Example 41 with ValueExpression

use of jakarta.el.ValueExpression in project tomcat by apache.

the class TestELParser method doTestParser.

private void doTestParser(String input, String expectedResult, String expectedBuilderOutput) throws JasperException {
    ELException elException = null;
    String elResult = null;
    // Don't try and evaluate expressions that depend on variables or functions
    if (expectedResult != null) {

            ELManager manager = new ELManager();
            ELContext context = manager.getELContext();
            ExpressionFactory factory = ELManager.getExpressionFactory();
            ValueExpression ve = factory.createValueExpression(context, input, String.class);
            elResult = ve.getValue(context).toString();
            Assert.assertEquals(expectedResult, elResult);
        } catch (ELException ele) {
            elException = ele;

        Assert.assertNull(elException);
    } catch (IllegalArgumentException iae) {
        Assert.assertNotNull(elResult, elException);
        // Not strictly true but enables us to report both

Example 42 with ValueExpression

use of jakarta.el.ValueExpression in project tomcat by apache.

the class TestAttributeParser method evalAttr.

    ELContextImpl ctx = new ELContextImpl(exprFactory);
    ctx.setFunctionMapper(new TesterFunctions.FMapper());
