Member Enumeration Documentation

enum de::zib::gndms::common::model::common::AccessMask::AccessFlags

AccessFlags is an enumeration for the different access types.

Its value can be chosen by bit flags. In detail an int value will be interpreted as follows:

 If we have an int x = x1 x2 x3 in binary representation with x element of [0;7]
 then if set to 1 the meaning of the flags are
        x3 = Executable
        x2 = Writable
        x1 = Readable
 

Enumerator:

READABLE	Read access.
WRITABLE	Write access.
EXECUTABLE	Execution access.
READWRITE	Read and write access.
READEXECUT	Read and execution access.
WRITEEXEC	write and execution access.
ALL	Unrestricted access.
NONE	No access.
