      getAttribute in class LogFactory
      Parameters:

    • getAttributeNames

      public String[] getAttributeNames()
      Description copied from class: LogFactory
      Gets an array containing the names of all currently defined configuration attributes. If there are no such attributes, a zero length array is returned.
      Specified by:
      getAttributeNames in class LogFactory
      Returns:
      an array containing the names of all currently defined configuration attributes

    • getInstance

      public Log getInstance(Class<?> clazz)
      Description copied from class: LogFactory
      Convenience method to derive a name from the specified class and call getInstance(String) with it.
      Specified by:
      getInstance in class LogFactory
      Parameters:
      clazz - Class for which a suitable Log name will be derived
      Returns:
      a name from the specified class.

    • getInstance

      public Log getInstance(String name)
      Description copied from class: LogFactory
      Constructs (if necessary) and return a Log instance, using the factory's current set of configuration attributes.

      NOTE - Depending upon the implementation of the LogFactory you are using, the Log instance you are returned may or may not be local to the current application, and may or may not be returned again on a subsequent call with the same name argument.

      Specified by:
      getInstance in class LogFactory
      Parameters:
      name - Logical name of the Log instance to be returned (the meaning of this name is only known to the underlying logging implementation that is being wrapped)
      Returns:
      a Log instance.

    • release

      public void release()
      This method is supposed to clear all loggers. In this implementation it will clear all the logger wrappers but the loggers managed by the underlying logger context will not be.
      Specified by:
      release in class LogFactory

    • removeAttribute

      public void removeAttribute(String name)
      Description copied from class: LogFactory
      Remove any configuration attribute associated with the specified name. If there is no such attribute, no action is taken.
      Specified by:
      removeAttribute in class LogFactory
      Parameters:
      name - Name of the attribute to remove

    • setAttribute

      public void setAttribute(String name, Object value)
      Description copied from class: LogFactory
      Sets the configuration attribute with the specified name. Calling this with a null value is equivalent to calling removeAttribute(name).
      Specified by:
      setAttribute in class LogFactory
      Parameters:
      name - Name of the attribute to set
      value - Value of the attribute to set, or null to remove any setting for this attribute
