updateChecksum();
The updateChecksum method of the JadeBytes class calculates the MD5 checksum for the current binary contents of a singleFile instance and updates the stored checksum to match. It does nothing for shared file instances.
The following example shows the use of the updateChecksum method.
vars bytes : MyJadeBytes; begin beginTransaction; create bytes persistent; bytes.singleFile := true; bytes.appendData("This is content".Binary); write bytes.matchChecksum(); // Writes "false" bytes.updateChecksum(); write bytes.matchChecksum() // Writes "true"; epilog abortTransaction; end;
