Example 1 with EqualityExpression

use of org.graylog.plugins.pipelineprocessor.ast.expressions.EqualityExpression in project graylog2-server by Graylog2.

the class PrecedenceTest method comparisonVsEqual.

@Test
public void comparisonVsEqual() {
    final Rule rule = parseRule("rule \"test\" when 1 > 2 == false then end");
    final LogicalExpression when = rule.when();
    assertThat(when).isInstanceOf(EqualityExpression.class);
    EqualityExpression topEqual = (EqualityExpression) when;
    assertThat(topEqual.left()).isInstanceOf(ComparisonExpression.class);
    assertThat(topEqual.right()).isInstanceOf(BooleanExpression.class);
}

Example 2 with EqualityExpression

use of org.graylog.plugins.pipelineprocessor.ast.expressions.EqualityExpression in project graylog2-server by Graylog2.

the class PrecedenceTest method parenGroup.

@Test
public void parenGroup() {
    final Rule rule = parseRule("rule \"test\" when true == (false == false) then end");
    final LogicalExpression when = rule.when();
    assertThat(when).isInstanceOf(EqualityExpression.class);
    EqualityExpression topEqual = (EqualityExpression) when;
    assertThat(topEqual.left()).isInstanceOf(BooleanExpression.class);

    final BooleanExpression trueExpr = (BooleanExpression) topEqual.left();
    assertThat(trueExpr.evaluateBool(null)).isTrue();
    final EqualityExpression falseFalse = (EqualityExpression) topEqual.right();
    assertThat(falseFalse.evaluateBool(null)).isTrue();
