Method Detail

pamStart

public void pamStart()

Description copied from class: PamProcess

Called for each process to tell it to start (may not be necessary for processes which are listening for data anyway).

Specified by:

pamStart in class PamProcess

pamStop

public void pamStop()

Description copied from class: PamProcess

saveSettingsToDB

public boolean saveSettingsToDB()

Called from the settings manager whenever settings would normally be saved to file. Just saves the latest of all PAMGUARD settings, first deleting any other settings in the logLastSettings table.

The logSettings object does a slightly different task of always storing the current PAMGAURD settings in a table which grows and grows, giving a permanent record of PAMGUARD settings over time.

Unlike the settings in the growing table of logSettings, the settings stored from logLastSettings are also stored when viewer or mixed mode is exited.

Returns:

true if successful.
