[Doxygen-users] Meaning of function label "read"

[Barnes, P. D. <bar...@ll...>]

Hello Folks,

The generated html labels functions by access specifier, as in:

static struct Resolution* ns3::Time::PeekResolution (void) inline static read private

(C++ example taken from ns-3:
https://www.nsnam.org/docs/doxygen/classns3_1_1_time.html#a0b023c55c20582aa7c1781aacf128034 
)

"inline", "static" and "private" are obvious.

What does "read" mean?

Thanks,
Peter
