      • addReadFilter

        public void addReadFilter​(Filter filter)
        Description copied from interface: ReadFiltered
        Installs a read filter defining a transformation to be applied by the read method of the channel end. The filter will be appended to the end of the current list, making it the last to be applied.
        Specified by:
        addReadFilter in interface ReadFiltered
        Overrides:
        addReadFilter in class FilteredChannelInputWrapper
        Parameters:
        filter - the filter to be installed; may not be null.
      • addReadFilter

        public void addReadFilter​(Filter filter,
                                  int index)
        Description copied from interface: ReadFiltered
        Installs a read filter defining a transformation to be applied by the read method of the channel end at a specific index. If there is already a filter at that index position the existing filters are shifted to make room. If the index is greater than the number of filters already installed the filter is placed at the end.
        Specified by:
        addReadFilter in interface ReadFiltered
        Overrides:
        addReadFilter in class FilteredChannelInputWrapper
        Parameters:
        filter - the filter to be installed; may not be null.
        index - the zero based index; may not be negative.

        public void removeReadFilter​(Filter filter)
        Description copied from interface: ReadFiltered
        Removes the first read filter (lowest index) matching the filter given as a parameter. The filter removed, r, will satisfy the condition r.equals (filter). The remaining filters are shifted to close the gap in the index allocation.
        Specified by:
        removeReadFilter in interface ReadFiltered
        Overrides:
        removeReadFilter in class FilteredChannelInputWrapper
