      Specified by:
      getLimit in interface RequestInfo

    • setLimit

      public void setLimit(Integer limit)
      Sets the maximum number of instances to return in a single response. Used for pagination to control response size and manage memory usage.
      • Default value: Server configuration dependent
      • Example: Set to 50 to get at most 50 instances per request
      • Unlimited results: Set to RequestInfo.UNBOUNDED_LIMIT (-1) for unlimited results (may cause timeout if results are too many)

      limit - Maximum number of instances to return, or RequestInfo.UNBOUNDED_LIMIT for unlimited results

    • getOffset

      Gets the number of instances to skip from the beginning of the result set.
      Specified by:
      getOffset in interface RequestInfo
      Returns:
      the offset value for pagination, or null if not set (defaults to 0)

    • setOffset

      public void setOffset(Integer offset)
      Sets the number of instances to skip from the beginning of the result set. Used for pagination to navigate through large result sets.
      • Default value: 0
      • Example: Set to 10 to skip the first 10 instances (useful for pagination)
      • Query parameter: offset
      Specified by:
      setOffset in interface RequestInfo
      Parameters:
      offset - Number of instances to skip from the beginning

    • includeMeta

      public boolean includeMeta()
      Checks whether to include metadata in the response instance.
      Specified by:
      includeMeta in interface RequestInfo

      true if metadata should be included, false for basic information only

    • setIncludeMeta

      public void setIncludeMeta(boolean includeMeta)
      Sets whether to include metadata in the response instance. Controls whether to include Metadata in the response.
