Nested classes can be static or non-static "inner" classes. Inner classes can access fields in the outer class - a feature not demonstrated here.

TODO: Test that use case here.

Method Detail

doInside

public void doInside()
              throws SchemaChangeException

Because of how Drill does byte-code merging, the methods on the inner class cannot be abstract; they must have an empty implementation which is discarded and replaced with the generated implementation. In plain-old Java, the generated method overrides this one.

Throws:

SchemaChangeException - all methods that Drill generates throw this exception. This does not matter for byte-code merge, but plain-old Java requires that the overridden method declare any exceptions thrown by the overriding method.

doDouble

public void doDouble()
              throws SchemaChangeException

Not overridden. Must pass along (or handle) the SchemaChangeException thrown by the generated method.

Throws:

SchemaChangeException

newDoubleInner

protected ExampleTemplateWithInner.TheInnerClass.DoubleInner newDoubleInner()

injectMembers

protected ExampleTemplateWithInner.TheInnerClass.DoubleInner injectMembers(ExampleTemplateWithInner.TheInnerClass.DoubleInner doubleInner)
