System.Management.Automation.FunctionInfo (class)

A System.Management.Automation.FunctionInfo object provides information about a PowerShell function

FunctionInfo derives from System.Management.Automation.CommandInfo.

In Windows/PowerShell, an instance of a System.Management.Automation.FunctionInfo is returned by the get-command cmdLet when applied on a function:

PS C:\> (get-command mkdir).GetType().FullName

Alternatively, such a class can also be obtained with get-item function:functionName:

PS C:\> function f() {}
PS C:\> $info = get-item function:f
PS C:\> $info.GetType().FullName
System.Management.Automation.FunctionInfo
