AreaIteration/AreaIteration.psm1

<#
.SYNOPSIS
    Gets one or more Areas ("Area Paths") from a given Team Project.

.PARAMETER Area
    
    Specifies the name, URI or path of an Area. Wildcards are permitted. If omitted, all Areas in the given Team Project are returned.

    To supply a path, use a backslash ("\") between the path segments. Leading and trailing backslashes are optional.

    When supplying a URI, use URIs in the form of "vstfs:///Classification/Node/<GUID>" (where <GUID> is the unique identifier of the given node)


.PARAMETER Project
    
    Specifies either the name of the Team Project or a previously initialized Microsoft.TeamFoundation.WorkItemTracking.Client.Project object to connect to. If omitted, it defaults to the connection opened by Connect-TfsTeamProject (if any).

    For more details, see the Get-TfsTeamProject cmdlet.


.PARAMETER Collection
    
    Specifies either a URL/name of the Team Project Collection to connect to, or a previously initialized TfsTeamProjectCollection object.

    When using a URL, it must be fully qualified. The format of this string is as follows:

    http[s]://<ComputerName>:<Port>/[<TFS-vDir>/]<CollectionName>

    Valid values for the Transport segment of the URI are HTTP and HTTPS. If you specify a connection URI with a Transport segment, but do not specify a port, the session is created with standards ports: 80 for HTTP and 443 for HTTPS.

    To connect to a Team Project Collection by using its name, a TfsConfigurationServer object must be supplied either via -Server argument or via a previous call to the Connect-TfsConfigurationServer cmdlet.

    For more details, see the Get-TfsTeamProjectCollection cmdlet.

<#
.SYNOPSIS
    Changes the value of a property of an Iteration.

.PARAMETER Iteration
    
    Specifies the name, URI or path of an Iteration. Wildcards are permitted. If omitted, all Iterations in the given Team Project are returned.

    To supply a path, use a backslash ("\") between the path segments. Leading and trailing backslashes are optional.

    When supplying a URI, use URIs in the form of "vstfs:///Classification/Node/<GUID>" (where <GUID> is the unique identifier of the given node)


.PARAMETER NewName
    Specifies the new name of the iteration. Enter only a name, not a path and name. If you enter a path that is different from the path that is specified in the Iteration parameter, Rename-TfsIteration generates an error. To rename and move an item, use the Move-TfsIteration cmdlet.

.PARAMETER MoveBy
    Reorders an iteration by moving it either up or down inside its parent. A positive value moves an iteration down, whereas a negative one moves it up.

.PARAMETER StartDate
    Sets the start date of the iteration. To clear the start date, set it to $null. Note that when clearing a date, both must be cleared at the same time (i.e. setting both StartDate and FinishDate to $null)

.PARAMETER FinishDate
    Sets the finish date of the iteration. To clear the finish date, set it to $null. Note that when clearing a date, both must be cleared at the same time (i.e. setting both StartDate and FinishDate to $null)

.PARAMETER Project
    
    Specifies either the name of the Team Project or a previously initialized Microsoft.TeamFoundation.WorkItemTracking.Client.Project object to connect to. If omitted, it defaults to the connection opened by Connect-TfsTeamProject (if any).

    For more details, see the Get-TfsTeamProject cmdlet.


.PARAMETER Collection
    
    Specifies either a URL/name of the Team Project Collection to connect to, or a previously initialized TfsTeamProjectCollection object.

    When using a URL, it must be fully qualified. The format of this string is as follows:

    http[s]://<ComputerName>:<Port>/[<TFS-vDir>/]<CollectionName>

    Valid values for the Transport segment of the URI are HTTP and HTTPS. If you specify a connection URI with a Transport segment, but do not specify a port, the session is created with standards ports: 80 for HTTP and 443 for HTTPS.

    To connect to a Team Project Collection by using its name, a TfsConfigurationServer object must be supplied either via -Server argument or via a previous call to the Connect-TfsConfigurationServer cmdlet.

    For more details, see the Get-TfsTeamProjectCollection cmdlet.
