Parameters

system

Type: OSIsoft.AFPISystem
The PISystem to search for the desired objects.

objectIds

Type: System.Collections.GenericIListAFAttributeValueQueryID
The list of AFAttributeValueQueryID to be found. If , then this method does nothing.

queryDate (Optional)

Type: SystemObject
The query date used to load the objects. Specify or AFTime.MaxValue for most recent versions of the objects. 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 AFTime.Now.

useSandbox (Optional)

Type: SystemBoolean
Specify whether to search for values in the sandbox. If set to false, only values in permanent storage will be returned.

userIdentity (Optional)

Type: System.Security.PrincipalWindowsIdentity
The WindowsIdentity of the user for the security rights to be checked. Only domain accounts or local accounts on the PI AF Server are supported by this method.

Return Value

AFSDK
