Description copied from interface: SplitCharacter

Returns true if the character can split a line. The splitting implementation is free to look ahead or look behind characters to make a decision.

The default implementation is:

 public boolean isSplitCharacter(int start, int current, int end, char[] cc, PdfChunk[] ck) {
    char c;
    if (ck == null)
        c = cc[current];
    else
        c = (char) ck[Math.min(current, ck.length - 1)].getUnicodeEquivalent(cc[current]);
    if (c <= ' ' || c == '-') {
        return true;
    }
    if (c < 0x2e80)
        return false;
    return ((c >= 0x2e80 && c < 0xd7a0)
    || (c >= 0xf900 && c < 0xfb00)
    || (c >= 0xfe30 && c < 0xfe50)
    || (c >= 0xff61 && c < 0xffa0));
 }
 

Specified by:

isSplitCharacter in interface SplitCharacter

Parameters:

start - the lower limit of cc inclusive

current - the pointer to the character in cc

end - the upper limit of cc exclusive

cc - an array of characters at least end sized

ck - an array of PdfChunk. The main use is to be able to call PdfChunk.getUnicodeEquivalent(int). It may be null or shorter than end. If null no conversion takes place. If shorter than end the last element is used

Returns:

true if the character(s) can split a line
