Member Function Documentation

bool MFileDataStore::isReadable

(

)

const

Queries if this data store is readable. If this method returns true you can use the reading methods of this class (value, allKeys, contains). If this method returns false, the reading methods don't provide the real data.

See also:

value, allKeys, contains

Returns:

true if the data store can be read.

Definition at line 274 of file mfiledatastore.cpp.

{
    Q_D(const MFileDataStore);
    return d->settings.status() == QSettings::NoError;
}

bool MFileDataStore::isWritable

(

)

const

Queries if this data store is writable. If this method returns true you can use the writing methods of this class (setValue, remove, clear). If this method returns false, the writing methods don't modify the data store.

See also:

setValue, remove, clear

Returns:

true if the data store can be written.

Definition at line 280 of file mfiledatastore.cpp.

{
    Q_D(const MFileDataStore);
    return d->settings.isWritable() && d->settings.status() == QSettings::NoError;
}
