Method Details

groupByDirectionality

public TextChunk groupByDirectionality(Boolean isLtrDominant)

Splits a TextChunk into N TextChunks, where each chunk is of a single directionality, and then reverse the RTL ones. what we're doing here is *reversing* the Unicode bidi algorithm in the language of that algorithm, each chunk is a (maximal) directional run. We attach whitespace to the beginning of non-RTL

isLtrDominant

public int isLtrDominant()

Overrides:

isLtrDominant in class Rectangle

merge

public TextChunk merge(TextChunk other)

add

public void add(TextElement textElement)

add

public void add(List<TextElement> elements)

getText

public String getText()

Specified by:

getText in interface HasText

Overrides:

getText in class RectangularTextContainer<TextElement>

getText

public String getText(boolean useLineReturns)

Specified by:

getText in interface HasText

Overrides:

getText in class RectangularTextContainer<TextElement>

isSameChar

public boolean isSameChar(Character c)

Returns true if text contained in this TextChunk is the same repeated character

isSameChar

public boolean isSameChar(Character[] c)

splitAt

public TextChunk[] splitAt(int i)

Splits a TextChunk in two, at the position of the i-th TextElement

squeeze

public List<TextChunk> squeeze(Character c,
 int minRunLength)

Removes runs of identical TextElements in this TextChunk For example, if the TextChunk contains this string of characters: "1234xxxxx56xx" and c == 'x' and minRunLength == 4, this method will return a list of TextChunk such that: ["1234", "56xx"]

hashCode

public int hashCode()

Overrides:

hashCode in class Rectangle2D

equals

public boolean equals(Object obj)

Overrides:

equals in class Rectangle2D

allSameChar

public static boolean allSameChar(List<TextChunk> textChunks)

groupByLines

public static List<Line> groupByLines(List<TextChunk> textChunks)
