Parameters

searchMode
Type: OSIsoft.AF.AssetAFSearchMode
Determines how the startTime and endTime parameters are treated when searching for event frames to be included in the returned collection.
startTime
Type: SystemObject
An object representing the earliest starting time for the event frames to be returned. The startTime must be less than or equal to the endTime. The value may be an AFTime, DateTime, PITime, String, or numeric. A DateTime (or a DATE will be treated as UTC time if its Kind property is set to Unspecified. Because DATE values from COM or VB6 clients are marshalled as Unspecified, these client applications must convert to UTC prior to marshalling. An integer numeric represents the number of ticks (100-nanosecond intervals) since January 1, 0001. A floating point numeric represents the number of seconds since January 1, 1970 UTC. A String is interpreted as local time, unless it contains a time zone indicator such as a trailing "Z" or "GMT". Strings will be interpreted with the AFTime.Parse Overload methods so that relative formats with intervals ("*", "T+3h", etc.) are also supported. Relative time intervals are based on the object's QueryDate.
endTime
Type: SystemObject
An object representing the latest ending time for the event frames to be returned. The endTime must be greater than or equal to the startTime. The value may be an AFTime, DateTime, PITime, String, or numeric. A DateTime (or a DATE will be treated as UTC time if its Kind property is set to Unspecified. Because DATE values from COM or VB6 clients are marshalled as Unspecified, these client applications must convert to UTC prior to marshalling. An integer numeric represents the number of ticks (100-nanosecond intervals) since January 1, 0001. A floating point numeric represents the number of seconds since January 1, 1970 UTC. A String is interpreted as local time, unless it contains a time zone indicator such as a trailing "Z" or "GMT". Strings will be interpreted with the AFTime.Parse Overload methods so that relative formats with intervals ("*", "T+3h", etc.) are also supported. Relative time intervals are based on the object's QueryDate.
nameFilter
Type: SystemString
The event frame name filter string used for finding objects.

The query string (or match pattern) can include regular characters and wildcard characters. Regular characters must match exactly the characters specified in the query string. Wildcard characters can be matched with arbitrary fragments of the query string. Wildcard characters can be escaped using the single backslash (\) character. Use a double backslash (\\) to match a single backslash. The syntax of the query string has the following rules:

  • If or empty string, then everything will be matched.
  • If no wildcards, then an exact match on the query string is performed.
  • Wildcard * can be placed anywhere in the query string and matches zero or more characters.
  • Wildcard ? can be placed anywhere in the query string and matches exactly one character.
  • One character in a set of characters are matched by placing them within [ ]. For example, a[bc] would match 'ab' or 'ac', but it would not match 'ad' or 'abd'.
  • One character in a set of characters are not matched by placing them within [! ]. For example, a[!bc] would match 'ad', but it would not match 'ab', 'ac', or 'abd'.
  • A character in a range of characters from first to last are matched using the following syntax: [first - last]. For example, a[a-c] would match 'aa', 'ab', or 'ac', but it would not match 'ad' or 'abc'.

elemCategory
Type: OSIsoft.AFAFCategory
Specify that returned event frames must have this category. To not filter by element category, then specify for this parameter.
elemTemplate
Type: OSIsoft.AF.AssetAFElementTemplate
Specify that returned event frames must have this template or a template derived from this template. To not filter by element template, then specify for this parameter.
sortField
Type: OSIsoft.AFAFSortField
The field or property of the object used to sort the returned collection. This value should not be changed between calls when attempting to get the next page of items.
sortOrder
Type: OSIsoft.AFAFSortOrder
The order that the returned collection is sorted. This value should not be changed between calls when attempting to get the next page of items.
startIndex
Type: SystemInt32
The starting index (zero based) of the items to be returned.
maxCount
Type: SystemInt32
The maximum number of objects to be returned per call (the page size).

Return Value

Type: AFNamedCollectionListAFEventFrame
Returns a collection containing the specified page of AFEventFrame objects which reference this element within the specified time range.
