implements java.lang.Cloneable

The QTextBoundaryFinder class provides a way of finding Unicode text boundaries in a string. QTextBoundaryFinder allows to find Unicode text boundaries in a string, similar to the Unicode text boundary specification (see http://www.unicode.org/reports/tr29/tr29-11.html).

QTextBoundaryFinder can operate on a QString in four possible modes depending on the value of `BoundaryType`.

Units of Unicode characters that make up what the user thinks of as a character or basic unit of the language are here called Grapheme clusters. The two unicode characters 'A' + diaeresis do for example form one grapheme cluster as the user thinks of them as one character, yet it is in this case represented by two unicode code points.

Word boundaries are there to locate the start and end of what a language considers to be a word.

Line break boundaries give possible places where a line break might happen and sentence boundaries will show the beginning and end of whole sentences.

Constructor Detail

### QTextBoundaryFinder

    public QTextBoundaryFinder()

  Constructs an invalid QTextBoundaryFinder object.

### QTextBoundaryFinder

    public QTextBoundaryFinder(QTextBoundaryFinder.BoundaryType type,
                               java.lang.String string)

  Creates a QTextBoundaryFinder object of `type` operating on `string`.

### QTextBoundaryFinder

    public QTextBoundaryFinder(QTextBoundaryFinder other)

  Copies the QTextBoundaryFinder object, `other`.

Method Detail

### boundaryReasons

    public final QTextBoundaryFinder.BoundaryReasons boundaryReasons()

  Returns the reasons for the boundary finder to have chosen the current position as a boundary.

### isAtBoundary

    public final boolean isAtBoundary()

  Returns true if the object's `position()` is currently at a valid text boundary.

### isValid

    public final boolean isValid()

  Returns true if the text boundary finder is valid; otherwise returns false. A default QTextBoundaryFinder is invalid.

### position

    public final int position()

  Returns the current position of the QTextBoundaryFinder.

See also:
  `setPosition()`.

### setPosition

    public final void setPosition(int position)

  Sets the current position of the QTextBoundaryFinder to `position`. If `position` is out of bounds it will get bound to the valid positions.

See also:
  `position()`.

### string

    public final java.lang.String string()

  Returns the string the QTextBoundaryFinder object operates on.

### toEnd

    public final void toEnd()

  Moves the finder to the end of the string. This is equivalent to setPosition(string.length()).

See also:
  `setPosition()`, and `position()`.

### toNextBoundary

    public final int toNextBoundary()

  Moves the QTextBoundaryFinder to the next boundary position and returns that position.

  Returns -1 is there is no next boundary.

### toPreviousBoundary

    public final int toPreviousBoundary()

  Moves the QTextBoundaryFinder to the previous boundary position and returns that position.

  Returns -1 is there is no previous boundary.

### toStart

    public final void toStart()

  Moves the finder to the start of the string. This is equivalent to setPosition(0).

See also:
  `setPosition()`, and `position()`.

### type

    public final QTextBoundaryFinder.BoundaryType type()

  Returns the type of the QTextBoundaryFinder.

### clone

    public QTextBoundaryFinder clone()

  This method is reimplemented for internal reasons

  Overrides:
    `clone` in class `java.lang.Object`
