    Default inline function in qdatetime.h

    In qt-x11-opensource-src-4.2.2/src/corelib/tools/qdatetime.h, line 40 has
    Qt Code:
    1. bool isNull() const { return jd == 0; }
    To copy to clipboard, switch view to plain text mode 
    and line 101 has
    Qt Code:
    1. inline int toJulianDay() const { return jd; }
    To copy to clipboard, switch view to plain text mode 
    As I understand it, all functions defined inside a class definition are automatically inline. Then why does line 101 have the inline keyword while line 40 does not? Is there any special meaning?

    Default Re: inline function in qdatetime.h

    my guess is that the two functions were not written by the same person or/and at the same time.
    There is no difference between the two declerations from the compilers perspective.
