java.lang.Object

com.netflix.astyanax.cql.reads.CqlRowQueryImpl<K,C>

Type Parameters:

K -

C -

All Implemented Interfaces:

com.netflix.astyanax.Execution<com.netflix.astyanax.model.ColumnList<C>>, com.netflix.astyanax.query.RowQuery<K,C>

public class CqlRowQueryImpl<K,C>
extends java.lang.Object
implements com.netflix.astyanax.query.RowQuery<K,C>

Impl for RowQuery that uses java driver. It manages all single row queries and also has support for pagination. All ColumnQuery and ColumnCountQuery(s) originate from this class. Note that the class acts more like a placeholder for the structure query context. The actual query construction is done by other classes like CFRowQueryGen and CFColumnQueryGen
