java.lang.Object

com.netflix.astyanax.cql.CqlAbstractExecutionImpl<R>

Type Parameters:

R -

All Implemented Interfaces:

com.netflix.astyanax.Execution<R>

public abstract class CqlAbstractExecutionImpl<R>
extends java.lang.Object
implements com.netflix.astyanax.Execution<R>

Abstract class that encapsulates the functionality for executing an operations using the native protocol based java driver Note that class provides only the operation agnostic functionality such as retries, tracking metrics etc. The actual logic for constructing the query for the operation and then parsing the result set of the operation is left to the implementation of the extending class.
