| 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 | ||

| 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. | |

| 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. | |
