• Method Detail

  • getBlockEndLines

    public int[] getBlockEndLines()

  • getBlockIndices

    public int[] getBlockIndices()

  • getNumberOfBlocks

    public int getNumberOfBlocks()

  • getLineCount

    public int getLineCount()

    Description copied from class: Layout
    Return the number of lines of text in this layout.

    Specified by:

    getLineCount in class Layout

  • getLineTop

    public int getLineTop(int line)

    Description copied from class: Layout
    Return the vertical position of the top of the specified line (0…getLineCount()). If the specified line is equal to the line count, returns the bottom of the last line.

    Specified by:

    getLineTop in class Layout

  • getLineDescent

    public int getLineDescent(int line)

    Description copied from class: Layout
    Return the descent of the specified line(0…getLineCount() - 1).

    Specified by:

    getLineDescent in class Layout

  • getLineStart

    public int getLineStart(int line)

    Description copied from class: Layout
    Return the text offset of the beginning of the specified line ( 0…getLineCount()). If the specified line is equal to the line count, returns the length of the text.

    Specified by:

    getLineStart in class Layout

    public boolean getLineContainsTab(int line)

    Description copied from class: Layout
    Returns whether the specified line contains one or more characters that need to be handled specially, like tabs or emoji.
