Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`Iterable<String>`	`discoverRootFields(T obj)`	List all "root" fields.
`default Object`	`finalizeConversionForMap(Object o)`	Handle any special conversions for object when translating an input type into a `Map` for `toMap(T)`
`com.jayway.jsonpath.spi.json.JsonProvider`	`getJsonProvider()`
`Object`	`getRootField(T obj, String key)`	Get a top level field from a "json" object
`Function<T,Object>`	`makeJsonPathExtractor(String expr)`	Create a "field" extractor for `JsonPath` expressions
`Function<T,Object>`	`makeJsonQueryExtractor(String expr)`	Create a "field" extractor for 'jq' expressions
`default Function<T,Object>`	`makeJsonTreeExtractor(List<String> nodes)`	Create a "field" extractor for nested json expressions
`default Map<String,Object>`	`toMap(T obj)`	Convert object to Java `Map` using `getJsonProvider()` and `finalizeConversionForMap(java.lang.Object)` to extract and convert data
`default Object`	`toPlainJavaType(Object o)`	Recursively traverse "json" object using a `JsonProvider`, converting to Java `Map` and `List`, potentially transforming via `finalizeConversionForMap(java.lang.Object)` as we go

  - getJsonProvider
```
com.jayway.jsonpath.spi.json.JsonProvider getJsonProvider()
```
  - discoverRootFields
```
Iterable<String> discoverRootFields(T obj)
```
    List all "root" fields. If DimensionsSpec.useSchemaDiscovery is false, this method should filter fields to include only fields that contain primitive and lists of primitive values
  - getRootField
```
Object getRootField(T obj,
                    String key)
```
    Get a top level field from a "json" object
  - makeJsonPathExtractor
```
Function<T,Object> makeJsonPathExtractor(String expr)
```
    Create a "field" extractor for JsonPath expressions
  - makeJsonQueryExtractor
```
Function<T,Object> makeJsonQueryExtractor(String expr)
```
    Create a "field" extractor for 'jq' expressions
  - makeJsonTreeExtractor
```
default Function<T,Object> makeJsonTreeExtractor(List<String> nodes)
```
    Create a "field" extractor for nested json expressions
  - toMap
```
default Map<String,Object> toMap(T obj)
```
    Convert object to Java Map using getJsonProvider() and finalizeConversionForMap(java.lang.Object) to extract and convert data
  - toPlainJavaType
```
@Nullable
default Object toPlainJavaType(Object o)
```
    Recursively traverse "json" object using a JsonProvider, converting to Java Map and List, potentially transforming via finalizeConversionForMap(java.lang.Object) as we go
  - finalizeConversionForMap
```
default Object finalizeConversionForMap(Object o)
```
    Handle any special conversions for object when translating an input type into a Map for toMap(T)
