# Obsolete Members for QStringRef

The following members of class QStringRef are obsolete. They are provided to keep old source code working. We strongly advise against using them in new code.

## Public Functions

`(obsolete)` QVector<QStringRef> | split(const QString &sep, QString::SplitBehavior behavior, Qt::CaseSensitivity cs = Qt::CaseSensitive) const
`(obsolete)` QVector<QStringRef> | split(QChar sep, QString::SplitBehavior behavior, Qt::CaseSensitivity cs = Qt::CaseSensitive) const
`(obsolete)` QByteArray | toAscii() const

## Member Function Documentation

### QVector<QStringRef> QStringRef::split(const QString &sep, QString::SplitBehavior behavior, Qt::CaseSensitivity cs = Qt::CaseSensitive) const

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This is an overloaded function.

Use QString::split(const QString &sep, Qt::SplitBehavior behavior, Qt::CaseSensitivity cs) instead.

This function was introduced in Qt 5.4.

### QVector<QStringRef> QStringRef::split(QChar sep, QString::SplitBehavior behavior, Qt::CaseSensitivity cs = Qt::CaseSensitive) const

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This is an overloaded function.

Use QString::split(QChar sep, Qt::SplitBehavior behavior, Qt::CaseSensitivity cs) instead.

This function was introduced in Qt 5.4.

### QByteArray QStringRef::toAscii() const

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Returns an 8-bit representation of the string as a QByteArray.

This function does the same as toLatin1().

Note that, despite the name, this function does not necessarily return an US-ASCII (ANSI X3.4-1986) string and its result may not be US-ASCII compatible.

This function was introduced in Qt 4.8.

See also toLatin1(), toUtf8(), toLocal8Bit(), and QTextCodec.
