Usage

Simple use cases will look something like this:

• sample json:

{
  "results": {
    "sample": {
      "a": true,
      "b": [[1,2,3], [4,5,6]],
      "c": {
        "d": [{ "foo":1, "bar":3}, { "foo":2, "bar":1 }]
      }
    }
  }
}

• java class correspond to json

@GSelect("results sample")
public class SampleObject {
    @GSelect("a")
    boolean a; // -> true
    
    @GSelect("b")
    List<int[]> b; // -> [[1,2,3], [4,5,6]]
    
    @GSelect("c d")
    List<Map<String, Integer>> d; // -> [{ "foo":1, "bar":3 }, { "foo":2, "bar":1 }]

    @GSelect("c d foo")
    List<Integer> foo; // -> [1, 2]
}

• get java object from json

String json = ...;
SampleObject sample = new GQuery().select(json, SampleObject.class);
boolean a = new GQuery().get(json, "results sample a", String.class); // -> true

You can see more sample in test code.
