Outside() API can not process boolean value

Bug Type (问题类型)

gremlin (结果不合预期)

Before submit

• [X] 我已经确认现有的 Issues 与 FAQ 中没有相同 / 重复问题

Environment (环境信息)

• Server Version: v0.11.2
• Backend: Memory
• OS: 16 CPUs, 64 G RAM, windows10 WSL
• Data Size: 200 vertices, 100 edges

Expected & Actual behavior (期望与实际表现)

Expected behavior

We executed the query “ g.V().has('person', 'married', outside(true, true))”, and expected to get the vertices whose property ‘married’ was FALSE.

Actual behavior

An exception was thrown:

java.lang.NumberFormatException: Error encountered evaluating script: g.V().has('person', 'married', outside(true, true))

Caused by: [java.lang.NumberFormatException]

Example to reproduce

        hugegraph.schema().propertyKey("married").asBoolean().ifNotExist().create();

        hugegraph.schema().vertexLabel("person").properties("married").nullableKeys("married").create();
        hugegraph.schema().indexLabel("personbymarried").onV("person").by("married").shard().ifNotExist().create();

        GraphManager graph = hugegraph.graph();

        Vertex person1 = new Vertex("person").property("married", true);
        Vertex person2 = new Vertex("person").property("married", false);
        Vertex person3 = new Vertex("person").property("married", false);
        Vertex person4 = new Vertex("person").property("married", false);

        graph.addVertices(Arrays.asList(person1, person2, person3, person4));

        GremlinManager gremlin = hugegraph.gremlin();

        String query0 = "g.V().has('person', 'married', outside(true, true))";
        System.out.println("query0 : " + query0);
        try{
            ResultSet hugeResult = gremlin.gremlin(query0).execute();
            Iterator<Result> huresult = hugeResult.iterator();
            huresult.forEachRemaining(result -> {
                Object object = result.getObject();
                System.out.println(object);
            });
        }catch(Exception e){
            e.printStackTrace();
        }

The code and query of same logic will not cause exception in other gremlin-based graph databases.

@imbajin Could you please check whether this bug is related to HugeGraph? Thanks a lot~

[imbajin]

I'm not sure, assign other devs to check ⏲️

@Yicheng-Wang The outside() syntax only supports numeric properties, within() or without() syntax supports boolean properties.
