Example 1 with LiteralExpression

use of org.springframework.expression.common.LiteralExpression in project spring-framework by spring-projects.

the class LiteralExpressionTests method testSetValue.

@Test
public void testSetValue() {
    try {
        LiteralExpression lEx = new LiteralExpression("somevalue");
        lEx.setValue(new StandardEvaluationContext(), "flibble");
        fail("Should have got an exception that the value cannot be set");
    } catch (EvaluationException ee) {
        // success, not allowed - whilst here, check the expression value in the exception
        assertEquals(ee.getExpressionString(), "somevalue");
    }
    try {
        LiteralExpression lEx = new LiteralExpression("somevalue");
        lEx.setValue(new Rooty(), "flibble");
        fail("Should have got an exception that the value cannot be set");
    } catch (EvaluationException ee) {
        // success, not allowed - whilst here, check the expression value in the exception
        assertEquals(ee.getExpressionString(), "somevalue");
    }
    try {
        LiteralExpression lEx = new LiteralExpression("somevalue");
        lEx.setValue(new StandardEvaluationContext(), new Rooty(), "flibble");
        fail("Should have got an exception that the value cannot be set");
    } catch (EvaluationException ee) {
        // success, not allowed - whilst here, check the expression value in the exception
        assertEquals(ee.getExpressionString(), "somevalue");
    }
}

Example 2 with LiteralExpression

use of org.springframework.expression.common.LiteralExpression in project spring-framework by spring-projects.

    LiteralExpression lEx = new LiteralExpression("somevalue");
    assertEquals(String.class, lEx.getValueType());
    assertEquals(String.class, lEx.getValueType(new StandardEvaluationContext()));
    assertEquals(String.class, lEx.getValueType(new Rooty()));
