public class Action

extends Object

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.

attribute

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

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

logic.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.

logic.Action(Updateable, Hashtable)

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

execute()

What is provided here is default behavior.

getUd()

getUpdateVals()

setAttribute(Object)

setAttributesFromTable(Hashtable)

public static final java.lang.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.

protected java.lang.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

protected logic.Updateable ud

object on which some action must be performed

protected java.util.Hashtable updateVals

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

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 logic.Updateable getUd()

public java.util.Hashtable getUpdateVals()

public void setAttribute(Object ob)

public void setAttributesFromTable(Hashtable ht)
