Constructor Detail

RenameNodeRequest

public RenameNodeRequest(Location at,
                         String workspaceName,
                         Name newName)

Create a request to rename the node at the supplied location.

Parameters:

at - the location of the node to be read

workspaceName - the name of the workspace containing the node

newName - the new name for 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

See Also:

Request.isReadOnly()

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

toName

public Name toName()

Get the new name for the node.

Returns:

the new name; never null

setActualLocations

public void setActualLocations(Location oldLocation,
                               Location newLocation)

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

Parameters:

oldLocation - the actual location of the node before being renamed

newLocation - the actual location of the node after being renamed

Throws:

IllegalArgumentException - if the either location is null or is missing its path, if the old location is not equal to the current location, if the new location does not have the same parent as the old location, or if the new location does not have the same name on last segment as that specified on the request

IllegalStateException - if the request is frozen

getActualLocationBefore

public Location getActualLocationBefore()

Get the actual location of the node before being renamed.

Returns:

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

getActualLocationAfter

public Location getActualLocationAfter()

Get the actual location of the node after being renamed.

Returns:

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

changes

public boolean changes(String workspace,
                       Path path)

Determine if this request changes the branch at the given path.

Specified by:

changes in class ChangeRequest

Parameters:

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

path - the path; may not be null

Returns:

true if this request changes a node under the given path
