public final class AnchorConfigWithKeyExtractor
extends AnchorConfig

Represents the anchor definition (the object part) for the anchors that have ONLY keyExtractor specified. It is mutually exclusive with AnchorConfigWithExtractor The anchors may be specified in the following ways: In the following, the fields lateralViewParameters, type, and default are optional.

 
 <anchor name 1>: {
   source: <source name>
   keyExtractor: <full extractor class name>
    lateralViewParameters: {
      lateralViewDef: <view def expr>
      lateralViewItemAlias: <item alias>
      lateralViewFilter: <filter expr>
    }
   features: {
     <feature name>: {
       def: <feature expression>,
       type: <feature type>,
       default: <default value>
     }
     ...
   }
 }

 <anchor name 2>: {
   source: <source name 2>
   keyExtractor: <full extractor class name>
   features: {
     <feature name>: <feature expression>,
     ...
   }
 }
 

 
 <anchor name 3>: {
   source: <source name>
   keyExtractor: <full extractor class name>
   features: {
     <feature name>: {
       def.sqlExpr: <feature expression>,
