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

Example 26 with ValueExpression

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

the class TestAstAssign method testGetType02.

@Test
public void testGetType02() {
    ELProcessor processor = new ELProcessor();
    ELContext context = processor.getELManager().getELContext();
    ExpressionFactory factory = ELManager.getExpressionFactory();
    processor.defineBean("bean01", new TesterBeanB());
    ValueExpression ve = factory.createValueExpression(context, "${bean01.text = 'hello'; bean01.text}", String.class);
    Assert.assertEquals(String.class, ve.getType(context));
    Assert.assertEquals("hello", ve.getValue(context));
}

Example 27 with ValueExpression

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

the class TestAstConcatenation method testGetType.

@Test
public void testGetType() {
    ELProcessor processor = new ELProcessor();
    ELContext context = processor.getELManager().getELContext();
    ExpressionFactory factory = ELManager.getExpressionFactory();
    ValueExpression ve = factory.createValueExpression(context, "${'a' += 3}", String.class);
    Assert.assertEquals(String.class, ve.getType(context));
    Assert.assertEquals("a3", ve.getValue(context));
}

Example 28 with ValueExpression

use of javax.el.ValueExpression in project jersey by jersey.

the class LinkELContextTest method testLiteralExpression.

@Test
public void testLiteralExpression() {
    System.out.println("Literal expression");
    ExpressionFactory factory = ExpressionFactory.newInstance();
    LinkELContext context = new LinkELContext(new BooleanBean(), null);
    ValueExpression expr = factory.createValueExpression(context, "${1+2}", int.class);
    Object value = expr.getValue(context);
    assertEquals(3, value);
}

Example 29 with ValueExpression

use of javax.el.ValueExpression in project jersey by jersey.

the class LinkELContextTest method testBooleanExpression.

@Test
public void testBooleanExpression() {
    System.out.println("Boolean expression");
    ExpressionFactory factory = ExpressionFactory.newInstance();
    LinkELContext context = new LinkELContext(new BooleanBean(), null);
    ValueExpression expr = factory.createValueExpression(context, "${entity.enabled}", boolean.class);
    Object value = expr.getValue(context);
    assertEquals(true, value);
    expr = factory.createValueExpression(context, "${entity.getValue(true)}", boolean.class);
    value = expr.getValue(context);
    assertEquals(true, value);
    expr = factory.createValueExpression(context, "${entity.getValue(false)}", boolean.class);
    value = expr.getValue(context);
    assertEquals(false, value);
}

Example 30 with ValueExpression

use of javax.el.ValueExpression in project jersey by jersey.

the class LinkELContextTest method testExpression.

@Test
public void testExpression() {
    System.out.println("Raw expression");
    ExpressionFactory factory = ExpressionFactory.newInstance();
    LinkELContext context = new LinkELContext(new EntityBean(), null);
    ValueExpression expr = factory.createValueExpression(context, "${entity.id}", String.class);
    Object value = expr.getValue(context);
    assertEquals(ID, value);
