|
| public abstract int | current()Return character index of the text boundary that was most recently
returned by next(), previous(), first(), or last()
|
| public abstract int | first()Return the first boundary. The iterator's current position is set
to the first boundary.
|
| public abstract int | following(int offset)Return the first boundary following the specified offset.
The value returned is always greater than the offset or
the value BreakIterator.DONE
|
| public static synchronized java.util.Locale[] | getAvailableLocales()Returns an array of all locales for which the
get*Instance methods of this class can return
localized instances.
The array returned must contain at least a Locale
instance equal to {@link java.util.Locale#US Locale.US}.
//FIX ME - this is a known bug. It should return
//all locales.
return LocaleData.getAvailableLocales("NumberPatterns");

}
}
}

| private static java.util.ResourceBundle | getBundle(java.lang.String baseName, java.util.Locale locale)
return (ResourceBundle) AccessController.doPrivileged(new PrivilegedAction() {
public Object run() {
return ResourceBundle.getBundle(baseName, locale);
}
});
|
| public static java.text.BreakIterator | getCharacterInstance()Create BreakIterator for character-breaks using default locale
Returns an instance of a BreakIterator implementing character breaks.
Character breaks are boundaries of combining character sequences.
return getCharacterInstance(Locale.getDefault());
|
| public static java.text.BreakIterator | getCharacterInstance(java.util.Locale where)Create BreakIterator for character-breaks using specified locale
Returns an instance of a BreakIterator implementing character breaks.
Character breaks are boundaries of combining character sequences.
return getBreakInstance(where,
CHARACTER_INDEX,
"CharacterData",

|
| protected static int | getInt(byte[] buf, int offset)
int num = buf[offset]&0xFF;
for (int i = 1; i < 4; i++) {
num = num<<8 | (buf[offset+i]&0xFF);
}
return num;
|
| public static java.text.BreakIterator | getLineInstance()Create BreakIterator for line-breaks using default locale.
Returns an instance of a BreakIterator implementing line breaks. Line
breaks are logically possible line breaks, actual line breaks are
usually determined based on display width.
LineBreak is useful for word wrapping text.
return getLineInstance(Locale.getDefault());
|
| public static java.text.BreakIterator | getLineInstance(java.util.Locale where)Create BreakIterator for line-breaks using specified locale.
Returns an instance of a BreakIterator implementing line breaks. Line
breaks are logically possible line breaks, actual line breaks are
usually determined based on display width.

| protected static long | getLong(byte[] buf, int offset)

num = num<<8 | (buf[offset+i]&0xFF);
}

|
| public static java.text.BreakIterator | getSentenceInstance()Create BreakIterator for sentence-breaks using default locale
Returns an instance of a BreakIterator implementing sentence breaks.
return getSentenceInstance(Locale.getDefault());
|
| public static java.text.BreakIterator | getSentenceInstance(java.util.Locale where)Create BreakIterator for sentence-breaks using specified locale
Returns an instance of a BreakIterator implementing sentence breaks.
return getBreakInstance(where,
SENTENCE_INDEX,
"SentenceData",
"SentenceDictionary");
|
| protected static short | getShort(byte[] buf, int offset)
short num = (short)(buf[offset]&0xFF);
num = (short)(num<<8 | (buf[offset+1]&0xFF));
return num;
|
| public abstract java.text.CharacterIterator | getText()Get the text being scanned
|
| public static java.text.BreakIterator | getWordInstance()Create BreakIterator for word-breaks using default locale.
Returns an instance of a BreakIterator implementing word breaks.
WordBreak is usefull for word selection (ex. double click)
return getWordInstance(Locale.getDefault());
|
| public static java.text.BreakIterator | getWordInstance(java.util.Locale where)Create BreakIterator for word-breaks using specified locale.
Returns an instance of a BreakIterator implementing word breaks.
WordBreak is usefull for word selection (ex. double click)
return getBreakInstance(where,
WORD_INDEX,
"WordData",
"WordDictionary");
|
| public boolean | isBoundary(int offset)Return true if the specified position is a boundary position.
// NOTE: This implementation probably is wrong for most situations
// because it fails to take into account the possibility that a
// CharacterIterator passed to setText() may not have a begin offset
// of 0. But since the abstract BreakIterator doesn't have that
// knowledge, it assumes the begin offset is 0. If you subclass
// BreakIterator, copy the SimpleTextBoundary implementation of this
// function into your subclass. [This should have been abstract at
// this level, but it's too late to fix that now.]
if (offset == 0)
return true;
else
return following(offset - 1) == offset;
|
| public abstract int | last()Return the last boundary. The iterator's current position is set
to the last boundary.
|
| public abstract int | next(int n)Return the nth boundary from the current boundary
|
| public abstract int | next()Return the boundary following the current boundary.
|
| public int | preceding(int offset)Return the last boundary preceding the specfied offset.
The value returned is always less than the offset or the value
BreakIterator.DONE.
// NOTE: This implementation is here solely because we can't add new
// abstract methods to an existing class. There is almost ALWAYS a
// better, faster way to do this.
int pos = following(offset);
while (pos >= offset && pos != DONE)
pos = previous();
return pos;
|
| public abstract int | previous()Return the boundary preceding the current boundary.
|
| public void | setText(java.lang.String newText)Set a new text string to be scanned. The current scan
position is reset to first().
setText(new StringCharacterIterator(newText));
|
| public abstract void | setText(java.text.CharacterIterator newText)Set a new text for scanning. The current scan
position is reset to first().
