net.java.sen.dictionary.Sentence

public class Sentence
extends Object

A Sentence represents a character array to be morphologically analysed. It supports breaking ignore spans, which prevent certain characters from being considered for tokenisation, and reading constraints which restrict the returned morphemes at a certain position to those with the given reading.

Modifier and Type	Method and Description
char[]	getCharacters() Returns the underlying characters of this Sentence
Reading	getReadingConstraint(int position) Gets the reading constraint at the given position, if any
SentenceIterator	iterator() Returns a SentenceIterator that obeys the defined breaking ignore spans, reading constraints, and skips space characters

Constructor Detail

Sentence

public Sentence(char[] characters)

Creates a sentence with the given characters

Parameters:

characters - The sentence's characters

Sentence

public Sentence(String text)

Creates a sentence with the given string

Parameters:

text - The string containing the sentence's characters

Method Detail

setBreakingIgnoreSpan

public void setBreakingIgnoreSpan(int position,
                         short length)

Sets a breaking ignore span. length characters starting at position will be ignored during iteration; no iterated subsequence of characters will cross the ignored span.

Parameters:

position - The position of the ignore span to set

length - The length of the ignore span to set

setReadingConstraint

public void setReadingConstraint(Reading constraint)

Sets a reading constraint on the Sentence starting at position; any existing constraints that overlap the new constraint will be removed.

Parameters:

constraint - The constraint to set

getReadingConstraint

public Reading getReadingConstraint(int position)

Gets the reading constraint at the given position, if any

Parameters:

position - The position to get the constraint at

Returns:

The constraint if present, or null

removeReadingConstraint

public void removeReadingConstraint(int position)

Removes the reading constraint at the given position, if any

Parameters:

position - The position to remove the constraint from

iterator

public SentenceIterator iterator()

Returns a SentenceIterator that obeys the defined breaking ignore spans, reading constraints, and skips space characters

Returns:

The iterator

unconstrainedIterator

public SentenceIterator unconstrainedIterator(int position)

Returns a SentenceIterator that obeys the defined breaking ignore spans, skips space characters, but ignores reading constraints

Parameters:

position - The position to start iterating from

Returns:

The iterator

getCharacters

public char[] getCharacters()

Returns the underlying characters of this Sentence

Returns:

The underlying characters
