Member Function Documentation

void moost::container::mmd_section_writer_base::commit

(

)

[inline]

Commit the section

All data has been written to the section and the accessor can now finish writing the section to the dataset and updating the index.

This method should always be called explicitly in order to avoid hidden exceptions when it is called by the destructor.
