Detailed Description

\inmodule QtCore

\reentrant

Since: 5.0

The QJsonValue class encapsulates a value in JSON.

\compares equality \compareswith equality QJsonValueConstRef QJsonValueRef \endcompareswith

A value in JSON can be one of 6 basic types:

JSON is a format to store structured data. It has 6 basic data types:

\list

bool QJsonValue::Bool
double QJsonValue::Double
string QJsonValue::String
array QJsonValue::Array
object QJsonValue::Object
null QJsonValue::Null \endlist

A value can represent any of the above data types. In addition, QJsonValue has one special flag to represent undefined values. This can be queried with isUndefined().

The type of the value can be queried with type() or accessors like isBool(), isString(), and so on. Likewise, the value can be converted to the type stored in it using the toBool(), toString() and so on.

Values are strictly typed internally and contrary to QVariant will not attempt to do any implicit type conversions. This implies that converting to a type that is not stored in the value will return a default constructed return value.

Member Enumeration Documentation

◆ Type

enum QJsonValue::Type

This enum describes the type of the JSON value.

\value Null A Null value \value Bool A boolean value. Use toBool() to convert to a bool. \value Double A number value. Use toDouble() to convert to a double, or toInteger() to convert to a qint64. \value String A string. Use toString() to convert to a QString. \value Array An array. Use toArray() to convert to a QJsonArray. \value Object An object. Use toObject() to convert to a QJsonObject. \value Undefined The value is undefined. This is usually returned as an error condition, when trying to read an out of bounds value in an array or a non existent key in an object.
