const mixinafJson::JsonConverters

The default set of JSON <-> Fantom converters.

Converts a JSON string to the given Fantom type.

Returns null if json is null.

Converts a list of JSON values to the given Fantom (non-list) type.

fromJsonList(list, MyEntity#)

Convenience for calling fromJsonVal() with a cast.

Converts a JSON object to the given Fantom type.

Convenience for calling fromJsonVal() with a cast.

If fantomType is null then the obj is inspected for a _type property.

Converts a JSON value to the given Fantom type.

If fantomType is null then the obj is inspected for a _type property, else a reasonable guess is made (and the option docToTypeFn is then called as a last resort.)

jsonVal is nullable so converters can choose whether or not to create empty lists and maps.

Returns the Converter instance used to convert the given type.

Returns a new JsonConverters instance.

If converters is null then defConvs is used. Some defaults are:

makeEntityFn      : |Type type, Field:Obj? fieldVals->Obj?| { BeanBuilder.build(type, vals) }
makeJsonObjFn     : |-> Str:Obj?| { Str:Obj?[:] { ordered = true } }
fromJsonHookFn    : |Obj? obj, JsonConverterCtx->Obj?| { obj }
toJsonHookFn      : |Obj? obj, JsonConverterCtx->Obj?| { obj } 
dateFormat        : "YYYY-MM-DD"
dateTimeFormat    : "YYYY-MM-DD'T'hh:mm:ss.FFFz"
strictMode        : false
propertyCache     : JsonPropertyCache()
pickleMode        : false
doNotWriteNulls   : false
encodeDecodeUris  : true - set to false to use Uri.toStr / Str.toUri

Override makeEntityFn to have IoC create entity instances.

Hook fns are called before conversion takes place.

Date formats are used to serialise Date and Time objects.

Set strictMode to true to Err if the JSON contains unmapped data.

Pickle Mode is where all non @Transient fields are converted, regardless of any @JsonProperty facets. Data from @JsonProperty facets, however, is still honoured if defined.

Returns a fn that normalises .NET and snake_case key names into standard Fantom camelCase names.

.NET examples
-------------
UniqueID        -->  uniqueId
SWVersion       -->  swVersion
MegaVERIndex    -->  megaVerIndex
UtilITEMS.Rec   -->  utilItems.rec

Snake_case examples
-------------------
unique_id       -->  uniqueId
sw_Version      -->  swVersion
mega_VER_Index  -->  megaVerIndex

Use as a hook option:

converters := JsonConverters(null, [
    "fromJsonHook" : JsonConverters.normaliseKeyNamesFn
])

Converts the given Fantom object to its JSON string representation.

options is passed to JsonWriter, so may just be true for pretty printing.

Deeply converts the given Fantom List to its JSON representation.

Convenience for calling toJsonVal() with a cast.

Converts the given Fantom object to its JSON object representation.

Convenience for calling toJsonVal() with a cast.

Converts the given Fantom object to its JSON representation.

fantomObj is nullable so converters can create empty / default objects. fantomType in case fantomObj is null, but defaults to fantomObj?.typeof.

Returns a new JsonConverters whose options are overridden with the given ones.
