- org.apache.brooklyn.util.collections.Jsonya

```
public class Jsonya
extends java.lang.Object
```
Jsonya = JSON-yet-another (tool)
provides conveniences for working with maps and lists containing maps and lists, and other datatypes too, easily convertible to json.
see JsonyaTest for examples

Nested Class Summary

Nested Classes
Modifier and Type	Class and Description
`static class`	`Jsonya.JsonPrimitiveDeepTranslator` Converts an object to one which uses standard JSON objects where possible (strings, numbers, booleans, maps, lists), and uses toString elsewhere
`static class`	`Jsonya.Navigator<T extends java.util.Map<?,?>>`

Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method and Description
`static Jsonya.Navigator<MutableMap<java.lang.Object,java.lang.Object>>`	`at(java.lang.Object... pathSegments)` convenience for `Jsonya.Navigator.at(Object, Object...)` on a `newInstance()`
`static java.lang.Object`	`convertToJsonPrimitive(java.lang.Object x)` convenience for converting an object x to something which consists only of json primitives, doing `Object.toString()` on anything which is not recognised.
`static boolean`	`isJsonPrimitiveCompatible(java.lang.Object x)` tells whether `convertToJsonPrimitive(Object)` returns an object which is identical to the equivalent literal json structure.
`static Jsonya.Navigator<MutableMap<java.lang.Object,java.lang.Object>>`	`newInstance()` creates a `Jsonya.Navigator` backed by a newly created map; the map can be accessed by `Navigator#getMap()`
`static Jsonya.Navigator<MutableMap<java.lang.Object,java.lang.Object>>`	`newInstanceLiteral()` as `#newInstanceTranslating(Function)` using an identity function (functionally equivalent to `newInstance()` but explicit about it
`static Jsonya.Navigator<MutableMap<java.lang.Object,java.lang.Object>>`	`newInstancePrimitive()` as `#newInstanceTranslating(Function)` using a function which only supports JSON primitives: maps and collections are traversed, strings and primitives are inserted, and everything else has toString applied.
`static Jsonya.Navigator<MutableMap<java.lang.Object,java.lang.Object>>`	`newInstanceTranslating(<any> translator)` as `newInstance()` but using the given translator to massage objects inserted into the Jsonya structure
`static <T extends java.util.Map<?,?>> Jsonya.Navigator<T>`	`of(Jsonya.Navigator<T> navigator)` creates a `Jsonya.Navigator` backed by the map at the focus of the given navigator
`static <T extends java.util.Map<?,?>> Jsonya.Navigator<T>`	`of(T map)` creates a `Jsonya.Navigator` backed by the given map (focussed at the root)
`static java.lang.String`	`render(java.lang.Object focus)`

    as #newInstanceTranslating(Function) using a function which only supports JSON primitives: maps and collections are traversed, strings and primitives are inserted, and everything else has toString applied. see Jsonya.JsonPrimitiveDeepTranslator
  - convertToJsonPrimitive
```
public static java.lang.Object convertToJsonPrimitive(java.lang.Object x)
```
    convenience for converting an object x to something which consists only of json primitives, doing Object.toString() on anything which is not recognised. see Jsonya.JsonPrimitiveDeepTranslator
  - isJsonPrimitiveCompatible
```
public static boolean isJsonPrimitiveCompatible(java.lang.Object x)
```
    tells whether convertToJsonPrimitive(Object) returns an object which is identical to the equivalent literal json structure. this is typically equivalent to saying serializing to json then deserializing will produce something where the result is equal to the input, modulo a few edge cases such as longs becoming ints. note that the converse (input equal to output) may not be the case, e.g. if the input contains special subclasses of collections of maps who care about type preservation.
