rver_name; a GUID, in the form 1234-5678-9807, or an
SPSite object.
Required? false
Position? Named
Default value
Accept pipeline input? True
Accept wildcard characters? false
From this snippet, you can see that the Get-SPWeb cmdlet can take an
SPAssignmentCollection object (which is discussed in Chapter 3) via the pipe-
line, but you cannot pass the Identity parameter via the pipeline. Also notice
that you can pass in an SPSitePipeBind object via the pipeline. So what is a
PipeBind object?
PipeBind Objects
As you look through the various SharePoint cmdlets, you will notice that most
of them have one or more parameters that take a special object type called a
PipeBind object. Examine again the  rst parameter from the help text of the
Get-SPWeb cmdlet shown earlier. Following is the relevant piece:
-Identity <SPWebPipeBind>
Specifies the name or full or partial URL of the subsite.
If you use a relative path, you must specify the Site
parameter.
A valid URL in the form http://server_name or a relative
path in the form of /SubSites/MySubSite.
Required? false
Position? 1
Default value
Accept pipeline input? False
Accept wildcard characters? false
Within SharePoint, many objects (such as the SPWeb and SPSite objects) can be
represented di erently. An SPSite object, for example, can be represented using
either a URL, a GUID (unique identi er), or an actual
SPSite object. PipeBind
objects allow you to use either of these representations for the parameter value.
WARNING One thing to note is that the name is a bit misleading. Not all PipeBind
parameters can accept input from the pipeline.
