Classes
class	JSONDefaultPrecision
	JSONDefaultPrecision is a singleton that provides a mechanism to control the default precision for output of floating-point JSON values. More...
struct	QueryValueResult
	A struct used for return value of getElementIfExists() More...
struct	QueryNumberResult
	A struct used for return value of getNumberElementIfExists() More...
class	IsAtomicSerializable< JSONValue >

Namespaces
	mira
	specialize cv::DataType for our ImgPixel and inherit from cv::DataType<Vec>

Typedefs
typedef json_spirit::mValue	Value
	A value is an abstract description of data in JSON (underlying data can either be one of the JSON base data types (int, double, string) or an json::Object, json::Array or null. More...
typedef json_spirit::mObject	Object
	A representation of an object (class, struct) in JSON. More...
typedef json_spirit::mArray	Array
	A representation of an array (vector) in JSON. More...
typedef json::Value	JSONValue
	Imports the json::Value type into mira namespace. More...
typedef json::Object	JSONObject
	Imports the json::Object type into mira namespace. More...
typedef json::Array	JSONArray
	Imports the json::Array type into mira namespace. More...

Functions
MIRA_BASE_EXPORT void	write (const Value &value, std::ostream &ioStream, bool formatted=false, int precision=-1)
	Writes a json::Value into a given stream using the JSON format. More...
MIRA_BASE_EXPORT std::string	write (const Value &value, bool formatted=false, int precision=-1)
	Writes a json::Value into a string using the JSON format. More...
MIRA_BASE_EXPORT void	read (const std::string &s, Value &oValue)
	Read a json::Value from a string that contains JSON format. More...
MIRA_BASE_EXPORT void	read (std::istream &ioStream, Value &oValue)
	Read a json::Value from a stream that contains JSON format. More...
MIRA_BASE_EXPORT void	read (std::string::const_iterator &begin, std::string::const_iterator &end, Value &oValue)
	Read a json::Value from a string iterator range that contains JSON format. More...
MIRA_BASE_EXPORT Value	getElement (const Value &iValue, const std::string &elementName)
	Get a json::Value element/member from a json::Value Syntax: More...
MIRA_BASE_EXPORT bool	hasElement (const Value &iValue, const std::string &element)
	Query existence of element/member in a json::Value Use this variant to only query whether the element exists, avoiding exceptions. More...
MIRA_BASE_EXPORT QueryValueResult	getElementIfExists (const Value &iValue, const std::string &elementName)
	Get a json::Value element/member from a json::Value if it exists, otherwise the returned result will contain the error string. More...
MIRA_BASE_EXPORT double	getNumberElement (const Value &iValue, const std::string &elementName)
	Get a number element/member from a json::Value See getElement() for basic syntax. More...
MIRA_BASE_EXPORT bool	hasNumberElement (const Value &iValue, const std::string &element)
	Query existence of number element/member in a json::Value Use this variant to only query whether the element exists and is a number, avoiding exceptions. More...
MIRA_BASE_EXPORT QueryNumberResult	getNumberElementIfExists (const Value &iValue, const std::string &elementName)
	Get a number element/member from a json::Value if it exists, otherwise the returned result will contain the error string. More...
