Method Detail

isConfigurationAcceptable

public boolean isConfigurationAcceptable(T configuration,
                                         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<T extends DebugLogPublisherCfg>

Parameters:

configuration - 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.

addTraceSettings

public final void addTraceSettings(String scope,
                                   TraceSettings settings)

Adds a trace settings to the current set for a specified scope. If a scope is not specified, the settings will be set for the global scope. The global scope settings are used when no other scope matches.

Parameters:

scope - The scope for which to set the trace settings. This should be a fully-qualified class name, or null to set the trace settings for the global scope.

settings - The trace settings for the specified scope.

trace

public abstract void trace(TraceSettings settings,
                           String signature,
                           String sourceLocation,
                           String msg,
                           StackTraceElement[] stackTrace)

Log an arbitrary event in a method.

Parameters:

settings - The current trace settings in effect.

signature - The method signature.

sourceLocation - The location of the method in the source.

msg - The message to be logged.

stackTrace - The stack trace at the time the message is logged or null if its not available.

traceException

public abstract void traceException(TraceSettings settings,
                                    String signature,
                                    String sourceLocation,
                                    String msg,
                                    Throwable ex,
                                    StackTraceElement[] stackTrace)

Log a caught exception in a method.

Parameters:

settings - The current trace settings in effect.

signature - The method signature.

sourceLocation - The location of the method in the source.

msg - The message to be logged.

ex - The exception that was caught.

stackTrace - The stack trace at the time the exception is caught or null if its not available.
