`PathNode` | `copyNode(ExecutionContext context, PathNode original, PathWorkspace originalWorkspace, PathNode newParent, Name desiredName, boolean recursive)` Copy the subgraph given by the original node and place the new copy under the supplied new parent.
`PathNode` | `createNode(ExecutionContext context, PathNode parentNode, Name name, Map<Name,Property> properties, NodeConflictBehavior conflictBehavior)` Create a new node with the supplied name, as a child of the supplied parent.
`PathNode` | `createNode(ExecutionContext context, String pathToNewNode, Map<Name,Property> properties, NodeConflictBehavior conflictBehavior)` Create a node at the supplied path.
`PathNode` | `moveNode(ExecutionContext context, PathNode node, Name desiredNewName, WritablePathWorkspace originalWorkspace, PathNode newParent, PathNode beforeNode)` Move the supplied node to the new parent within this workspace.
`boolean` | `removeNode(ExecutionContext context, Path nodePath)` Removes the node at the given path

Method Detail

### createNode

    PathNode createNode(ExecutionContext context,
                        String pathToNewNode,
                        Map<Name,Property> properties,
                        NodeConflictBehavior conflictBehavior)

  Create a node at the supplied path. The parent of the new node must already exist.

  Parameters:
    `context` - the environment; may not be null
    `pathToNewNode` - the path to the new node; may not be null
    `properties` - the properties for the new node
    `conflictBehavior` - the expected behavior if an equivalently-named child already exists at the location
  Returns:
    the new node (or root if the path specified the root)

### createNode

    PathNode createNode(ExecutionContext context,
                        PathNode parentNode,
                        Name name,
                        Map<Name,Property> properties,
                        NodeConflictBehavior conflictBehavior)

  Create a new node with the supplied name, as a child of the supplied parent.

  Parameters:
    `context` - the execution context
    `parentNode` - the parent node; may not be null
    `name` - the name; may not be null
    `properties` - the properties for the new node
    `conflictBehavior` - the expected behavior if an equivalently-named child already exists at the location
  Returns:
    the new node

### moveNode

    PathNode moveNode(ExecutionContext context,
                      PathNode node,
                      Name desiredNewName,
                      WritablePathWorkspace originalWorkspace,
                      PathNode newParent,
                      PathNode beforeNode)

  Move the supplied node to the new parent within this workspace. This method automatically removes the node from its existing parent, and also correctly adjusts the `index` to be correct in the new parent.

  Parameters:
    `context` -
    `node` - the node to be moved; may not be the workspace root node
    `desiredNewName` - the new name for the node, if it is to be changed; may be null
    `originalWorkspace` - the workspace containing the node to be moved
    `newParent` - the new parent; may not be the workspace root node
    `beforeNode` - the node before which this new node should be placed
  Returns:
    a new copy of `node` that reflects the new location

### copyNode

    PathNode copyNode(ExecutionContext context,
                      PathNode original,
                      PathWorkspace originalWorkspace,
                      PathNode newParent,
                      Name desiredName,
                      boolean recursive)

  Copy the subgraph given by the original node and place the new copy under the supplied new parent. Note that internal references between nodes within the original subgraph must be reflected as internal nodes within the new subgraph.

  Parameters:
    `context` - the context; may not be null
    `original` - the node to be copied; may not be null
    `originalWorkspace` - the workspace containing the original parent node; may not be null
    `newParent` - the parent where the copy is to be placed; may not be null
    `desiredName` - the desired name for the node; if null, the name will be obtained from the original node
    `recursive` - true if the copy should be recursive
  Returns:
    the new node, which is the top of the new subgraph

### removeNode

    boolean removeNode(ExecutionContext context,
                       Path nodePath)

  Removes the node at the given path

  Parameters:
    `context` - the context; may not be null
    `nodePath` - the path of the node to be removed
  Returns:
    true if the node existed (and was removed); false otherwise

### setProperties

    PathNode setProperties(ExecutionContext context,
                           Path nodePath,
                           Map<Name,Property> properties)

  Sets the given properties in a single operation, overwriting any previous properties for the same name. This bulk mutator should be used when multiple properties are being set in order to allow underlying implementations to optimize their access to their respective persistent storage mechanism.

  Parameters:
    `context` - the context; may not be null
    `nodePath` - the path to the node on which the properties should be set
    `properties` - the properties to set
  Returns:
    this map node

### removeProperties

    PathNode removeProperties(ExecutionContext context,
                              Path nodePath,
                              Iterable<Name> propertyNames)

  Removes the properties with the given names

  Parameters:
    `context` - the context; may not be null
    `nodePath` - the path to the node from which the properties should be removed
    `propertyNames` - the name of the properties to remove
  Returns:
    this map node
