Enum NodeType

java.lang.Object
  java.lang.Enum<NodeType>
      org.deri.iris.evaluation.topdown.oldt.NodeType

All Implemented Interfaces:

Serializable, Comparable<NodeType>

public enum NodeType
extends Enum<NodeType>

Used to classify nodes. LINK A link node which is a special form of a memo node. A link node is not evaluated by resolution, but previously computed answers are used to expand the node. By trying to expand the link node using resolution, the node gets paused. ANSWER A answer node which is a special form of a memo node. A answer node is evaluated by resolution. The answers are stored in the corresponding entry in the memo table. NORMAL A ordinary node (not a memo node).

Method Detail

values

public static final NodeType[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(NodeType c : NodeType.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static NodeType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name
