public interface NodeFactory extends Serializable
Node
objects on demand, to encapsulate specified variables.
Factory objects can choose to return implementations of the Node
interface which are memory-optimized for
storing only the given variables, potentially further optimized based on variable values.Modifier and Type | Method and Description |

Node createNode(CharSequence edgeCharacters, Object value, List<Node> childNodes, boolean isRoot)
Node
object which encapsulates the arguments supplied, optionally returning implementations
of the Node
interface which are memory-optimized for storing only the supplied combination of variables,
potentially further optimized based on variable values.edgeCharacters
- Provides edge characters to be stored in the node. This is never null. In the case of
(re-)constructing the root node, this will contain zero characters, otherwise will always contain one or more
charactersvalue
- An arbitrary object to associate with the node. This can be null, but it will not be null if
dealing with a leaf node (when childNodes will be empty)childNodes
- A list of child nodes to store in the node. This will never be null, but may be empty when
building a leaf nodeisRoot
- Indicates if this will be the root node, in which case edge characters will be non-null but empty,
value will be null, and child nodes will be non-null but may be emptyNode
