## Class SubFilter

- java.lang.Object
- - net.sf.okapi.common.filters.SubFilter

- All Implemented Interfaces:
    IFilter

      public class SubFilter
      extends java.lang.Object
      implements IFilter

  Adapter that converts any `IFilter` into a subfilter (a filter called from another `IFilter`). Specific implementations can implement this class and override any needed methods to transform `Event`s as they are produced. This class should be used to wrap filters that use `GenericSkeleton` and its subclasses. If a different type of skeleton is used or id/name generation logic should be changed, subclass this class.

          public void open(RawDocument input)

      Description copied from interface: `IFilter`
      Opens the input document described in a give RawDocument object. Skeleton information is always created when you use this method.
      Specified by:
        `open` in interface `IFilter`
      Parameters:
        `input` - The RawDocument object to use to open the document.
