class | ValueIteratorBase |
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 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 member keys of an object using the getMemberNames() method.

using Json::Value::Members = std::vector<String> |
using Json::Value::UInt = Json::UInt |
using Json::Value::UInt64 = Json::UInt64 |
using Json::Value::value_type = std::string |
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.
