Info

OTT Utility Reference MAPFUNC Parameter For C++ only. This parameter specifies the name of the function to be used to register the mappings generated by the OTT utility. This parameter is optional for the generation of C++. If this parameter is omitted, then the name of the function to register the mappings is derived from the filename specified in the MAPFILE parameter. This parameter may be specified either on the command line or in the INTYPE file. MAPFUNC=functionname OUTTYPE Parameter This parameter specifies the name of the file into which the OTT utility writes type information for all the object datatypes it processes. This file includes all types explicitly named in the INTYPE file, and may include additional types that are translated because they are used in the declarations of other types that need to be translated. This file may be used as an INTYPE file in a future invocation of the OTT utility. OUTTYPE=filename If the INTYPE and OUTTYPE parameters refer to the same file, then the new INTYPE information replaces the old information in the INTYPE file. This provides a convenient way for the same INTYPE file to be used repeatedly in the cycle of altering types, generating type declarations, editing source code, precompiling, compiling, and debugging. This parameter is required. If the filename specified for the OUTTYPE parameter on the command line or in the INTYPE file does not include an extension, a platform-specific extension such as TYP or .typ is automatically added. SCHEMA_NAMES Parameter This parameter offers control in qualifying the database name of a type from the default schema with a schema name in the OUTTYPE file. The OUTTYPE file generated by the OTT utility contains information about the types processed by the OTT utility, including the type names. SCHEMA_NAMES=ALWAYS|IF_NEEDED|FROM_INTYPE The default value is ALWAYS. 7-124 Oracle C++ Call Interface Programmer’s Guide
See Also: "SCHEMA_NAMES Usage" on page 7-131 for further information OTT Utility Reference TRANSITIVE Parameter This parameter indicates whether type dependencies not explicitly listed in the INTYPE file are to be translated. Valid values are TRUE and FALSE. TRANSITIVE=TRUE|FALSE The default value is TRUE. If TRANSITIVE=TRUE is specified, then types needed by other types and not mentioned in the INTYPE file are generated. If TRANSITIVE=FALSE is specified, then types not mentioned in the INTYPE file are not generated, even if they are used as attribute types of other generated types. USE_MARKER Parameter This parameter indicates whether OTT markers should be supported, if used, by OTT to carry forward user added. Valid values are TRUE and FALSE. The default value is FALSE. USE_MARKER=TRUE|FALSE The default value is FALSE. If USE_MARKER=TRUE is specified, then the added code between the markers, OTT_ USER_CODESTART and OTT_USERCODE_END will be carried forward when the same file is generated again. If USE_MARKER=FALSE is specified, then the user added code will not be carried forward, even if the code is added between OTT_USERCODE_START and OTT_ USERCODE_END markers. USERID Parameter This parameter specifies the Oracle username, password, and optional database name (Oracle Net database specification string). If the database name is omitted, the default database is assumed. USERID=username/password[@db_name] If this is the first parameter, then USERID= may be omitted as shown: How to Use the Object Type Translator Utility 7-125
