Class logic.Action

   +----logic.Action

public class Action

extends Object

attribute

This is an attribute that is passed in and set with the "typical" constructor, following the default framework behavior.

MAIN_KEY

This String is used as a key in the default behavior of this class -- when the first constructor is used, attribute is set as value in a hashtable, using MAIN_KEY as key.

ud

object on which some action must be performed

updateVals

When rules are executed, this a table of update values for the Updateable object is obtained and set here

Action(Updateable, Hashtable)

This constructor handles all the more complicated scenarios in which more is required from an action then setting a single attribute.

Action(Updateable, Object)

This is the "default" constructor -- it handles the simple case in which the required action simply sets a value in the Updateable object.

execute()

What is provided here is default behavior.

getUd()

getUpdateVals()

setAttribute(Object)

setAttributesFromTable(Hashtable)

 protected Updateable ud

object on which some action must be performed

 protected Hashtable updateVals

When rules are executed, this a table of update values for the Updateable object is obtained and set here

 protected Object attribute

This is an attribute that is passed in and set with the "typical" constructor, following the default framework behavior. When this constructor is used the default behavior involves setting this attribute in the Updateable object

 public static final String MAIN_KEY

This String is used as a key in the default behavior of this class -- when the first constructor is used, attribute is set as value in a hashtable, using MAIN_KEY as key. The hashtable is passed to the Updateable instance and is unpacked using MAIN_KEY again.

 public Action(Updateable ud,
               Object attribute)

This is the "default" constructor -- it handles the simple case in which the required action simply sets a value in the Updateable object.

 public Action(Updateable ud,
               Hashtable attributes)

This constructor handles all the more complicated scenarios in which more is required from an action then setting a single attribute. When this constructor is used, it's necessary to override the execute() method

 public void execute()

What is provided here is default behavior. If the Action(Updateable, Object) constructor was used, then the action to be performed is simply to set a single attribute in the Updateable object. The default behavior for execute() given below does this, using MAIN_KEY as key and the already set ivar attribute as the value. If you need a more complicated action, this method needs to be overridden.

 public Updateable getUd()

 public Hashtable getUpdateVals()

 public void setAttribute(Object ob)

 public void setAttributesFromTable(Hashtable ht)
