Constructor Detail

TildeNode

public TildeNode(jason.asSyntax.Term label,
                 jason.asSyntax.ListTerm examples)

Initializes an inner node.

Parameters:

label - The label of the current node. Can be either a literal or a conjunction of literals.

examples - The list of examples belonging to this node.

TildeNode

public TildeNode(jason.asSyntax.Term label)

Initializes an inner node.

Parameters:

label - The label of the current node. Can be either a literal or a conjunction of literals.

Method Detail

isInner

public boolean isInner()

Check if this node is an inner node.

Returns:

true if this node is an inner node, false otherwise.

isLeaf

public boolean isLeaf()
