Examples with MethodInfo jakarta.el.MethodInfo used on opensource projects

Example 1 with MethodInfo

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

the class TestMethodExpressionImpl method testGetMethodInfo02.

@Test
public void testGetMethodInfo02() throws Exception {
    MethodExpression me = factory.createMethodExpression(context, "#{beanA.setName}", null, new Class[] { String.class });
    // This is the call that failed
    MethodInfo mi = me.getMethodInfo(context);
    // The rest is to check it worked correctly
    Assert.assertEquals(void.class, mi.getReturnType());
    Assert.assertEquals(1, mi.getParamTypes().length);
    Assert.assertEquals(String.class, mi.getParamTypes()[0]);
}

Example 2 with MethodInfo

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

the class TestMethodExpressionImpl method testGetMethodInfo01.

@Test
public void testGetMethodInfo01() throws Exception {
    MethodExpression me = factory.createMethodExpression(context, "#{beanA.setName('New value')}", null, null);
    // This is the call that failed
    MethodInfo mi = me.getMethodInfo(context);
    // The rest is to check it worked correctly
    Assert.assertEquals(void.class, mi.getReturnType());
    Assert.assertEquals(1, mi.getParamTypes().length);
    Assert.assertEquals(String.class, mi.getParamTypes()[0]);
}

Example 3 with MethodInfo

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

the class MethodExpressionLiteral method getMethodInfo.

@Override
public MethodInfo getMethodInfo(ELContext context) throws ELException {
    context.notifyBeforeEvaluation(getExpressionString());
    MethodInfo result = getMethodInfoInternal();
    context.notifyAfterEvaluation(getExpressionString());
    return result;
}

Example 4 with MethodInfo

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

the class MethodExpressionImpl method getMethodInfo.

/**
 * Evaluates the expression relative to the provided context, and returns
 * information about the actual referenced method.
 *
 * @param context
 *            The context of this evaluation
 * @return an instance of <code>MethodInfo</code> containing information
 *         about the method the expression evaluated to.
 * @throws NullPointerException
 *             if context is <code>null</code> or the base object is
 *             <code>null</code> on the last resolution.
 * @throws PropertyNotFoundException
 *             if one of the property resolutions failed because a specified
 *             variable or property does not exist or is not readable.
 * @throws MethodNotFoundException
 *             if no suitable method can be found.
 * @throws ELException
 *             if an exception was thrown while performing property or
 *             variable resolution. The thrown exception must be included as
 *             the cause property of this exception, if available.
 * @see jakarta.el.MethodExpression#getMethodInfo(jakarta.el.ELContext)

@Override

    EvaluationContext ctx = new EvaluationContext(context, this.fnMapper, this.varMapper);
    ctx.notifyBeforeEvaluation(getExpressionString());
    MethodInfo result = n.getMethodInfo(ctx, this.paramTypes);
    ctx.notifyAfterEvaluation(getExpressionString());
    return result;
}

Example 5 with MethodInfo

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

the class AstValue method getMethodInfo.

@Override
public // Interface el.parser.Node uses raw types (and is auto-generated)
MethodInfo getMethodInfo(EvaluationContext ctx, @SuppressWarnings("rawtypes") Class[] paramTypes) throws ELException {
    Target t = getTarget(ctx);
    Class<?>[] types = null;

    } else {
        types = paramTypes;
    }
    Method m = ReflectionUtil.getMethod(ctx, t.base, t.property, types, null);
    return new MethodInfo(m.getName(), m.getReturnType(), m.getParameterTypes());
