Example 1 with PV

use of org.csstudio.vtype.pv.PV in project org.csstudio.display.builder by kasemir.

the class RulesJythonScriptTest method testJythonScript.

@Test
public void testJythonScript() throws Exception {

    System.out.println(widget);
    String pv_name = "loc://test2";
    PVPool.addPVFactory(new LocalPVFactory());
    final PV pv = PVPool.getPV(pv_name);
