Package org.apache.log4j.chainsaw

Class ChainsawCyclicBufferTableModel

  • All Implemented Interfaces:
    java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener, javax.swing.table.TableModel, EventContainer, LoggerNameModel, SortTableModel
    class ChainsawCyclicBufferTableModel
extends javax.swing.table.AbstractTableModel
implements EventContainer, java.beans.PropertyChangeListener
    A CyclicBuffer implementation of the EventContainer.

    NOTE: This implementation prevents duplicate rows from being added to the model.

    Ignoring duplicates was added to support receivers which may attempt to deliver the same event more than once but can be safely ignored (for example, the database receiver when set to retrieve in a loop).

        public boolean addLoggerName​(java.lang.String loggerName)
        Description copied from interface: LoggerNameModel
        Attempts to add the loggerName to the model, and returns true if it does, i.e that the loggerName is new, otherwise it is ignored.

      • setRuleMediator

        public void setRuleMediator​(RuleMediator ruleMediator)
        Changes the underlying display rule in use. If there was a previous Rule defined, this Model removes itself as a listener from the old rule, and adds itself to the new rule (if the new Rule is not Null).
