Method Detail

getToolStartupTextErrorPublisher

public static TextErrorLogPublisher getToolStartupTextErrorPublisher(TextWriter writer)

Returns a new text error log publisher which will print all messages to the provided writer. This publisher should be used by tools.

Parameters:

writer - The text writer where the message will be written to.

Returns:

A new text error log publisher which will print all messages to the provided writer.

getServerStartupTextErrorPublisher

public static TextErrorLogPublisher getServerStartupTextErrorPublisher(TextWriter writer)

Returns a new text error log publisher which will print only notices, severe warnings and errors, and fatal errors messages to the provided writer. This less verbose publisher should be used by the directory server during startup.

Parameters:

writer - The text writer where the message will be written to.

Returns:

A new text error log publisher which will print only notices, severe warnings and errors, and fatal errors messages to the provided writer.

initializeLogPublisher

public void initializeLogPublisher(FileBasedErrorLogPublisherCfg config,
                                   ServerContext serverContext)
                            throws ConfigException,
                                   InitializationException

Description copied from interface: LogPublisher

Initializes this publisher provider based on the information in the provided debug publisher configuration.

Specified by:

initializeLogPublisher in interface LogPublisher<FileBasedErrorLogPublisherCfg>

Parameters:

config - The publisher configuration that contains the information to use to initialize this publisher.

serverContext - The server context.

Throws:

ConfigException - If an unrecoverable problem arises in the process of performing the initialization as a result of the server configuration.

InitializationException - If a problem occurs during initialization that is not related to the server configuration.

isConfigurationAcceptable

public boolean isConfigurationAcceptable(FileBasedErrorLogPublisherCfg config,
                                         List<LocalizableMessage> unacceptableReasons)

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<FileBasedErrorLogPublisherCfg>

Overrides:

isConfigurationAcceptable in class ErrorLogPublisher<FileBasedErrorLogPublisherCfg>

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.

isConfigurationChangeAcceptable

public boolean isConfigurationChangeAcceptable(FileBasedErrorLogPublisherCfg config,
                                               List<LocalizableMessage> unacceptableReasons)

Description copied from interface: ConfigurationChangeListener

Indicates whether the proposed change to the configuration is acceptable to this change listener.

Specified by:

isConfigurationChangeAcceptable in interface ConfigurationChangeListener<FileBasedErrorLogPublisherCfg>

Parameters:

config - The new configuration containing the changes.

unacceptableReasons - A list that can be used to hold messages about why the provided configuration is not acceptable.

Returns:

Returns true if the proposed change is acceptable, or false if it is not.

applyConfigurationChange

public ConfigChangeResult applyConfigurationChange(FileBasedErrorLogPublisherCfg config)

Description copied from interface: ConfigurationChangeListener

Applies the configuration changes to this change listener.

Specified by:

Parameters:

config - The new configuration containing the changes.

Returns:

Returns information about the result of changing the configuration.

close
