implements AbstractChangeNounPartActionCmd, AbstractSyncNounPartActionCmd

This abstract change noun part implementation is a default implementation of processing action expressions for change and sync requests. These action expressions represent the change of a particular noun part. The command is given the noun and list of action expressions to act upon the noun. This implementation will delegate to the approprate add, change or delete methods passing the object to perform the operation on and the additional control parameters. The purpose of this class is to simplify the implementation by only having to implement the logic assoicated with the add, change or delete operations.

Constructor Detail

AbstractChangeNounPartActionCmdImpl

public AbstractChangeNounPartActionCmdImpl()

Creates an instance of the abstract change noun part command.

Method Detail

addActionExpression

public final void addActionExpression(java.lang.Object noun,
                                      ActionExpression changeAction)

This method add the list of ActionExpression to perform against the specified noun. These change actions contain the the part of the noun to change and the operation associated with that part.

Specified by:

addActionExpression in interface AbstractChangeNounPartActionCmd

Parameters:

noun - The noun to apply the action expressions againsts.

changeAction - The action expressions to perform.

setPersistentObjects

public final void setPersistentObjects(java.util.Map persistentObjects)

This method sets the persistent objects that have been resolved by the controller and passed along to all commands involved with this requests. These persistent objects are saved at the end of executing the entire request.

Specified by:

setPersistentObjects in interface AbstractChangeNounPartActionCmd

Parameters:

persistentObjects - The persistent objects.

reset

public void reset()

This method resets the command so it can be reused.

Specified by:

reset in interface com.ibm.websphere.command.Command

Overrides:

reset in class com.ibm.websphere.command.CacheableCommandImpl

See Also:

CacheableCommandImpl.reset()

isReadyToCallExecute

public boolean isReadyToCallExecute()

This method will indicate if the command is ready to executed. The command is ready if the noun and action expressions have been set and they are not null.

Specified by:

isReadyToCallExecute in interface com.ibm.websphere.command.Command

Specified by:

isReadyToCallExecute in class com.ibm.websphere.command.TargetableCommandImpl

Returns:

Whether the nouns and acton expressions have been set.

performExecute

public void performExecute()
                    throws java.lang.Exception

This method iterates though the action expressions and calls the appropriate method to handle the action. If the action does not match the add(), change() or delete() methods, then handleAction() is called.

Specified by:

performExecute in interface com.ibm.websphere.command.TargetableCommand

Specified by:

performExecute in class com.ibm.websphere.command.TargetableCommandImpl

Throws:

java.lang.Exception - A problem occurred when performing the action expression.

validate

public void validate()
              throws AbstractApplicationException

This method iterates though the action expressions and calls the appropriate method to validate the action. If the action does not match the validateAdd(), validateChange() or validateDelete() methods, then validateAction() is called.

Specified by:

validate in interface AbstractChangeNounPartActionCmd

Throws:

AbstractApplicationException - There is invalid information specified with the business object document request which will prevent the request from executing.

See Also:

AbstractChangeNounPartActionCmd.validate()

isGeneric

public boolean isGeneric()

This method returns true if the command can be run as a generic user, otherwise false. The default implementation will return true.

Specified by:

isGeneric in interface AbstractChangeNounPartActionCmd

Returns:

true if the command can run as a generic user, otherwise false.
