Detailed Description

Class to store JSON objects as C++ objects.

This class is able to represent a JSON object in its entirety. Arrays and Maps store arrays and maps of JSON values.

There are methods to load a JSONValue from a UT_JSONParser and to save to a UT_JSONWriter object.

To load an entire JSON file into memory, you can do something like

UT_JSONIStream *is(utistream);
UT_JSONParser parser;
UT_JSONValue value;
if (!value.load(parser, *is))
        reportFailure(parser.getErrors());

To save a value:

UT_JSONWriterSubclass &os;

value.save(os);

Alternatively, it's possible to use the UT_JSONValue class from within other UT_JSONHandle classes. For example, when loading key/value pairs for an arbitrary map:

bool
my_handle::jsonKey(UT_JSONParser &parser, const char *token, int64)
{
     UT_String          keyword;
     UT_JSONValue       value;
     keyword.harden(token);
     if (!value.load(parser))
        return false;
     process(keyword, value);
     return true;
}

Member Function Documentation

UT_JSONValueArray* UT_JSONValue::addArrayChild ( const UT_StringHolder & map_key )

Adds a new array child to this value. The current value must be either an array or a map. If this value is an array, the map_key parameter is ignored. This is due to overly convoluted JSON syntax design.

UT_JSONValueMap* UT_JSONValue::addMapChild ( const UT_StringHolder & map_key )

Adds a new map child to this value. The current value must be either an array or a map. If this value is an array, the map_key parameter is ignored. This is due to overly convoluted JSON syntax design.

traverser UT_JSONValue::append ( const UT_JSONValue & v )

Insert a json value to the back of the contained array.

bool UT_JSONValue::appendArray ( const UT_JSONValue & v )

Add an element to an array (returns false if operation fails) The current value must be an array object

bool UT_JSONValue::appendMap	(	const UT_StringHolder &	key,

Add an element to a map (returns false if operation fails) The current value must be a map object

SYS_NO_DISCARD_RESULT traverser UT_JSONValue::begin ( void )
