| |
| procedure Exchange_Declarations (Id : Entity_Id); |
| -- Exchange private and full declaration on entry/exit from a package |
| -- declaration or body. The semantic links of the respective nodes |
| -- are preserved in the exchange. |

| procedure Install_Visible_Declarations (P : Entity_Id); |
| procedure Install_Private_Declarations (P : Entity_Id); |
| |
| -- On entrance to a package body, make declarations in package spec |
| -- immediately visible. |
| |
| -- When compiling the body of a package, both routines are called in |
| -- succession. When compiling the body of a child package, the call |
| -- to Install_Private_Declaration is immediate for private children, |
| -- but is deffered until the compilation of the private part of the |
| -- child for public child packages. |
| |
| procedure Install_Package_Entity (Id : Entity_Id); |
| -- Basic procedure for the previous two. Places one entity on its |
| -- visibility chain, and recurses on the visible part if the entity |
| -- is an inner package. |
| |
| function Unit_Requires_Body (P : Entity_Id) return Boolean; |
| -- Check if a unit requires a body. A specification requires a body |
| -- if it contains declarations that require completion in a body. |
| |
| procedure May_Need_Implicit_Body (E : Entity_Id); |
| -- If a package declaration contains tasks and does not require a |
| -- body, create an implicit body at the end of the current declarative |
| -- part to activate those tasks. |
| |
| function Is_Fully_Visible (Type_Id : Entity_Id) return Boolean; |
| -- Indicates whether the Full Declaration of a private type is visible. |
| |
| procedure New_Private_Type (N : Node_Id; Id : Entity_Id; Def : Node_Id); |
| -- Common processing for private type declarations and for formal |
| -- private type declarations. For private types, N and Def are the type |
| -- declaration node; for formal private types, Def is the formal type |
| -- definition. |
| |
| procedure Uninstall_Declarations (P : Entity_Id); |
| -- At the end of a package declaration or body, declarations in the |
| -- visible part are no longer immediately visible, and declarations in |
| -- the private part are not visible at all. For inner packages, place |
| -- visible entities at the end of their homonym chains. For compilation |
| -- units, make all entities invisible. In both cases, exchange private |
| -- and visible declarations to restore order of elaboration. |
