oracle.dss.rules
Class RuleContext

java.lang.Object
java.util.Dictionary<K,V>
java.util.Hashtable
oracle.dss.rules.RuleContext

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map

public class RuleContext

extends java.util.Hashtable

implements java.io.Serializable

Information about an item in a Dataview. RuleContext objects are used by Rules to determine whether the Rule applies to the item.

RuleContext objects store data objects that contain information about the Dataview item. The fields in this class are the keys into the RuleContext.

To retrieve, for example, a QDR data object for this context, you would call the the get method of the superclass, passing RuleContext.QDR as the key.

Do not pass null parameters to the put or get methods of the Hashtable. If either parameter is null, the method throws a NullPointerException. It is the responsibility of the user of the RuleContext to ensure that this does not happen.

Method Detail

clone

public java.lang.Object clone()

Clones this RuleContext. This method creates a shallow copy.

Overrides:

clone in class java.util.Hashtable

Returns:

The clone of this RuleContext.

setStopAtFirstMatch

public void setStopAtFirstMatch(boolean v)

Specifies whether bundles of rules stop being run after a RuleBundle is run that has a Rule that applies and has been fired. Stopping at the first RuleBundle prevents rules that are in later rule bundles in the vector from changing the effect of the RuleBundle. Stopping at the first applicable rule also enhances performance.

Parameters:

v - true to stop running rule bundles after the first bundle that has an applicable rule, false to run all the rule bundles.

isStopAtFirstMatch

public boolean isStopAtFirstMatch()

Indicates whether bundles of rules stop being run after a RuleBundle is run that has a Rule that applies and has been fired. Stopping at the first RuleBundle prevents rules that are in later rule bundles in the vector from changing the effect of the RuleBundle. Stopping at the first applicable rule also enhances performance.

Returns:

true if rule bundles are not run after the first bundle that has an applicable rule, false if the all rule bundles are run.
