Examples with E_Multiply org.apache.jena.sparql.expr.E_Multiply used on opensource projects

Example 1 with E_Multiply

use of org.apache.jena.sparql.expr.E_Multiply in project jena by apache.

the class TestUserDefinedFunctionFactory method test_user_defined_function_factory_add_03.

@Test
public void test_user_defined_function_factory_add_03() throws ParseException {
    Expr e = new E_Multiply(new ExprVar("x"), new ExprVar("x"));
    //Instead of registering the pre-built expression register using a string for the expression
    UserDefinedFunctionFactory.getFactory().add("http://example/square", "?x * ?x", new ArrayList<>(e.getVarsMentioned()));
    Assert.assertTrue(UserDefinedFunctionFactory.getFactory().isRegistered("http://example/square"));
    Assert.assertEquals(e, UserDefinedFunctionFactory.getFactory().get("http://example/square").getBaseExpr());
}
