Class VoltCompoundProcedure.StageListBuilder

java.lang.Object

org.voltdb.VoltCompoundProcedure.StageListBuilder

Enclosing class:

VoltCompoundProcedure

public final class VoltCompoundProcedure.StageListBuilder
extends java.lang.Object

Builds a list of execution stages for this VoltCompoundProcedure.

The stage list is built at the start of execution, in your procedure's run method, like this:

newStageList(STAGE)
    .then(STAGE)
    .then(STAGE)
    .build();
 

A stage list is created by the call to VoltCompoundProcedure.newStageList(java.util.function.Consumer<org.voltdb.client.ClientResponse[]>), with the first stage to be executed. Additional stages can be added one-by-one as required by the application logic. Once built, the stage list cannot be changed.
