Constructor Detail

ShowResourceObjectsRequest

public ShowResourceObjectsRequest()

Constructs a ShowResourceObjectsRequest object with default parameters.

ShowResourceObjectsRequest

public ShowResourceObjectsRequest(Map<String,String> options)

Constructs a ShowResourceObjectsRequest object with the specified parameters.

Parameters:

options - Optional parameters.

• TIERS: Comma-separated list of tiers to query, leave blank for all tiers.
• EXPRESSION: An expression to filter the returned objects. Expression is limited to the following operators: =,!=,<,<=,>,>=,+,-,*,AND,OR,LIKE. For details see Expressions. To use a more complex expression, query the ki_catalog.ki_tiered_objects table directly.
• ORDER_BY: Single column to be sorted by as well as the sort direction, e.g., 'size asc'. Supported values:
  • SIZE
  • ID
  • PRIORITY
  • TIER
  • EVICTABLE
  • OWNER_RESOURCE_GROUP
• LIMIT: An integer indicating the maximum number of results to be returned, per rank, or (-1) to indicate that the maximum number of results allowed by the server should be returned. The number of records returned will never exceed the server's own limit, defined by the max_get_records_size parameter in the server configuration. The default value is '100'.
• TABLE_NAMES: Comma-separated list of tables to restrict the results to. Use '*' to show all tables.

The default value is an empty Map.
