Examples with MethodExpression javax.el.MethodExpression used on opensource projects

Example 1 with MethodExpression

use of javax.el.MethodExpression in project tomcat by apache.

the class AstIdentifier method getMethodExpression.

private final MethodExpression getMethodExpression(EvaluationContext ctx) throws ELException {
    Object obj = null;
    // case A: ValueExpression exists, getValue which must
    // be a MethodExpression
    VariableMapper varMapper = ctx.getVariableMapper();
    ValueExpression ve = null;
    if (varMapper != null) {
        ve = varMapper.resolveVariable(this.image);
        if (ve != null) {
            obj = ve.getValue(ctx);
        }
    }
    // a MethodExpression to be able to invoke
    if (ve == null) {
        ctx.setPropertyResolved(false);
        obj = ctx.getELResolver().getValue(ctx, null, this.image);
    }
    // finally provide helpful hints
    if (obj instanceof MethodExpression) {
        return (MethodExpression) obj;
    } else if (obj == null) {
        throw new MethodNotFoundException("Identity '" + this.image + "' was null and was unable to invoke");
    } else {
        throw new ELException("Identity '" + this.image + "' does not reference a MethodExpression instance, returned type: " + obj.getClass().getName());
    }
}

Example 2 with MethodExpression

use of javax.el.MethodExpression in project tomcat by apache.

the class TestMethodExpressionImpl method testBug57855b.

@Test(expected = IllegalArgumentException.class)
public void testBug57855b() {
    MethodExpression me = factory.createMethodExpression(context, "${beanAA.echo2}", null, new Class[] { String.class });
    me.invoke(context, null);
}

Example 3 with MethodExpression

use of javax.el.MethodExpression in project tomcat by apache.

the class TestMethodExpressionImpl method testInvokeWithVarArgsAAAB.

@Test
public void testInvokeWithVarArgsAAAB() throws Exception {
    MethodExpression me7 = factory.createMethodExpression(context, "${beanC.sayHello(beanAAA,beanB,beanB)}", null, null);
    Exception e = null;
    try {
        me7.invoke(context, null);
    } catch (Exception e1) {
        e = e1;
    }
    // Expected to fail
    assertNotNull(e);
}

@Test
public void testBug52970() {
    MethodExpression me = factory.createMethodExpression(context, "${beanEnum.submit('APPLE')}", null, new Class<?>[] { TesterBeanEnum.class });
    me.invoke(context, null);
    ValueExpression ve = factory.createValueExpression(context, "#{beanEnum.lastSubmitted}", TesterEnum.class);
    TesterEnum actual = (TesterEnum) ve.getValue(context);
    assertEquals(TesterEnum.APPLE, actual);
}

use of javax.el.MethodExpression in project tomcat by apache.

the class TestMethodExpressionImpl method testInvokeWithVarArgsAAABBB.

@Test
public void testInvokeWithVarArgsAAABBB() throws Exception {
    MethodExpression me9 = factory.createMethodExpression(context, "${beanC.sayHello(beanAAA,beanBBB,beanBBB)}", null, null);
    Object r9 = me9.invoke(context, null);
    assertEquals("ABB[]: Hello AAA from BBB, BBB", r9.toString());
