\internal
QQmlBindEntryContent can store one of QV4::Value, QVariant, QQmlAnyBinding, or nothing,
as denoted by QQmlBindEntryKind. It expects the calling code to know what is stored at
any time. On each method invocation, the current kind has to be passed as last parameter
and the new kind is returned.

\qmltype LoggingCategory
\ingroup qml-utility-elements
\inqmlmodule QtQml
\brief Defines a logging category in QML.
\since 5.8
A logging category can be passed to console.log() and friends as the first argument.
If supplied to the logger the LoggingCategory's name will be used as logging category.
Otherwise the default logging category will be used.
\qml
import QtQuick
Item {
LoggingCategory {
id: category
name: "com.qt.category"
defaultLogLevel: LoggingCategory.Warning
}
Component.onCompleted: {
console.log(category, "log message");
console.warn(category, "warning message");
}
}
\endqml
By default this outputs only \c{com.qt.category: warning message}. The
\c{log message} is suppressed due to the \l{defaultLogLevel}. You can,
however, configure log levels for QML logging categories the same way
you can configure them for
\l{QLoggingCategory#configuring-categories}{QLoggingCategory}.
\note As the creation of objects is expensive, it is encouraged to put the needed
LoggingCategory definitions into a singleton and import this where needed.

\qmltype Timer
\inqmlmodule QtQml
\ingroup qtquick-interceptors
\brief Triggers a handler at a specified interval.
A Timer can be used to trigger an action either once, or repeatedly
at a given interval.
Here is a Timer that shows the current date and time, and updates
the text every 500 milliseconds. It uses the JavaScript \c Date
object to access the current time.
\qml
import QtQuick 2.0
Item {
Timer {
interval: 500; running: true; repeat: true
onTriggered: time.text = Date().toString()
}
Text { id: time }
}
\endqml
The Timer type is synchronized with the animation timer. Since the animation
timer is usually set to 60fps, the resolution of Timer will be
at best 16ms.
If the Timer is running and one of its properties is changed, the
elapsed time will be reset. For example, if a Timer with interval of
1000ms has its \e repeat property changed 500ms after starting, the
elapsed time will be reset to 0, and the Timer will be triggered
1000ms later.
