ADTSymbolNode

public ADTSymbolNode(@Nullable

                     I symbol)

Method Detail

sift

public ADTNode<S,I,O> sift(SymbolQueryOracle<I,O> oracle,
                           Word<I> prefix)

Description copied from interface: ADTNode

Utility method, that sifts a given word through this ADTNode. If this node is a

• symbol node, the symbol is applied to the system under learning and the corresponding child node (based on the observed output) is returned. If no matching child node is found, a new leaf node is returned instead
• reset node, the system under learning is reset and the provided prefix is reapplied to the system
• leaf node, an exception is thrown

Specified by:

sift in interface ADTNode<S,I,O>

Parameters:

oracle - the oracle used to query the system under learning

prefix - the prefix to be re-applied after encountering a reset node

Returns:

the corresponding child node

getNodeType

public ADTNode.NodeType getNodeType()

Description copied from interface: ADTNode

Returns the node type of the current node.

Specified by:

getNodeType in interface ADTNode<S,I,O>

Returns:

the node type

toString

public String toString()

Overrides:
