Get Indexed Value List VI

Owning Palette: DataFinder Toolkit

Requires: LabVIEW DataFinder Toolkit

Returns a list of strings which contains all indexed values for the specified string property. You can restrict the list of values by setting a prefix. The list is also restricted by the given query. You can determine the number of values you want to receive by wiring the max value count input. You only can use this VI if you search for base properties and optimized custom properties.

 

	DataFinder reference is the reference to the DataFinder to use to execute the search. To connect a registered DataFinder, select the DataFinder from the DataFinder named control.
	property represents a certain property. object type Enumeration for the object type. {File:0, Channel Group:1, Channel:2} property name specifies the property. data type data type of a property indexed by the DataFinder. {String:23, Int32:3,Double:10,Time stamp:30, Unknown:0}
	prefix filters the string list to get a restricted list. Note  Prefixes are ignored when you are connected to a federation. The error out connector then displays a warning.
	query reference is the reference to the query for the search.
	error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.
	max value count (200) specifies the maximum number of values that the DataFinder returns. You can enter values from 1 to 16,384. The default maximum number of indexed values is 200. Note  If you are connected to a federation, DataFinder ignores the max value count connector.
	DataFinder reference out is the reference to the DataFinder that is to be used to execute the search.
	property values specifies the values of the properties.
	query reference out is the reference to the query.
	error out contains error information. This output provides standard error out functionality.
	incomplete values? is TRUE if more indexed values exist than the maximum number of indexed values that are requested. If you want to display more indexed values, you must increase the value of the Max results count parameter.
