  • All Implemented Interfaces:
    SubTask
    public class CreateMemoryMappedFileAppenderTask
extends CreateFileAppenderTask

    A Rhino management sub task for creating a log appender writing to a memory-mapped file.

    Ant Parameters
    Attribute Type Description Required

    appendername

    String

    Name of the appender to create. This name must be unique.

    Yes.

    filename

    String

    The file to write to

    Yes.

    append

    boolean

    Append to the file if true, otherwise clear the file on open.

    No.

    immediateflush

    boolean

    Flush to disk after every message. Reduces the risk of data loss on system crash at the cost of performance.

    No.

    regionlength

    Integer

    The length of the mapped region. 256B-1GB. Default 32MB.

    No.

    ignoreexceptions

    boolean

    Log exceptions thrown by this appender then ignore them. If set to false propagate to the caller (used to support selective appenders e.g. FailoverAppender).

    No.

    failonerror

    boolean

    Flag to control failure behaviour. If 'true', the sub task will throw a BuildException when an error is encountered. If 'false', the sub task will throw a NonFatalBuildException instead of a BuildException under specific circumstances. See below for conditions (if any) which will cause a NonFatalBuildException.

    No. Default value is taken from the Rhino management parent task.
    Nested elements

    Description

    filter

    A filter to select events that will be reported by this appender.
