Class PermazenExecutionControl

java.lang.Object

All Implemented Interfaces:

public class PermazenExecutionControl
extends org.dellroad.jct.jshell.LocalContextExecutionControl

Permazen-aware LocalExecutionControl.

When snippets are evaluated, the Permazen Session obtained from PermazenJShellShellSession.getPermazenSession() is used to create a transaction that stays open for the duration of the snippet execution and the subsequent formatting of the returned result. In effect each JShell command executes within its own transaction, and the evaluated expressions may directly access and manipulate database objects.
