event - The LogEvent.

getFileName

public String getFileName()

Returns the File name for the Appender.

Returns:

The file name.

getFilePattern

public String getFilePattern()

Returns the file pattern used when rolling over.

Returns:

The file pattern.

getTriggeringPolicy

public <T extends TriggeringPolicy> T getTriggeringPolicy()

Returns the triggering policy.

Type Parameters:

T - TriggeringPolicy type

Returns:

The TriggeringPolicy

Use newBuilder().

Creates a RollingFileAppender.

Parameters:

fileName - The name of the file that is actively written to. (required).

filePattern - The pattern of the file name to use on rollover. (required).

append - If true, events are appended to the file. If false, the file is overwritten when opened. Defaults to "true"

name - The name of the Appender (required).

bufferedIO - When true, I/O will be buffered. Defaults to "true".

bufferSizeStr - buffer size for buffered IO (default is 8192).

immediateFlush - When true, events are immediately flushed. Defaults to "true".

policy - The triggering policy. (required).

strategy - The rollover strategy. Defaults to DefaultRolloverStrategy.

layout - The layout to use (defaults to the default PatternLayout).

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:

A RollingFileAppender.

newBuilder
