Class XmlLogger

java.lang.Object
org.apache.tools.ant.XmlLogger
All Implemented Interfaces:
EventListener, BuildListener, BuildLogger

public class XmlLogger extends Object implements BuildLogger
Generates a file in the current directory with an XML description of what happened during a build. The default filename is "log.xml", but this can be overridden with the property XmlLogger.file. This implementation assumes in its sanity checking that only one thread runs a particular target/task at a time. This is enforced by the way that parallel builds and antcalls are done - and indeed all but the simplest of tasks could run into problems if executed in parallel.

    Method
    Description
    void
    Fired when the build finishes, this adds the time taken and any error stacktrace to the build element and writes the document to disk.
    void
    Fired when the build starts, this builds the top-level element for the document and remembers the time of the start of the build.
    int
     
    void
    Fired when a message is logged, this adds a message element to the most appropriate parent element (task, target or build) and records the priority and text of the message.
    void
    setEmacsMode(boolean emacsMode)
    Ignore emacs mode, as it has no meaning in XML format
    void
    Ignore error print stream.
    void
    Set the logging level when using this as a Logger
    void
    Set the output stream to which logging output is sent when operating as a logger.
    void
    Fired when a target finishes building, this adds the time taken and any error stacktrace to the appropriate target element in the log.
    void
    Fired when a target starts building, this pushes a timed element for the target onto the stack of elements for the current thread, remembering the current time and the name of the target.
    void
    Fired when a task finishes building, this adds the time taken and any error stacktrace to the appropriate task element in the log.
    void
    Fired when a task starts building, this pushes a timed element for the task onto the stack of elements for the current thread, remembering the current time and the name of the task.
