| 57 | The QByteArray class provides an array of bytes.
|
|---|
| 58 | <p>
|
|---|
| 59 |
|
|---|
| 60 | <p> The QByteArray class provides an <a href="shclass.html#explicitly-shared">explicitly shared</a> array of bytes.
|
|---|
| 61 | It is useful for manipulating memory areas with custom data.
|
|---|
| 62 | QByteArray is implemented as a <a href="qmemarray.html">QMemArray</a><char>. See the <a href="qmemarray.html">QMemArray</a> documentation for further information.
