Parameters

database
Type: OSIsoft.AFAFDatabase
The AFDatabase to search for the requested objects.
startTime
Type: SystemObject
An object representing the starting time to begin the search. The search may compare against either the StartTime or EndTime of the transfer based on the searchMode parameter. 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 transfers to be returned. More than the specified number may be returned if multiple items have the same StartTime for the last transfer returned.
searchMode
Type: OSIsoft.AF.EventFrameAFEventFrameSearchMode
Indicates the direction in time from the StartTime or EndTime to proceed when returning transfers.
nameFilter
Type: SystemString
If not an empty string, only transfers which match the supplied filter on their name property will be returned.
sourceFilter
Type: OSIsoft.AF.AssetAFBaseElement
If not , only AFTransfers with the specified Source will be returned.
destinationFilter
Type: OSIsoft.AF.AssetAFBaseElement
If not , only AFTransfers with the specified Destination will be returned.
elemCategory
Type: OSIsoft.AFAFCategory
Specify that returned transfers must have this category. To not filter by element category, then specify for this parameter.
elemTemplate
Type: OSIsoft.AF.AssetAFElementTemplate
Specify that returned transfers 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: AFNamedCollectionListAFTransfer
Returns the list of AFTransfer objects which match the search criteria.

Remarks

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

Important note Important
Consider using the new AFTransferSearch class for finding transfers instead of using this method.
