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;
