BreakIterator

public abstract class BreakIterator
extends Object implements Cloneable

java.lang.Object
↳	android.icu.text.BreakIterator

[icu enhancement] ICU's replacement for BreakIterator. Methods, fields, and other functionality specific to ICU are labeled '[icu]'.

A class that locates boundaries in text. This class defines a protocol for objects that break up a piece of natural-language text according to a set of criteria. Instances or subclasses of BreakIterator can be provided, for example, to break a piece of text into words, sentences, or logical characters according to the conventions of some language or group of languages. We provide five built-in types of BreakIterator:

getTitleInstance() returns a BreakIterator that locates boundaries between title breaks.
getSentenceInstance() returns a BreakIterator that locates boundaries between sentences. This is useful for triple-click selection, for example.
getWordInstance() returns a BreakIterator that locates boundaries between words. This is useful for double-click selection or "find whole words" searches. This type of BreakIterator makes sure there is a boundary position at the beginning and end of each legal word. (Numbers count as words, too.) Whitespace and punctuation are kept separate from real words.
getLineInstance() returns a BreakIterator that locates positions where it is legal for a text editor to wrap lines. This is similar to word breaking, but not the same: punctuation and whitespace are generally kept with words (you don't want a line to start with whitespace, for example), and some special characters can force a position to be considered a line-break position or prevent a position from being a line-break position.
getCharacterInstance() returns a BreakIterator that locates boundaries between logical characters. Because of the structure of the Unicode encoding, a logical character may be stored internally as more than one Unicode code point. (A with an umlaut may be stored as an a followed by a separate combining umlaut character, for example, but the user still thinks of it as one character.) This iterator allows various processes (especially text editors) to treat as characters the units of text that a user would think of as characters, rather than the units of text that the computer sees as "characters".

The text boundary positions are found according to the rules described in Unicode Standard Annex #29, Text Boundaries, and Unicode Standard Annex #14, Line Breaking Properties. These are available at http://www.unicode.org/reports/tr14/ and http://www.unicode.org/reports/tr29/.

BreakIterator's interface follows an "iterator" model (hence the name), meaning it has a concept of a "current position" and methods like first(), last(), next(), and previous() that update the current position. All BreakIterators uphold the following invariants:

The beginning and end of the text are always treated as boundary positions.
The current position of the iterator is always a boundary position (random- access methods move the iterator to the nearest boundary position before or after the specified position, not _to_ the specified position).
DONE is used as a flag to indicate when iteration has stopped. DONE is only returned when the current position is the end of the text and the user calls next(), or when the current position is the beginning of the text and the user calls previous().
Break positions are numbered by the positions of the characters that follow them. Thus, under normal circumstances, the position before the first character is 0, the position after the first character is 1, and the position after the last character is 1 plus the length of the string.
The client can change the position of an iterator, or the text it analyzes, at will, but cannot change the behavior. If the user wants different behavior, he must instantiate a new iterator.

BreakIterator accesses the text it analyzes through a CharacterIterator, which makes it possible to use BreakIterator to analyze text in any text-storage vehicle that provides a CharacterIterator interface. Note: Some types of BreakIterator can take a long time to create, and instances of BreakIterator are not currently cached by the system. For optimal performance, keep instances of BreakIterator around as long as makes sense. For example, when word-wrapping a document, don't create and destroy a new BreakIterator for each line. Create one break iterator for the whole document (or whatever stretch of text you're wrapping) and use it to do the whole job of wrapping the text.

Examples:

Creating and using text boundaries

 public static void main(String args[]) {
      if (args.length == 1) {
          String stringToExamine = args[0];
          //print each word in order
          BreakIterator boundary = BreakIterator.getWordInstance();
          boundary.setText(stringToExamine);
          printEachForward(boundary, stringToExamine);
          //print each sentence in reverse order
          boundary = BreakIterator.getSentenceInstance(Locale.US);
          boundary.setText(stringToExamine);
          printEachBackward(boundary, stringToExamine);
          printFirst(boundary, stringToExamine);
          printLast(boundary, stringToExamine);
      }
 }

Print each element in order

 public static void printEachForward(BreakIterator boundary, String source) {
     int start = boundary.first();
     for (int end = boundary.next();
          end != BreakIterator.DONE;
          start = end, end = boundary.next()) {
          System.out.println(source.substring(start,end));
     }
 }

Print each element in reverse order

 public static void printEachBackward(BreakIterator boundary, String source) {
     int end = boundary.last();
     for (int start = boundary.previous();
          start != BreakIterator.DONE;
          end = start, start = boundary.previous()) {
         System.out.println(source.substring(start,end));
     }
 }

Print first element

 public static void printFirst(BreakIterator boundary, String source) {
     int start = boundary.first();
     int end = boundary.next();
     System.out.println(source.substring(start,end));
 }

Print last element

 public static void printLast(BreakIterator boundary, String source) {
     int end = boundary.last();
     int start = boundary.previous();
     System.out.println(source.substring(start,end));
 }

