Method Details

addMarker

public LoggingEventBuilder addMarker(Marker marker)

Add a marker to the current logging event being built.

It is possible to add multiple markers to the same logging event.

Specified by:

addMarker in interface LoggingEventBuilder

Parameters:

marker - the marker to add

Returns:

a LoggingEventBuilder, usually this.

setCause

public LoggingEventBuilder setCause(Throwable t)

Description copied from interface: LoggingEventBuilder

Set the cause for the logging event being built.

Specified by:

setCause in interface LoggingEventBuilder

Parameters:

t - a throwable

Returns:

a LoggingEventBuilder, usually this.

addArgument

public LoggingEventBuilder addArgument(Object p)

Description copied from interface: LoggingEventBuilder

Add an argument to the event being built.

Specified by:

addArgument in interface LoggingEventBuilder

Parameters:

p - an Object to add.

Returns:

a LoggingEventBuilder, usually this.

addArgument

public LoggingEventBuilder addArgument(Supplier<?> objectSupplier)

Description copied from interface: LoggingEventBuilder

Add an argument supplier to the event being built.

Specified by:

addArgument in interface LoggingEventBuilder

Parameters:

objectSupplier - an Object supplier to add.

Returns:

a LoggingEventBuilder, usually this.

addKeyValue

public LoggingEventBuilder addKeyValue(String key,
 Object value)

Description copied from interface: LoggingEventBuilder

Add a key value pair to the event being built.

Specified by:

addKeyValue in interface LoggingEventBuilder

Parameters:

key - the key of the key value pair.

value - the value of the key value pair.

Returns:

a LoggingEventBuilder, usually this.

addKeyValue

public LoggingEventBuilder addKeyValue(String key,
 Supplier<Object> value)

Description copied from interface: LoggingEventBuilder

Add a key value pair to the event being built.

Specified by:

addKeyValue in interface LoggingEventBuilder

Parameters:

key - the key of the key value pair.

value - a supplier of a value for the key value pair.

Returns:

a LoggingEventBuilder, usually this.

setCallerBoundary

public void setCallerBoundary(String fqcn)

Description copied from interface: CallerBoundaryAware

Add a fqcn (fully qualified class name) to this event, presumed to be the caller boundary.

Specified by:

setCallerBoundary in interface CallerBoundaryAware

Parameters:

fqcn -

log

public void log()

Description copied from interface: LoggingEventBuilder

After the logging event is built, performs actual logging. This method must be called for logging to occur. If the call to LoggingEventBuilder.log() is omitted, a LoggingEvent will be built but no logging will occur.

Specified by:

log in interface LoggingEventBuilder

setMessage

public LoggingEventBuilder setMessage(String message)

Description copied from interface: LoggingEventBuilder

Sets the message of the logging event.

Specified by:

setMessage in interface LoggingEventBuilder

setMessage

public LoggingEventBuilder setMessage(Supplier<String> messageSupplier)

Description copied from interface: LoggingEventBuilder

Sets the message of the event via a message supplier.

Specified by:

setMessage in interface LoggingEventBuilder

Parameters:

messageSupplier - supplies a String to be used as the message for the event

log

public void log(String message)

Description copied from interface: LoggingEventBuilder

Equivalent to calling LoggingEventBuilder.setMessage(String) followed by LoggingEventBuilder.log();

Specified by:

log in interface LoggingEventBuilder

Parameters:

message - the message to log

log

public void log(String message,
 Object arg)

Description copied from interface: LoggingEventBuilder

Equivalent to calling LoggingEventBuilder.setMessage(String) followed by LoggingEventBuilder.addArgument(Object)} and then LoggingEventBuilder.log()

Specified by:

log in interface LoggingEventBuilder

Parameters:

message - the message to log

arg - an argument to be used with the message to log

log

public void log(String message,
 Object arg0,
 Object arg1)

Description copied from interface: LoggingEventBuilder

Equivalent to calling LoggingEventBuilder.setMessage(String) followed by two calls to LoggingEventBuilder.addArgument(Object) and then LoggingEventBuilder.log()

Specified by:

log in interface LoggingEventBuilder

Parameters:

message - the message to log

arg0 - first argument to be used with the message to log

arg1 - second argument to be used with the message to log

log

public void log(String message,
 Object... args)

Description copied from interface: LoggingEventBuilder

Equivalent to calling LoggingEventBuilder.setMessage(String) followed by zero or more calls to LoggingEventBuilder.addArgument(Object) (depending on the size of args array) and then LoggingEventBuilder.log()

Specified by:

log in interface LoggingEventBuilder

Parameters:

message - the message to log

args - a list (actually an array) of arguments to be used with the message to log

log

public void log(Supplier<String> messageSupplier)

Description copied from interface: LoggingEventBuilder

Equivalent to calling LoggingEventBuilder.setMessage(Supplier) followed by LoggingEventBuilder.log()

Specified by:

log in interface LoggingEventBuilder

Parameters:

messageSupplier - a Supplier returning a message of type String

log

protected void log(LoggingEvent aLoggingEvent)
