    • globalInfo

      public String globalInfo()
      Returns a string describing this filter
      返回:
      a description of the filter suitable for displaying in the explorer/experimenter gui
    • getCapabilities

      public Capabilities getCapabilities()
      Returns the Capabilities of this filter.
      指定者:
      getCapabilities 在接口中 CapabilitiesHandler
      覆盖:
      getCapabilities 在类中 Filter
      返回:
      the capabilities of this object

    • setInputFormat

      public boolean setInputFormat(Instances instanceInfo) throws Exception
      Sets the format of the input instances.
      覆盖:
      setInputFormat 在类中 Filter
      参数:
      instanceInfo - an Instances object containing the input instance structure (any instances contained in the object are ignored - only the structure is required).
      返回:
      true if the outputFormat may be collected immediately
      抛出:
      Exception - if something goes wrong
    • input

      public boolean input(Instance instance)
      Input an instance for filtering. Ordinarily the instance is processed and made available for output immediately. Some filters require all instances be read before producing output.
      覆盖:
      input 在类中 Filter
      参数:
      instance - the input instance
      返回:
      true if the filtered instance may now be collected with output().
      抛出:
      IllegalStateException - if no input format has been defined.
    • toSource

      public String toSource(String className, Instances data) throws Exception
      Returns a string that describes the filter as source. The filter will be contained in a class with the given name (there may be auxiliary classes), and will contain two methods with these signatures:
      
       // converts one row
       public static Object[] filter(Object[] i);
       // converts a full dataset (first dimension is row index)
       public static Object[][] filter(Object[][] i);
       
      where the array i contains elements that are either Double, String, with missing values represented as null. The generated code is public domain and comes with no warranty.
      指定者:
      toSource 在接口中 Sourcable
      参数:
      className - the name that should be given to the source class.
      data - the dataset used for initializing the filter
      返回:
      the object source described by a string
      抛出:
      Exception - if the source can't be computed
    • getRevision

      public String getRevision()
      Returns the revision string.
      指定者:
      getRevision 在接口中 RevisionHandler
      覆盖:
      getRevision 在类中 Filter
      返回:
      the revision
    • main

      public static void main(String[] argv)
      Main method for testing this class.
      参数:
      argv - should contain arguments to the filter: use -h for help
