@THausherr , I found one case for COSParser.findString when this method
returns wrong result. Maybe it is impossible because of string pattern in my
test cant happen in real pdf. What can you say?
static class SRC{
int []arr = new int[30];
int position;
SRC(String body){
for (int i = 0; i < body.length(); ++i)
arr[i] = body.charAt(i);
}
int read(){
return arr.length > position ? arr[position++] : -1;
}
long getPosition(){
return position;
}
}
private static long findString(char[] string, SRC source)
{
long position = -1L;
int stringLength = string.length;
int counter = 0;
int readChar = source.read();
while (readChar != -1)
{
if (readChar == string[counter])
{
if (counter == 0)
{
position = source.getPosition() - 1;
}
counter++;
if (counter == stringLength)
{
return position;
}
}
else if (counter > 0)
{
counter = 0;
position = -1L;
continue;
}
readChar = source.read();
}
return position;
}
public static void main(String[]args) {
System.out.println(findString("aaaaaba".toCharArray(), new
SRC("aaaaaaaba")));
System.out.println("aaaaaaaba".contains("aaaaaba"));
}
