-package Exp_Strm is
-
- function Build_Elementary_Input_Call (N : Node_Id) return Node_Id;
- -- Build call to Read attribute function for elementary type. Also used
- -- for Input attributes for elementary types with an appropriate extra
- -- assignment statement. N is the attribute reference node.
-
- function Build_Elementary_Write_Call (N : Node_Id) return Node_Id;
- -- Build call to Write attribute function for elementary type. Also used
- -- for Output attributes for elementary types (since the effect of the
- -- two attributes is identical for elementary types). N is the attribute
- -- reference node.
-
- function Build_Stream_Attr_Profile
- (Loc : Source_Ptr;
- Typ : Entity_Id;
- Nam : Name_Id)
- return List_Id;
- -- Builds the parameter profile for the stream attribute identified by
- -- the given name (which is the underscore version, e.g. Name_uWrite to
- -- identify the Write attribute). This is used for the tagged case to
- -- build the spec for the primitive operation.
-
- -- The following routines build procedures and functions for stream
- -- attributes applied to composite types. For each of these routines,
- -- Loc is used to provide the location for the constructed subprogram
- -- declaration. Typ is the base type to which the subprogram applies
- -- (i.e. the base type of the stream attribute prefix). The returned
- -- results are the declaration and name (entity) of the subprogram.
