public class RuleContext
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.

will most likely be used by a QDRDiscriminator
.
public static final java.lang.String DIMENSIONQDR
DIMENSIONQDR
. The DIMENSIONQDR
will most likely be used by a QDRDiscriminator
.
public static final java.lang.String POSITION
ComponentInfo
. The ComponentInfo
will most likely be used by a PositionDiscriminator
.
public static final java.lang.String NUMBER_VALUE
Number
. The Number