Print the element at a specified position

 public static void printAt(BreakIterator boundary, int pos, String source) {
     int end = boundary.following(pos);
     int start = boundary.previous();
     System.out.println(source.substring(start,end));
 }

Find the next word

 public static int nextWordStartAfter(int pos, String text) {
     BreakIterator wb = BreakIterator.getWordInstance();
     wb.setText(text);
     int wordStart = wb.following(pos);
     for (;;) {
         int wordLimit = wb.next();
         if (wordLimit == BreakIterator.DONE) {
             return BreakIterator.DONE;
         }
         int wordStatus = wb.getRuleStatus();
         if (wordStatus != BreakIterator.WORD_NONE) {
             return wordStart;
         }
         wordStart = wordLimit;
      }
 }
 
The iterator returned by getWordInstance() is unique in that the break positions it returns don't represent both the start and end of the thing being iterated over. That is, a sentence-break iterator returns breaks that each represent the end of one sentence and the beginning of the next. With the word-break iterator, the characters between two boundaries might be a word, or they might be the punctuation or whitespace between two words. The above code uses getRuleStatus() to identify and ignore boundaries associated with punctuation or other non-word characters.

No guarantees are made about the current position of this iterator when it is returned; it may differ from the BreakIterators current position. If you need to move that position to examine the text, clone this function's return value first.

Returns
`BreakIterator`	An instance of BreakIterator that locates word boundaries.

isBoundary

public boolean isBoundary (int offset)

Return true if the specified position is a boundary position. If the function returns true, the current iteration position is set to the specified position; if the function returns false, the current iteration position is set as though following() had been called.

Parameters
`offset`	`int`: the offset to check.

Returns
`boolean`	True if "offset" is a boundary position.

last

public abstract int last ()

Set the iterator to the last boundary position. This is always the "past-the-end" index of the text this iterator iterates over. For example, if the iterator iterates over a whole string (call it "text"), this function will always return text.length().

Returns
`int`	The character offset of the end of the stretch of text being broken.

public abstract int next ()

Advances the iterator forward one boundary. The current iteration position is updated to point to the next boundary position after the current position, and this is also the value that is returned. If the current position is equal to the value returned by last(), or to DONE, this function returns DONE and sets the current position to DONE.

Returns
`int`	The position of the first boundary position following the iteration position.

public abstract int next (int n)

Move the iterator by the specified number of steps in the text. A positive number moves the iterator forward; a negative number moves the iterator backwards. If this causes the iterator to move off either end of the text, this function returns DONE; otherwise, this function returns the position of the appropriate boundary. Calling this function is equivalent to calling next() or previous() n times.

Parameters
`n`	`int`: The number of boundaries to advance over (if positive, moves forward; if negative, moves backwards).

Returns
`int`	The position of the boundary n boundaries from the current iteration position, or DONE if moving n boundaries causes the iterator to advance off either end of the text.

preceding

public int preceding (int offset)

Sets the iterator's current iteration position to be the last boundary position preceding the specified position. (Whether the specified position is itself a boundary position or not doesn't matter-- this function always moves the iteration position to the last boundary before the specified position.) If the specified position is the starting position, returns DONE.

Parameters
`offset`	`int`: The character position to start searching from.

Returns
`int`	The position of the last boundary position preceding "offset" (whether of not "offset" itself is a boundary position), or DONE if "offset" is the starting offset of the iterator.

public abstract int previous ()

Move the iterator backward one boundary. The current iteration position is updated to point to the last boundary position before the current position, and this is also the value that is returned. If the current position is equal to the value returned by first(), or to DONE, this function returns DONE and sets the current position to DONE.

Returns
`int`	The position of the last boundary position preceding the iteration position.

setText

public void setText (String newText)

Sets the iterator to analyze a new piece of text. The new piece of text is passed in as a String, and the current iteration position is reset to the beginning of the string. (The old text is dropped.)

Parameters
`newText`	`String`: A String containing the text to analyze with this BreakIterator.

setText

public abstract void setText (CharacterIterator newText)

Sets the iterator to analyze a new piece of text. This function resets the current iteration position to the beginning of the text. (The old iterator is dropped.)

Caution: The supplied CharacterIterator is used directly by the BreakIterator, and must not be altered in any way by code outside of the BreakIterator. Doing so will lead to undefined behavior of the BreakIterator.

Parameters
`newText`	`CharacterIterator`: A CharacterIterator referring to the text to analyze with this BreakIterator (the iterator's current position is ignored, but its other state is significant).

setText

public void setText (CharSequence newText)

Sets the iterator to analyze a new piece of text. The new piece of text is passed in as a CharSequence, and the current iteration position is reset to the beginning of the text. (The old text is dropped.)

The text underlying the CharSequence must not be be modified while the BreakIterator holds a references to it. (As could possibly occur with a StringBuilder, for example).

Parameters
`newText`	`CharSequence`: A CharSequence containing the text to analyze with this BreakIterator.
