<br />
==Methods==<br />
<br />
===GetHelp===<br />
The '''GetHelp''' method is called when the ''-Help'' option is specified for an operation:<br />
<br />
LabVIEWCLI -OperationName <name> -Help<br />
<br />
Each operation must override the GetHelp method to provide custom help text. The method has a single return value for the help text.<br />
<br />
{| class="wikitable" style="text-align: center;"<br />
!DataType<br />
!Description<br />
|-<br />
|{{Terminal|type=indicator|string}}<br />
|style="text-align: left;"|Help text. This is displayed on the command line when using the ''-Help'' flag.<br />
|}<br />
<br />
===RunOperation===<br />
The '''RunOperation''' method executes when an operation is called:<br />
<br />
LabVIEWCLI -OperationName <name> [<arg>...]<br />
<br />
Each operation must override the RunOperation method to provide custom behavior. The method receives the list of arguments and returns the return code and output text to display on the command line. A return code of zero indicates success.<br />
<br />
{| class="wikitable" style="text-align: center;"<br />
!DataType<br />
!Description<br />
|-<br />
|{{Terminal|type=control|1d array of string}}<br />
|style="text-align: left;"|List of arguments and values in the order they are specified on the command line. For example, "-arg1 99" is provided as ["-arg2", "99"].<br />
|-<br />
|{{Terminal|type=indicator|i32}}<br />
|style="text-align: left;"|Return code. 0 indicates success.<br />
|-<br />
|{{Terminal|type=indicator|string}}<br />
|style="text-align: left;"|Output text to display on the command line.<br />
|}<br />
<br />
===Read Logger===<br />
The '''Read Logger''' method provides access to the [[Logger]] instance of the CoreOperation class. Operations can use this method to access the logger to put additional output on the command line.<br />
