  java.text.WordBreakTable

final class WordBreakTable

extends Object

This class implements a state transition table. After each transition, using the get method, the new state is returned along with information about the state change (ex. was it a "marked" transition"). This class is internal only.

Field Summary

private int	cols
private byte[]	data
private static int	END_STATE
(package private) static byte	INDEX_MASK
private static int	INITIAL_STATE
(package private) static byte	MARK_MASK

Constructor Summary

WordBreakTable(int cols, byte[] data)
Construct a table using existing data.

Method Summary

int	get(int oldState, int input) Get the resulting state moving from oldState accepting input
int	initialState() Get the start state
boolean	isEndState(int state) Check is a state is the end state
boolean	isMarkState(int state) Checks to see if the transition into the specified state was "marked"

Constructor Detail

WordBreakTable

public WordBreakTable(int cols,
                      byte[] data)

Construct a table using existing data. See SentenceBreakBoundary and the other SimpleTextBoundary subclasses for examples.

Parameters:

cols - number of columns in the table

data - an encoded byte array containing state and transition data

Method Detail

get

public int get(int oldState,
               int input)

Get the resulting state moving from oldState accepting input

Parameters:

oldState - current state

input - input

Returns:

int resulting state and transition data

isMarkState

public boolean isMarkState(int state)

Checks to see if the transition into the specified state was "marked"

Parameters:

state - the state as returned by get, initialState, or endState

Returns:

true if transition into state was marked.

isEndState

public boolean isEndState(int state)

Check is a state is the end state

Parameters:

state - the state to check

Returns:

true if state is an end state

initialState

public int initialState()

Get the start state

Returns:

the initial state
