Method Details

createJrt

protected JRT createJrt()

Description copied from class: AVM

Creates the runtime this interpreter drives.

Called once from the constructor, so that a subclass can install its own runtime — SandboxedAVM returns a SandboxedJRT this way. It runs before the subclass constructor body, so an override must not depend on the subclass's own fields.

Overrides:

createJrt in class AVM

Returns:

the runtime bound to this interpreter, never null
