      com.ctc.wstx.util.LineSuppressWriter

public class LineSuppressWriter

extends java.io.Writer

Simple decorator Writer, that can optionally suppress empty lines (lines with only white space content); configuration is done by specifying what is the maximum number of consequtive empty lines allowed. Setting this value to 0 will filter out all lines; setting it to, say, Integer.MAX_VALUE essentially does nothing.

Note: only ascii white space (space char and below) are considered white space.
