Summary: Used to view data stored on the space (classes and number of instances).

Overview

The Classes view displays a list of classes stored in the space, and their instance count. You can view the class instances content using the Query view. Clear the class instances or completely delete the class and all its instances from the space.

Details are displayed for each class – i.e., attributes and their properties (names, types, indexed), whether the class is FIFO enabled, whether the class is partial-replication enabled, a list of super classes, codebase, etc. These properties appear at the bottom of the Service View panel on the right when the class is selected.

Classes List

The Classes List is located at the top of the Service View panel on the right. It displays the classes stored in the space, and their current instance and template count (how many classes and how many templates currently exist in the space). Class meta data is introduced to the space after the first write operation of one of its instances or after calling the snapshot method.

In GigaSpaces 6.5 and onwards, the Classes List doesn't display any classes or objects for persistent spaces working in LRU mode. If you are working with such a space and want to turn on this option, from the top menu, select View > Display Persistent LRU Space Metrics (toggle option).

The following buttons appear at the bottom of the Classes List (right clicking a class row also displays these options):

  • Query – opens the Query view with the selected class content in the result table, where each Entry is displayed in a separate row.
  • Delete – removes a class and all its instances from the space. This option removes all existing templates and class meta data from the space.
  • Clear – clears class instances from the space, while keeping the class meta data in the space.

Class Info

The Class Info panel at the bottom of the Service View displays the following:

  • Public Entry class attributes, their types and indexes
  • The name of the class routing field ( new in GigaSpaces version 6.5 and onwards)
  • List of super classes
  • Codebase
  • Indication whether the class is FIFO enabled.
  • Indication whether the class is partial-replication enabled
  • Indication whether the class uses extended indexing
  • Object Format – displays whether the object is an Entry or a POJO.

Templates Info

The Templates Info tab at the bottom of the Service View displays the number of notification templates that exist in the space; and a table of all the notification templates, specifying when the template is supposed to expire, the UID of the object the template is registered for, and if the template indicates FIFO mode.

Refresh Options

You can choose to refresh the Classes List periodically. Select the desired refresh rate from the drop-down menu. To stop automatically refreshing the Classes List, click the Stop button. The refresh activity impacts server performance, so when running benchmarks you might want to stop auto-refresh activity (by clicking the Stop button). When auto-refresh is running, a green blinking dot is displayed on the right side of the screen.
