Use comprehensible names for instances of parameterized types
With previous commit, the following data types are generated in ProtocolIE-Field.h for S1AP's ASN.1 : ``` typedef enum ProtocolIE_Field_6564P0__value_PR { ProtocolIE_Field_6564P0__value_PR_NOTHING, /* No components present */ ProtocolIE_Field_6564P0__value_PR_E_RABToBeSetupItemBearerSUReq } ProtocolIE_Field_6564P0__value_PR; typedef struct ProtocolIE_Field_6564P0 { ProtocolIE_ID_t id; Criticality_t criticality; struct ProtocolIE_Field_6564P0__value { ProtocolIE_Field_6564P0__value_PR present; union ProtocolIE_Field_6564P0__value_u { E_RABToBeSetupItemBearerSUReq_t E_RABToBeSetupItemBearerSUReq; } choice; /* Context for parsing across buffer boundaries */ asn_struct_ctx_t _asn_ctx; } value; /* Context for parsing across buffer boundaries */ asn_struct_ctx_t _asn_ctx; } ProtocolIE_Field_6564P0_t; ``` It's difficult for developer to recognize to which ASN.1 type they are linked. They all start with 'ProtocolIE_Field_'. It will be error-prone. With this commit, more human comprehensible data types are generated : ``` typedef enum E_RABToBeSetupItemBearerSUReqIEs__value_PR { E_RABToBeSetupItemBearerSUReqIEs__value_PR_NOTHING, /* No components present */ E_RABToBeSetupItemBearerSUReqIEs__value_PR_E_RABToBeSetupItemBearerSUReq } E_RABToBeSetupItemBearerSUReqIEs__value_PR; typedef struct E_RABToBeSetupItemBearerSUReqIEs { ProtocolIE_ID_t id; Criticality_t criticality; struct E_RABToBeSetupItemBearerSUReqIEs__value { E_RABToBeSetupItemBearerSUReqIEs__value_PR present; union E_RABToBeSetupItemBearerSUReqIEs__value_u { E_RABToBeSetupItemBearerSUReq_t E_RABToBeSetupItemBearerSUReq; } choice; /* Context for parsing across buffer boundaries */ asn_struct_ctx_t _asn_ctx; } value; /* Context for parsing across buffer boundaries */ asn_struct_ctx_t _asn_ctx; } E_RABToBeSetupItemBearerSUReqIEs_t; ``` Developers can understand they are generated from : ``` E-RABToBeSetupItemBearerSUReqIEs S1AP-PROTOCOL-IES ::= { { ID id-E-RABToBeSetupItemBearerSUReq CRITICALITY reject TYPE E-RABToBeSetupItemBearerSUReq PRESENCE mandatory }, ... } ```
