manifold.sql.rt.impl

Class ResourceDbLocationProvider

java.lang.Object

manifold.sql.rt.impl.ResourceDbLocationProvider

All Implemented Interfaces:

DbLocationProvider

public class ResourceDbLocationProvider
extends java.lang.Object
implements DbLocationProvider

DbLocationProvider for: #resource and #resource_script. This functionality is primarily aimed at testing to support a fresh database file for embeddable databases such as H2, Sqlite, etc.

Handle expression syntax like: ${#resource /org/example/MyDatabase.db [, MyName][, args]}

Where /org/example/MyDatabase.db is an absolute Java resource path to a sql database file and the optional MyName parameter is the file name to be used for the resulting URL path string (if different from the file name), and args can be additional options such as ";create=true;blah=blah". Alternatively, additional options can usually be provided as DbConfig properties.

Copies the contents of /org/example/MyDatabase.db to a temp directory and returns the temp dir path, and if specified, replaces MyDatabase.db file name with MyName.

Also handles ${#resource_script ... } with same functionality as #resource, but the resource path is a DDL script instead of a database file. Here, MyName must be provided as the resulting URL db file name. The DDL file is executed when the first connection is made to the db.
