UnlockBranchRequest

public UnlockBranchRequest(Location at,
                           String workspaceName)

Parameters:

at - the location of the node to be unlocked

workspaceName - the name of the workspace containing the node

Throws:

IllegalArgumentException - if the location or workspace name is null

Method Detail

isReadOnly

public boolean isReadOnly()

Return whether this request only reads information.

Specified by:

isReadOnly in class Request

Returns:

true if this request reads information, or false if it requests that the repository content be changed in some way

at

public Location at()

Get the location defining the node that is to be read.

Returns:

the location of the node; never null

inWorkspace

public String inWorkspace()

Get the name of the workspace in which the node exists.

Returns:

the name of the workspace; never null

setActualLocation

public void setActualLocation(Location actualLocation)

Sets the actual and complete location of the node being unlocked. This method must be called when processing the request, and the actual location must have a path.

actualLocation - the actual location of the node before being unlocked

Throws:

IllegalArgumentException - if the either location is null or is missing its path, if the old location is not equal to the current location

IllegalStateException - if the request is frozen

getActualLocation

public Location getActualLocation()

Get the actual location of the node that was unlocked.

Returns:

the actual location of the node being unlocked, or null if the actual location was not set

Specified by:

changes in class ChangeRequest

Parameters:

workspace - the name of the workspace; may not be null
