Represents a JSON value.
This class is a discriminated union wrapper that can represents a:
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 resize and initialized with nullValue. resize() can be used to enlarge or truncate an arrayValue.
The get() methods can be used to obtanis 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.

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:
Default constructor initialization must be equivalent to: memset( this, 0, sizeof(Value) ) This optimization is used in ValueInternalMap fast allocator.
| Json::Value::Value | ( | const char * | beginValue, |
| const char * | endValue ) |
| Json::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. Example of usage:
| Value::Int Json::Value::asInt | ( | ) | const |
| Value::Int64 Json::Value::asInt64 | ( | ) | const |
| LargestInt Json::Value::asLargestInt | ( | ) | const |

| Value & Json::Value::operator[] | ( | ArrayIndex | index | ) |
Access an array element (zero based index ).
If the array contains less than index element, then null value are inserted in the array so that its size is index+1. (You may need to say 'value[0u]' to get your compiler to distinguish this from the operator[] which takes a string.)
| const Value & Json::Value::operator[] | ( | ArrayIndex | index | ) | const |
| Value & Json::Value::operator[] | ( | const char * | key | ) |
| const Value & Json::Value::operator[] | ( | const char * | key | ) | const |
| Value & Json::Value::operator[] | ( | const StaticString & | key | ) |
Access an object value by name, create a null member if it does not exist.
If the object as no entry for that name, then the member name used to store the new entry is not duplicated. Example of use:
| Value & Json::Value::operator[] | ( | const std::string & | key | ) |
| const Value & Json::Value::operator[] | ( | const std::string & | key | ) | const |
| Value & Json::Value::operator[] | ( | int | index | ) |
Access an array element (zero based index ).
If the array contains less than index element, then null value are inserted in the array so that its size is index+1. (You may need to say 'value[0u]' to get your compiler to distinguish this from the operator[] which takes a string.)

| Value Json::Value::removeMember | ( | const char * | key | ) |
| Value Json::Value::removeMember | ( | const std::string & | key | ) |
