J.15.15 Distribution Pragmas
This subclause defines pragmas that specify properties of units for distributed systems.
Syntax
The following pragmas are defined with the given forms:
pragma Shared_Passive[(library_unit_name)];
pragma Remote_Types[(library_unit_name)];
pragma Remote_Call_Interface[(library_unit_name)];
pragma All_Calls_Remote[(library_unit_name)];
Each of these pragmas is a library unit pragma.
Static Semantics
A categorization pragma is a pragma that specifies a corresponding categorization aspect.
The pragmas Shared_Passive, Remote_Types, and Remote_Call_Interface are categorization pragmas. In addition, the pragma Pure (see J.15.14) is considered a categorization pragma.
A pragma Shared_Passive specifies that a library unit is a shared passive library unit, namely that the Shared_Passive aspect (see E.2.1) of the library unit is True.
A pragma Remote_Types specifies that a library unit is a remote types library unit, namely that the Remote_Types aspect (see E.2.2) of the library unit is True.
A pragma Remote_Call_Interface specifies that a library unit is a remote call interface, namely that the Remote_Call_Interface aspect (see E.2.3) of the library unit is True.
A pragma All_Calls_Remote specifies that the All_Calls_Remote aspect (see E.2.3) of the library unit is True.
