Examples of org.apache.storm.hbase.common.ColumnList$Counter

org.apache.storm.hbase.common.ColumnList
Represents a list of HBase columns. There are two types of columns, standard and counter. Standard columns have column family (required), qualifier (optional), timestamp (optional), and a value (optional) values. Counter columns have column family (required), qualifier (optional), and an increment (optional, but recommended) values. Inserts/Updates can be added via the addColumn() and addCounter() methods.

    @Override
    public ColumnList columns(TridentTuple tuple) {
        ColumnList cols = new ColumnList();
        if(this.columnFields != null){
            // TODO timestamps
            for(String field : this.columnFields){
                cols.addColumn(this.columnFamily, field.getBytes(), toBytes(tuple.getValueByField(field)));
            }
        }
        if(this.counterFields != null){
            for(String field : this.counterFields){
                cols.addCounter(this.columnFamily, field.getBytes(), toLong(tuple.getValueByField(field)));
            }
