called by the hosting AssemblyLine. Check for if/else-if/else construct and set the next connector to execute based on branch type and execution status.

Overrides:

add in class AssemblyLineComponent

Parameters:

meta - The work entry (not used)

Throws:

java.lang.Exception - if a problem occurs

getParentBranchType

public int getParentBranchType()

Returns the type of the original branch to which this end branch belongs.

Returns:

the type of the parrent branch

handleException

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

Any errors during execution of add() ends up here. We don't have error hooks so we just rethrow the exception.

Overrides:

handleException in class AssemblyLineComponent

Parameters:

oper - Not used.

e - Exception

meta - Not used.

Throws:

java.lang.Exception - The "e" exception

trigger

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

NOOP. This component has no triggers.

Overrides:

trigger in class AssemblyLineComponent

Parameters:

oper - Not used.

work - Not used.

conn - Not used.

Returns:

false

trigger

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

NOOP. This component has no triggers.

Overrides:

trigger in class AssemblyLineComponent

Parameters:

oper - Not used.

work - Not used.

Returns:

false

close

public void close()
           throws java.lang.Exception

Release resources.

Overrides:

close in class AssemblyLineComponent

Throws:

java.lang.Exception - None
