bool KMemFile::isSequential (  )  const [virtual]

overload from QIODevice.

As KMemFile is a random access device, it returns false

Definition at line 136 of file kmemfile.cpp.

bool KMemFile::open ( OpenMode  mode  )  [virtual]

overload from QIODevice.

Parameters:
 mode only QIODevice::ReadOnly is accepted

Reimplemented from QIODevice.

Definition at line 141 of file kmemfile.cpp.

qint64 KMemFile::readData ( char *  data,
qint64  maxSize 
) [protected, virtual]

Reimplemented from QIODevice.

Definition at line 218 of file kmemfile.cpp.

bool KMemFile::seek ( qint64  pos  )  [virtual]

overload from QIODevice.

Sets the current read/write position to pos

Parameters:
 pos the new read/write position

Reimplemented from QIODevice.

Definition at line 202 of file kmemfile.cpp.

qint64 KMemFile::size (  )  const [virtual]

overload from QIODevice.

Returns the size of the file.

Definition at line 213 of file kmemfile.cpp.

qint64 KMemFile::writeData ( const char *  data,
qint64  maxSize 
) [protected, virtual]

Reimplemented from QIODevice.

Definition at line 231 of file kmemfile.cpp.
