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

Example 26 with ELProcessor

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

the class TestCollectionOperations method testForEach01.

@Test
public void testForEach01() {
    ELProcessor processor = new ELProcessor();
    processor.defineBean("beans", beans);
    processor.getValue("beans.stream().forEach(b->b.setValLong(b.valLong + 1))", Object.class);
    Assert.assertEquals(2, bean01.getValLong());
    Assert.assertEquals(3, bean02.getValLong());
    Assert.assertEquals(4, bean03.getValLong());
    // Restore the beans to their default state
    processor.getValue("beans.stream().forEach(b->b.setValLong(b.valLong - 1))", Object.class);
    Assert.assertEquals(1, bean01.getValLong());
    Assert.assertEquals(2, bean02.getValLong());
    Assert.assertEquals(3, bean03.getValLong());
}
