Example 32 with StringByteIterator

use of com.yahoo.ycsb.StringByteIterator in project YCSB by brianfrankcooper.

the class SolrClient method scan.

/**
   * Perform a range scan for a set of records in the database. Each field/value pair from the
   * result will be stored in a HashMap.
   *
   * @param table
   *          The name of the table
   * @param startkey
   *          The record key of the first record to read.
   * @param recordcount
   *          The number of records to read
   * @param fields
   *          The list of fields to read, or null for all of them
   * @param result
   *          A Vector of HashMaps, where each HashMap is a set field/value pairs for one record
   * @return Zero on success, a non-zero error code on error. See this class's description for a
   *         discussion of error codes.
