matches
Ensures that settings of 2 servers match each other so that the servers are capable of performing a transfer between themselves. The parameters of both sessions must either both be set correctly, or both undefined.
Detailed rules: Two sessions match if their transfer type, mode, and protection buffer sizes match. Additionally, if one party is passive, the other must be active. If any of the variables are set to SERVER_DEFAULT, sessions are considered matching.- Throws:
ClientException
- if sessions do not match
-
compareTransferParams
defines how to compare parameters: authorized, PBSZ, MODE, TYPE- Throws:
ClientException
-
compareServerMode
checks that active / passive sides are correctly set- Throws:
ClientException
