Method Detail

fix

public static void fix(File file)
                throws IOException

This function fixes the length information in Document / Array types in a BSON file.

The file generated by BsonGenerator does not contain the length information for Document / Array types. It simplifies document generation and improves performance.

Even though BsonParser and Bson4Jackson etc support this format, utilities such as bsondump do require the length information.

Parameters:

file - the file to be fixed.

Throws:

IOException - in case of I/O error.
