Class HtmlTableFormatter

java.lang.Object
  org.apache.hadoop.hbase.hql.formatter.HtmlTableFormatter

All Implemented Interfaces:

TableFormatter

public class HtmlTableFormatter
extends Object
implements TableFormatter

Formatter that outputs data inside an HTML table. If only a single cell result, then no formatting is done. Presumption is that client manages serial access outputting tables. Does not close passed Writer. Since hbase columns have no typing, the formatter presumes a type of UTF-8 String. If cells contain images, etc., this formatter will mangle their display.

TODO: Uses xmlenc. Hopefully it flushes every so often (Claims its a stream-based outputter). Verify.
