Description copied from interface: LogPublisher

Indicates whether the provided configuration is acceptable for this log publisher. It should be possible to call this method on an uninitialized log publisher instance in order to determine whether the log publisher would be able to use the provided configuration.

Specified by:

isConfigurationAcceptable in interface LogPublisher<FileBasedDebugLogPublisherCfg>

Overrides:

isConfigurationAcceptable in class DebugLogPublisher<FileBasedDebugLogPublisherCfg>

Parameters:

config - The log publisher configuration for which to make the determination.

unacceptableReasons - A list that may be used to hold the reasons that the provided configuration is not acceptable.

Returns:

true if the provided configuration is acceptable for this log publisher, or false if not.

initializeLogPublisher

public void initializeLogPublisher(FileBasedDebugLogPublisherCfg cfg,
                                   ServerContext serverContext)
