Examples with Node org.apache.calcite.linq4j.tree.Node used on opensource projects

Example 1 with Node

use of org.apache.calcite.linq4j.tree.Node in project calcite by apache.

the class ExpressionTest method testWriteTryCatchFinally.

@Test
public void testWriteTryCatchFinally() {
    final ParameterExpression cce_ = Expressions.parameter(Modifier.FINAL, ClassCastException.class, "cce");
    final ParameterExpression re_ = Expressions.parameter(0, RuntimeException.class, "re");

    assertEquals("try {\n" + "  return \"foo\".length();\n" + "} catch (final ClassCastException cce) {\n" + "  return null;\n" + "} catch (RuntimeException re) {\n" + "  throw new IndexOutOfBoundsException();\n" + "} finally {\n" + "  \"foo\".toUpperCase();\n" + "}\n", Expressions.toString(node));
}

Example 2 with Node
