You are only looking at "current" but can also look at "current + 1" and
"current - 1" to decide what to do.

Subject: [iText-questions] Question about splitCharacter

I have implemented SplitCharacter and was hoping to have it
split after the close parenthesis ')', but not before this character,
As such I have something like:

public boolean isSplitCharacter(int start, int current, int end,
char[] cc, PdfChunk[] ck) {

char c;

if (ck == null)

c = cc[current];

else

c = ck[Math.min(current, ck.length -
1)].getUnicodeEquivalent(cc[current]);

if ((c ')') || (c==' ')) {

return true;

}

This appears to work in some situations such as the breaking of
"aaa)bbb" is correct and desired as:

aaa)

bbb

However, in the case where a closing parenthesis ends the line,
it is treating it as a "split before character". In other words, the
line:

hello (test)

is split as follows:

hello (test

)

instead of what I want which is:

hello

(test)

According to the implicit definition "treat a split character as
if it can go at the beginning or end of a line" it is working, but what
I desire is "treat this split character as if it only can go on the end
of the line".

So my questions are:

1) Is there native support for this concept of the split
character being at the start or end of a contiguous set of characters?

2) If not, can I "force" it by breaking the text into chunks
that are stuck next to each other?

3) If breaking the text into chunks does not work, is the only
real remaining course of action to insert line breaks manually?

Thanks for any ideas,
