Field Detail

EXACT_MATCH

public static final int EXACT_MATCH

The automaton has exactly one match for the input sequence.

Constant Field Values

NO_MATCH

public static final int NO_MATCH

The automaton has no match for the input sequence and no sequence in the automaton is a prefix of the input. Note that to check for a general "input does not exist in the automaton" you have to check for both NO_MATCH and AUTOMATON_HAS_PREFIX.

Constant Field Values

AUTOMATON_HAS_PREFIX

public static final int AUTOMATON_HAS_PREFIX

The automaton contains a prefix of the input sequence (but the full sequence does not exist). This translates to: one of the input sequences used to build the automaton is a prefix of the input sequence, but the input sequence contains a non-existent suffix.

_index will contain an index of the first character of the input sequence not present in the dictionary.

Constant Field Values

SEQUENCE_IS_A_PREFIX

public static final int SEQUENCE_IS_A_PREFIX

The sequence is a prefix of at least one sequence in the automaton. _node returns the node from which all sequences with the given prefix start in the automaton.

Constant Field Values

_kind

public int _kind

One of the match types defined in this class.

See Also:

NO_MATCH, EXACT_MATCH, AUTOMATON_HAS_PREFIX, SEQUENCE_IS_A_PREFIX

_index

public int _index

Input sequence's index, interpretation depends on _kind.

_node

public int _node

Automaton node, interpretation depends on the _kind.
