| -- This package provides an alternate way of populating the internal tables |
| -- of Repinfo from a JSON input rather than the binary blob of the tree file. |
| -- Note that this is an additive mechanism, i.e. nothing is destroyed in the |
| -- internal state of the unit when it is used. |
| |
| -- The first step is to feed the unit with a JSON stream of a specified format |
| -- (see the spec of Repinfo for its description) by means of Read_JSON_Stream. |
| -- Then, for each entity whose representation information is present in the |
| -- JSON stream, the appropriate Get_JSON_* routines can be invoked to override |
| -- the eponymous fields of the entity in the tree. |
| |
| package Repinfo.Input is |
| |
| function Get_JSON_Esize (Name : String) return Node_Ref_Or_Val; |
| -- Returns the Esize value of the entity specified by Name, which is not |
| -- the component of a record type, or else No_Uint if no representation |
| -- information was supplied for the entity. Name is the full qualified name |
| -- of the entity in lower case letters. |
| |
| function Get_JSON_RM_Size (Name : String) return Node_Ref_Or_Val; |
| -- Likewise for the RM_Size |
| |
| function Get_JSON_Component_Size (Name : String) return Node_Ref_Or_Val; |
| -- Likewise for the Component_Size of an array type |
| |
| function Get_JSON_Component_Bit_Offset |
| (Name : String; |
| Record_Name : String) return Node_Ref_Or_Val; |
| -- Returns the Component_Bit_Offset of the component specified by Name, |
| -- which is declared in the record type specified by Record_Name, or else |
| -- No_Uint if no representation information was supplied for the component. |
| -- Name is the unqualified name of the component whereas Record_Name is the |
| -- full qualified name of the record type, both in lower case letters. |
| |
| function Get_JSON_Esize |
| (Name : String; |
| Record_Name : String) return Node_Ref_Or_Val; |
| -- Likewise for the Esize |
| |
| Invalid_JSON_Stream : exception; |
| -- Raised if a format error is detected in the JSON stream |
| |
| procedure Read_JSON_Stream (Text : Text_Buffer; File_Name : String); |
| -- Reads a JSON stream and populates internal tables from it. File_Name is |
| -- only used in error messages issued by the JSON parser. |
