Constructor Details

SqlStatementFactory

public SqlStatementFactory(SqlToolbox lifecycleToolbox)

The construction of these objects in the production code is a bit circuitous. Specifically, the SqlToolbox looks like it can be normally injected, except it actually expects to be mutated with a SqlEngine before being injected. This is generally accomplished with Guice, examples of which can be seen in the SqlStatementFactoryModule.

Parameters:

lifecycleToolbox -
