Class SqlModule.SqlStatementFactoryModule

java.lang.Object

org.apache.druid.sql.guice.SqlModule.SqlStatementFactoryModule

All Implemented Interfaces:

com.google.inject.Module

Enclosing class:

SqlModule

public static class SqlModule.SqlStatementFactoryModule
extends Object
implements com.google.inject.Module

We create a new class for this module so that it can be shared by tests. The structuring of the SqlModule at time of writing was not conducive to reuse in test code, so, instead of fixing that we just take the easy way out of adding the test-reusable code to this module and reuse that. Generally speaking, the injection pattern done by this module is a bit circuitous. The `SqlToolbox` acts as if it can be injected with all of its dependencies, but also expects to be mutated with a new SqlEngine. We should likely look at adjusting the object dependencies to actually depend on the SqlToolbox and create different Toolboxes for the different way that queries are done. But, for now, I'm not changing the interfaces.
