* Converts a Java string into a UTF-8 encoded, null-terminated C string, storing the result into a memory segment.
String s1 = String.valueOf("123”);
String s2 = new String(new char[]{0, 0, 0});
seg1 = session.allocateUtf8String(s1);
seg2 = session.allocateUtf8String(s2);
seg1.byteSize() == seg2.byteSize() == 4
From C point of view seg2 == “\0\0\0\0” isn’t C string it’s a string literal.A null-terminated byte string - is a sequence of zero or more characters followed by a byte with value zero
Also, potentially, it is place to get loss of data integrity
String s1 = new String(new char[]{'a', 'b', 0, 'd'});
segment = session.allocateUtf8String(s1);
String s2 = segment.getUtf8String(0);
s1 != s2
String s1 = String.valueOf("123”);
String s2 = new String(new char[]{0, 0, 0});
seg1 = session.allocateUtf8String(s1);
seg2 = session.allocateUtf8String(s2);
