Parameters

database

Type: OSIsoft.AFAFDatabase
The AFDatabase to search for the requested objects.

searchMode

Type: OSIsoft.AF.AssetAFSearchMode
Determines how the startTime and endTime parameters are treated when searching for event frame objects 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 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. When the specified startTime is earlier than the endTime, the items in the resulting list will be indexed in time ascending direction. If the startTime is more recent than the endTime, the items in the resulting list will be indexed in time descending direction. 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 transfer 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'.

sourceFilter

Type: OSIsoft.AF.AssetAFBaseElement
Specify that the transfer of the returned attributes must have this Source. To not filter by source, then specify for this parameter.

destinationFilter

Type: OSIsoft.AF.AssetAFBaseElement
Specify that the transfer of the returned attributes must have this Destination. To not filter by destination, then specify for this parameter.

elemCategory

Type: OSIsoft.AFAFCategory
Specify that the owner of the returned attributes must have this category. To not filter by element category, then specify for this parameter.

elemTemplate

Type: OSIsoft.AF.AssetAFElementTemplate
Specify that the owner of the returned attributes must have this template or a template derived from this template. To not filter by element template, then specify for this parameter.

attrNameFilter

Type: SystemString

The attribute 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'.

attrCategory

Type: OSIsoft.AFAFCategory
Specify that returned attributes must have this category. To not filter by attribute category, then specify for this parameter.

attrType

Type: SystemTypeCode
Specify that returned attributes must have this Type. To not filter by attribute type, then specify Empty. If Object is specified, then attributes which do not have a type defined (displayed as Anything in PI System Explorer), will be returned, as well as types which cannot be described by a simpler type code, such as enumeration values, arrays, files, and references to other AF objects.

sortField

Type: OSIsoft.AFAFSortField
The field or property of the object used to sort the returned collection.

sortOrder

Type: OSIsoft.AFAFSortOrder
The order that the returned collection is sorted.

maxCount

Type: SystemInt32
The maximum number of objects to be returned.

Return Value

AFSDK
