updateTokenLock

public void updateTokenLock(org.tentackle.common.Timestamp tokenExpiry,
 long userId,
 org.tentackle.common.Timestamp curTime)

Updates the token lock columns in the database record.
Will *NOT* log modification and *NOT* update the serial-counter! Must be called from within application where appropriate.

2 cases:

If expiry == 0, the "token" is released. True is returned if operation was successful and editedBy will hold 0 while editedSince holds the current (release) time. False is returned if token could not be released and nothing is changed. This is usually the case when another user holds the token (and indicates some logic errors in the application, btw.) EditedBy and editedSince are updated in the object to reflect the current values in the database. Notice: releasing an already released token is not considered to be an error. This will simply update the release timestamp.

If expiry > 0, a new token for the current user is requested. True is returned if the token could be exclusively acquired. EditedBy and editedSince are updated accordingly. If false: the object is in use by another user and editedSince and editedId holds this user and his timestamp. Notice: requesting an already requested token will simply renew the token.

The method does not check getTokenLockTimeout()! This is due to the application. Applications should use updateTokenLock(tokenExpiry). This is an internal implementation only.

Parameters:

tokenExpiry - holds the time the token will expire. Null to release token.

userId - is the current user (unused if tokenExpiry is null)

curTime - is the current system time

updateTokenLock

public void updateTokenLock(org.tentackle.common.Timestamp tokenExpiry)

Updates the token lock columns in the database record.
Will *NOT* log modification and *NOT* update the serial-counter! Must be called from within application where appropriate.

2 cases:

If expiry == 0, the "token" is released. True is returned if operation was successful and editedBy will hold 0 while editedSince holds the current (release) time. False is returned if token could not be released and nothing is changed. This is usually the case when another user holds the token (and indicates some logic errors in the application, btw.) EditedBy and editedSince are updated in the object to reflect the current values in the database. Notice: releasing an already released token is not considered to be an error. This will simply update the release timestamp.

If expiry > 0, a new token for the current user is requested. True is returned if the token could be exclusively acquired. EditedBy and editedSince are updated accordingly. If false: the object is in use by another user and editedSince and editedId holds this user and his timestamp. Notice: requesting an already requested token will simply renew the token.

The method does not check getTokenLockTimeout()! This is due to the application.

Parameters:

tokenExpiry - holds the time the token will expire. Null to release token.
