Detailed Description

Represents a JSON value.

This class is a discriminated union wrapper that can represents a:

signed integer [range: Value::minInt - Value::maxInt]
unsigned integer (range: 0 - Value::maxUInt)
double
UTF-8 string
boolean
'null'
an ordered list of Value
collection of name/value pairs (javascript object)

The type of the held value is represented by a ValueType and can be obtained using type().

Values of an objectValue or arrayValue can be accessed using operator[]() methods. Non-const methods will automatically create the a nullValue element if it does not exist. The sequence of an arrayValue will be automatically resized and initialized with nullValue. resize() can be used to enlarge or truncate an arrayValue.

The get() methods can be used to obtain default value in the case the required element does not exist.

It is possible to iterate over the list of a objectValue values using the getMemberNames() method.

Note: Value string-length fit in size_t, but keys must be < 2^30. (The reason is an implementation detail.) A #CharReader will raise an exception if a bound is exceeded to avoid security holes in your app, but the Value API does not check bounds. That is the responsibility of the caller.

Constructor & Destructor Documentation

◆ Value() [1/12]

Value::Value ( ValueType type = nullValue )

Create a default Value of the given type.

This is a very useful constructor. To create an empty array, pass arrayValue. To create an empty object, pass objectValue. Another Value can then be set to this one by assignment. This is useful since clear() and resize() will not alter types.

Examples:

Json::Value null_value; // null
Json::Value arr_value(Json::arrayValue); // []
Json::Value obj_value(Json::objectValue); // {}

Definition at line 2717 of file jsoncpp.cpp.

Definition at line 2764 of file jsoncpp.cpp.

◆ Value() [7/12]

Value::Value ( const char * value )

Copy til first 0. (NULL causes to seg-fault.)

Definition at line 2769 of file jsoncpp.cpp.

◆ Value() [8/12]

Value::Value	(	const char *	begin,
		const char *	end
	)

Copy all, incl zeroes.

Definition at line 2774 of file jsoncpp.cpp.

◆ Value() [9/12]

Value::Value ( const StaticString & value )

Constructs a value from a static string.

Like other value string constructor but do not duplicate the string for internal storage. The given string must remain alive after the call to this constructor.

Note: This works only for null-terminated strings. (We cannot change the size of this class, so we have nowhere to store the length, which might be computed later for various operations.)

Example of usage:

static StaticString foo("some text");

Json::Value aValue(foo);

Definition at line 2786 of file jsoncpp.cpp.

◆ Value() [10/12]

Value::Value ( const std::string & value )
