## Description

JsonGenerator provides an object for generating a JSON data stream and put it into a buffer or a file.

## Details

### JsonGenerator

    typedef struct _JsonGenerator JsonGenerator;

JSON data streams generator. The contents of the JsonGenerator structure are private and should only be accessed via the provided API.

### JsonGeneratorClass

    typedef struct {
    } JsonGeneratorClass;

JsonGenerator class

### json_generator_new ()

    JsonGenerator *     json_generator_new                  (void);

Creates a new JsonGenerator. You can use this object to generate a JSON data stream starting from a data object model composed by JsonNodes.

Returns : | the newly created JsonGenerator instance

### json_generator_to_file ()

    gboolean            json_generator_to_file              (JsonGenerator *generator,
                                                             const gchar *filename,
                                                             GError **error);

Creates a JSON data stream and puts it inside `filename`, overwriting the current file contents. This operation is atomic.

`generator` : | a JsonGenerator
`filename` : | path to the target file
`error` : | return location for a GError, or `NULL`
Returns : | `TRUE` if saving was successful.

### json_generator_to_data ()

    gchar *             json_generator_to_data              (JsonGenerator *generator,
                                                             gsize *length);

Generates a JSON data stream from `generator` and returns it as a buffer.

`generator` : | a JsonGenerator
`length` : | out. out.
Returns : | a newly allocated buffer holding a JSON data stream. Use `g_free()` to free the allocated resources.

### json_generator_set_root ()

    void                json_generator_set_root             (JsonGenerator *generator,
                                                             JsonNode *node);

Sets `node` as the root of the JSON data stream to be serialized by the JsonGenerator.

### Note

The node is copied by the generator object, so it can be safely freed after calling this function.

`generator` : | a JsonGenerator
`node` : | a JsonNode

## Property Details

### The `"indent"` property

      "indent"                   guint                 : Read / Write

Number of spaces to be used to indent when pretty printing.

Default value: 2

### The `"indent-char"` property

      "indent-char"              guint                 : Read / Write

The character that should be used when indenting in pretty print.

Default value: ' '

Since 0.6

### The `"pretty"` property

      "pretty"                   gboolean              : Read / Write

Whether the output should be "pretty-printed", with indentation and newlines. The indentation level can be controlled by using the JsonGenerator:indent property

Default value: FALSE

### The `"root"` property

      "root"                     JsonNode*             : Read / Write

The root JsonNode to be used when constructing a JSON data stream.

Since 0.4
