Method Details

stop

public boolean stop(long timeout,
 TimeUnit timeUnit)

Description copied from class: AbstractFilterable

Cleanup the Filter.

Specified by:

stop in interface LifeCycle2

Overrides:

stop in class AbstractOutputStreamAppender<MemoryMappedFileManager>

Parameters:

timeout - the maximum time to wait

timeUnit - the time unit of the timeout argument

Returns:

true if the receiver was stopped cleanly and normally, false otherwise.

getFileName

public String getFileName()

Returns the file name this appender is associated with.

Returns:

The File name.

getRegionLength

public int getRegionLength()

Returns the length of the memory mapped region.

Returns:

the length of the memory mapped region

createAppender

@Deprecated
public static <B extends MemoryMappedFileAppender.Builder<B>>
MemoryMappedFileAppender createAppender(String fileName,
 String append,
 String name,
 String immediateFlush,
 String regionLengthStr,
 String ignore,
 Layout<? extends Serializable> layout,
 Filter filter,
 String advertise,
 String advertiseURI,
 Configuration config)

Deprecated.

Use newBuilder().

Create a Memory Mapped File Appender.

Parameters:

fileName - The name and path of the file.

append - "True" if the file should be appended to, "false" if it should be overwritten. The default is "true".

name - The name of the Appender.

immediateFlush - "true" if the contents should be flushed on every write, "false" otherwise. The default is "false".

regionLengthStr - The buffer size, defaults to 33554432.

ignore - If "true" (default) exceptions encountered when appending events are logged; otherwise they are propagated to the caller.

layout - The layout to use to format the event. If no layout is provided the default PatternLayout will be used.

filter - The filter, if any, to use.

advertise - "true" if the appender configuration should be advertised, "false" otherwise.

advertiseURI - The advertised URI which can be used to retrieve the file contents.

config - The Configuration.

Returns:

The FileAppender.
