Parameters

analysis
Type: OSIsoft.AF.AnalysisAFAnalysis
The AFAnalysis to search for the requested objects.
startTime
Type: SystemObject
An object representing the starting time for the search. 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.
maxCount
Type: SystemInt32
The maximum number of cases to be returned. More than the specified number may be returned if multiple items have the same StartTime for the last case returned.
forward
Type: SystemBoolean
Indicates the direction in time from the start time to proceed when returning cases. If , then cases greater than or equal to the start time (moving forward in time) are returned. If , then cases less than or equal to the start time (moving backward in time) are returned.
nameFilter
Type: SystemString
The case 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 cases must have this category. To not filter by element category, then specify for this parameter.
elemTemplate
Type: OSIsoft.AF.AssetAFElementTemplate
Specify that returned cases must have this template or a template derived from this template. To not filter by element template, then specify for this parameter.

Return Value

Type: AFNamedCollectionListAFCase
Returns the list of AFCase objects which match the search criteria.

Remarks

A case must be saved to the server using ApplyChanges or CheckIn before it will be returned by this find method. This method will return all cases from the specified start time up to the specified maximum count.
