  • Method Details

    • getCacheKey

      Object getCacheKey()
      Returns a key that becomes part of the key for caching the result of the SQL query. So SqlConstraint instances that produce the same SQL resultset must return equal keys in terms of equal() and hashCode().
      Returns:
      valid key or null to prevent the result from being cached
