                                 Name propertyName)

  Create a request to remove a named property from the node at the supplied location.

  Parameters:
    `from` - the location of the node to be read
    `workspaceName` - the name of the workspace containing the node
    `propertyName` - the name of the property to be removed
  Throws:
    `IllegalArgumentException` - if the location, workspace name, or property 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()`

### from

    public Location from()

  Get the location defining the node from which the property is to be removed.

  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

### propertyName

    public Name propertyName()

  Returns:
    the property name; never null

### setActualLocationOfNode

    public void setActualLocationOfNode(Location actual)

  Sets the actual and complete location of the node being updated. 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 updated, or null if the `current location` should be used
  Throws:
    `IllegalArgumentException` - if the actual location is null or does not have a path.

### getActualLocationOfNode

    public Location getActualLocationOfNode()

  Get the actual location of the node that was updated.

  Returns:
    the actual location, or null if the actual location was not set

### changes

    public boolean changes(String workspace,
