Subclasses of GlobalFlag (that are defined in libraries) are "global" in the sense that they are accessible by any application that depends on that library. Regardless of where in a library a GlobalFlag is defined, a value for it can be passed as a command-line flag by any binary that includes the library. The set of defined GlobalFlags can be enumerated (via
GlobalFlag.getAll)
by the application.All such global flag declarations in a given classpath are visible to and used by com.twitter.app.App.
A flag's name (as set on the command line) is its fully-qualified classname. For example, the flag
is settable by the command-line flag
-com.twitter.server.port
.Global flags may also be set by Java system properties with keys named in the same way. However, values supplied by flags override those supplied by system properties.
