| 32 -- This package provides an alternate way of populating the internal tables | |
| 33 -- of Repinfo from a JSON input rather than the binary blob of the tree file. | |
| 34 -- Note that this is an additive mechanism, i.e. nothing is destroyed in the | |
| 35 -- internal state of the unit when it is used. | |
| 36 | |
| 37 -- The first step is to feed the unit with a JSON stream of a specified format | |
| 38 -- (see the spec of Repinfo for its description) by means of Read_JSON_Stream. | |
| 39 -- Then, for each entity whose representation information is present in the | |
| 40 -- JSON stream, the appropriate Get_JSON_* routines can be invoked to override | |
| 41 -- the eponymous fields of the entity in the tree. | |
| 42 | |

| 44 | |
| 45 function Get_JSON_Esize (Name : String) return Node_Ref_Or_Val; | |
| 46 -- Returns the Esize value of the entity specified by Name, which is not | |
| 47 -- the component of a record type, or else No_Uint if no representation | |
| 48 -- information was supplied for the entity. Name is the full qualified name | |
| 49 -- of the entity in lower case letters. | |
| 50 | |
| 51 function Get_JSON_RM_Size (Name : String) return Node_Ref_Or_Val; | |

| 57 function Get_JSON_Component_Bit_Offset | |
| 58 (Name : String; | |
| 59 Record_Name : String) return Node_Ref_Or_Val; | |
| 60 -- Returns the Component_Bit_Offset of the component specified by Name, | |
| 61 -- which is declared in the record type specified by Record_Name, or else | |
| 62 -- No_Uint if no representation information was supplied for the component. | |
| 63 -- Name is the unqualified name of the component whereas Record_Name is the | |
| 64 -- full qualified name of the record type, both in lower case letters. | |
