Class OperatorPresentFilter

java.lang.Object
org.ka2ddo.yaac.filter.Filter
org.ka2ddo.yaac.filter.OperatorPresentFilter
All Implemented Interfaces:
Cloneable

public class OperatorPresentFilter extends Filter implements Cloneable
This filter optionally eliminates all messages from unmanned stations. Note this may not be a particularly useful filter, as very few APRS stations use the 'O' overlay to indicate there is a human operator at the station.

    • getFilterTypeTagName

      public String getFilterTypeTagName()
      Get the ResourceBundle resource name for looking up the localized name of this Filter.
      Specified by:
      getFilterTypeTagName in class Filter
      Returns:
      String resource name
    • getFilterHelpTagName

      public String getFilterHelpTagName()
      Report a tag name used to look up JavaHelp for a filter editor.

      String name (as defined in HelpMap.jhm) for this filter's online help, or null if there is no filter specific help
    • setToPassall

      public void setToPassall()
      Reset the filter to a configuration that would pass the maximum amount of messages, packets, and stations.
      Specified by:
      setToPassall in class Filter
    • canRejectSome

      public boolean canRejectSome()
      Specifies that this filter may reject some stations, messages, and/or frames. Used to tell combining filters whether a sub-filter is in passall mode and therefore doesn't need to be checked for every call to the combiner, thereby saving CPU time when filtering when most filters are in passall mode.
      Overrides:
      canRejectSome in class Filter
      Returns:
      boolean true if this filter is currently capable of rejecting something
