Constructor Detail

### DeleteBranchRequest

    public DeleteBranchRequest(Location at,
                               String workspaceName)

  Create a request to delete a branch.

  Parameters:
    `at` - the location of the top node in the existing branch that is to be deleted
    `workspaceName` - the name of the workspace containing the parent
  Throws:
    `IllegalArgumentException` - if the location or workspace name is null

Method Detail

### at

    public Location at()

  Get the location defining the top of the branch to be deleted

  Returns:
    the location of the branch; never null

### inWorkspace

    public String inWorkspace()

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

  Returns:
    the name of the workspace; never null

### 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()`

### setActualLocationOfNode

    public void setActualLocationOfNode(Location actual)

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

  Parameters:
    `actual` - the actual location of the node being deleted, or null if the `current location` should be used
  Throws:
    `IllegalArgumentException` - if the actual location is null or does not have a path.
    `IllegalStateException` - if the request is frozen

### getActualLocationOfNode

    public Location getActualLocationOfNode()

  Get the actual location of the node that was deleted.

  Returns:
    the actual location, 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.

    `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
