Usage

From source file:org.kiji.rest.resources.RowsResource.java

/**
 * POSTs JSON body to row(s): performs create and update.
 * The input JSON blob can either represent a single KijiRestRow or a list of KijiRestRows.
 *
 * For example, a single KijiRestRow:/*from   w w w.j  a v  a  2  s .c o m*/
 * {
 *   "entityId":"hbase=hex:8c2d2fcc2c150efb49ce0817e1823d46",

 * A list of KijiRestRows:
 * [
