Return list or nested object as mapped result

[bastiaan-dev]

A bit related to #264 (@bsbodden thx for the fix, tested the changes and both #264 and #265 seem to work)

Not sure if this is a bug or feature request. But instead of returning/mapping every property within a list or nested property, I would like to return the complete list/nested object.

this would then correspond with calling Redis from cli by:

"FT.SEARCH" "nl.domain.myIndex" "LIMIT" "0" "10000" "RETURN" "1" "$.nestedObject" "DIALECT" "1"

instead of:

"FT.SEARCH" "nl.domain.myIndex" "LIMIT" "0" "10000" "RETURN" "2" "$.nestedObject.property1" "$.nestedObject.property2" "DIALECT" "1"

Some (not functioning tests to demonstrate the idea):

@Test
  void testMapEntityStreamsReturnCompleteNestedList() {
    var results = entityStream.of(DeepList.class)
            .filter(DeepList$.NEST_LEVELS.NAME.eq("nl-2-2"))
            .map(DeepList$.NEST_LEVELS) // would like to map complete list of objects instead of each property withing nested list object 
            .collect(Collectors.toList());

    // expecting results.get(0) being instance of List<NestLevel2>
  }

  @Test
  void testMapEntityStreamsReturnCompleteNestedObject() {
    var results = entityStream.of(DeepNest.class)
            .filter(DeepNest$.NEST_LEVEL1_NEST_LEVEL2_NAME.eq("nl-2-2"))
            .map(DeepNest$.NEST_LEVEL1) // would like to map complete object instead of each property seperately
            .collect(Collectors.toList());

    // expecting results.get(0) being instance of NestLevel1
  }
