Java Reference
In-Depth Information
The spider also uses workload managers. Any workload manager used by the spider
must implement the
WorkloadManager
interface. The workload managers manage
the URL list. There are two workload managers provided with the Heaton Research Spi-
der. The
MemoryWorkloadManager
class stores the workload in memory. The
SQLWorkloadManager
class stores the workload in an SQL database.
This chapter introduced internals of the Heaton Research Spider. You also saw how the
MemoryWorkloadManager
was constructed. In the next chapter, you will see how
the
SQLWorkloadManager
class was constructed and how the Heaton Research Spi-
der interacts with an SQL based workload manager.
