Function Documentation

FLDoc_FromJSON()

FLEECE_PUBLIC FLDoc FLDoc_FromJSON	(	FLSlice	json,
		FLError *FL_NULLABLE	outError
	)

Creates an FLDoc from JSON-encoded data.

The data is first encoded into Fleece, and the Fleece data is kept by the doc; the input JSON data is no longer needed after this function returns.

FLEncoder_ConvertJSON()

FLEECE_PUBLIC bool FLEncoder_ConvertJSON	(	FLEncoder	,
		FLSlice	json
	)

Parses JSON data and writes the value(s) to the encoder as their Fleece equivalents.

(This acts as a single write, like WriteInt; it's just that the value written is likely to be an entire dictionary or array.)

FLMutableArray_NewFromJSON()

FLEECE_PUBLIC FLMutableArray FL_NULLABLE FLMutableArray_NewFromJSON	(	FLString	json,
		FLError *FL_NULLABLE	outError
	)

Creates a new mutable Array from JSON.

It is an error if the JSON is not an array. Its initial ref-count is 1, so a call to FLMutableArray_Release will free it.

FLMutableDict_NewFromJSON()

FLEECE_PUBLIC FLMutableDict FL_NULLABLE FLMutableDict_NewFromJSON	(	FLString	json,
		FLError *FL_NULLABLE	outError
	)

Creates a new mutable Dict from json.

It is an error if the JSON is not a dictionary/object. Its initial ref-count is 1, so a call to FLMutableDict_Release will free it.

FLValue_ToJSON()

FLEECE_PUBLIC FLStringResult FLValue_ToJSON

(

FLValue

FL_NULLABLE

)

Encodes a Fleece value as JSON (or a JSON fragment.)

Note

Any Data values will be encoded as base64-encoded strings.

FLValue_ToJSON5()

FLEECE_PUBLIC FLStringResult FLValue_ToJSON5

(

FLValue

FL_NULLABLE

)

Encodes a Fleece value as JSON5, a more lenient variant of JSON that allows dictionary keys to be unquoted if they're alphanumeric.

This tends to be more readable.

Note

Any Data values will be encoded as base64-encoded strings.

FLValue_ToJSONX()

FLEECE_PUBLIC FLStringResult FLValue_ToJSONX	(	FLValue FL_NULLABLE	v,
		bool	json5,
		bool	canonicalForm
	)

Most general Fleece to JSON converter.

Parameters

v	The Fleece value to encode
json5	If true, outputs JSON5, like FLValue_ToJSON5
canonicalForm	If true, outputs the JSON in a consistent "canonical" form. All equivalent values should produce byte-for-byte identical canonical JSON. This is useful for creating digital signatures, for example.
