Examples of runScriptlet()

org.jruby.embed.IsolatedScriptingContainer.runScriptlet()
org.jruby.embed.ScriptingContainer.runScriptlet()
Evaluates a script under the current scope (perhaps the top-level scope) and returns a result only if a script returns a value. Right after the parsing, the script is evaluated once. @param script is a Ruby script to get run @return an evaluated result converted to a Java object

Examples of org.jruby.embed.ScriptingContainer.runScriptlet()

        String[] weather = (String[]) container.remove("@weather");
        assertArrayEquals(expResult, weather);
        assertTrue(instance.size() == 4);
        
        // transient local variable should vanish after eval
        container.runScriptlet("a = 1");

        container = new ScriptingContainer(LocalContextScope.SINGLETHREAD, LocalVariableBehavior.PERSISTENT);
        instance = container.getVarMap();
