Examples with ExpressionCache com.dexels.navajo.parser.compiled.api.ExpressionCache used on opensource projects

Example 1 with ExpressionCache

use of com.dexels.navajo.parser.compiled.api.ExpressionCache in project navajo by Dexels.

the class TestCompiledExpression method testFunctionType.

@Test
public void testFunctionType() {
    ExpressionCache ce = ExpressionCache.getInstance();
    List<String> problems = new ArrayList<>();
    ContextExpression cx = ce.parse(problems, "ToUpper([whatever])", name -> FunctionClassification.DEFAULT);
    Assert.assertEquals(Property.STRING_PROPERTY, cx.returnType().get());
}

Example 2 with ExpressionCache

use of com.dexels.navajo.parser.compiled.api.ExpressionCache in project navajo by Dexels.

the class TestTypeCheckCompiledExpressionEvaluator method testEquals.

@Test
public void testEquals() {
    ExpressionCache ce = ExpressionCache.getInstance();
    List<String> problems = new ArrayList<>();
    ContextExpression cx = ce.parse(problems, "1==1", fn -> FunctionClassification.DEFAULT);

Example 3 with ExpressionCache

use of com.dexels.navajo.parser.compiled.api.ExpressionCache in project navajo by Dexels.

the class TestTypeCheckCompiledExpressionEvaluator method testUnknown.

@Test
public void testUnknown() {
    // test unknowable type
    ExpressionCache ce = ExpressionCache.getInstance();
    List<String> problems = new ArrayList<>();
    ContextExpression cx = ce.parse(problems, "[bla]", fn -> FunctionClassification.DEFAULT);
    Assert.assertFalse(cx.returnType().isPresent());

Example 4 with ExpressionCache

use of com.dexels.navajo.parser.compiled.api.ExpressionCache in project navajo by Dexels.

the class TestTypeCheckCompiledExpressionEvaluator method testBadType.

@Test
public void testBadType() {
    // test unknowable type
    ExpressionCache ce = ExpressionCache.getInstance();
    List<String> problems = new ArrayList<>();
    // the [] expression has been added to prevent the expression to be pre-evaluated (as all other params are literals
    ContextExpression cx = ce.parse(problems, "1 AND 'monkey' AND [whoop]", fn -> FunctionClassification.DEFAULT);
    System.err.println("Problems: " + problems);
    Assert.assertEquals(2, problems.size());
