Examples of weka.filters.Filter.input()

weka.filters.Filter.input()

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, in which case output instances should be collected after calling batchFinished(). If the input marks the start of a new batch, the output queue is cleared. This default implementation assumes all instance conversion will occur when batchFinished() is called. @param instance the input instance @return true if the filtered instance may now becollected with output(). @throws NullPointerException if the input format has not beendefined. @throws Exception if the input instance was not of the correct format or if there was a problem with the filtering.
