Method Detail

performOperation in class org.pentaho.mantle.client.commands.AbstractCommand

performOperation

protected void performOperation(boolean feedback)

Specified by:

performOperation in class org.pentaho.mantle.client.commands.AbstractCommand

getPollingInterval

public Integer getPollingInterval()

setPollingInterval

public void setPollingInterval(Integer pollingInterval)

getNextCheckShift

protected int getNextCheckShift()

If the session is expired returns a negative value. If the session is not expired returns a time left before expiration. If the cookie is not set returns a default polling interval.

Returns:

time shift for the next check

getClientTime

protected long getClientTime()

setClientTimeOffset

protected void setClientTimeOffset()

Don't be fooled with a System.currentTimeMillis() - in GWT it's a client side time. To eliminate a possible client clock desynchronization effect we need to calculate an offset between client and server time. Also there always will be a small positive offset equal to a time between the page load nad servlet invocation.

In case of any unpredicted situation the offset is set to 0.

getCookie

protected String getCookie(String name)

setCookie

protected void setCookie(String name,
                         String value)
