Constructor Detail

MasterWebHandler

public MasterWebHandler(JobExecutor.JobExecutionStatus status)

Method Detail

setLastPageLoad

public void setLastPageLoad(long value)

getLastPageLoad

public long getLastPageLoad()

waitForFinalPage

public void waitForFinalPage()

Waits a bit longer for someone to load a final status page.

This method should be called immediately after a job is complete. If the page was loaded recently and the job wasn't complete, this method will wait up to 15 seconds for the browser to load the indexing complete page, which has no auto-refresh logic. This avoids the ugly experience of showing a "cannot connect to server" error in the browser after indexing completes.
