Class LookupDimension

java.lang.Object

com.yahoo.bard.webservice.data.dimension.impl.KeyValueStoreDimension

com.yahoo.bard.webservice.data.dimension.impl.LookupDimension

All Implemented Interfaces:

Dimension, ExtractionFunctionDimension

public class LookupDimension
extends KeyValueStoreDimension
implements ExtractionFunctionDimension

LookupDimension creates a Look up dimension based on the namespace chain.

LookupDimension is essentially a special case of RegisteredLookupDimension using namespace. Hence this class ONLY applies to the Druid namespace lookup serialization. See http://druid.io/docs/latest/querying/dimensionspecs.html#lookup-extraction-function for more details.
