2 mapped variable An original variable in a data environment with a corresponding variable in a device data environment. 34 COMMENT:The original and corresponding variables may share storage. 567 mappable type Atype that is valid.Ifa type is from other types not mappable 89 COMMENT:Pointer types are mappable but the memory block to which the pointer refers is not mapped. For C: 11 The type must be a complete type For C++ The type must be a complete type 14 In addition,for class types: All member functions accessed in any target region must appear in a declare target directive. 17 All data members must be non-static 8 A mappable type cannot contain virtual members 20 For Fortran The type must be definable 名 defined For variables,the property of having a valid value. 2324 For the contents of variables,the property of having a valid value 25 For C++ 2 For the contents of variables of POD (plain old data)type,the property of having a valid value 2 For variables of non-POD class type,the property of having been constructed but not subsequently destructed. 303 For Fortran For the contents of variables,the property of having a valid value.For the 32 allocation or association status of variables,the property of having a valid status. COMMENT:Programs that rely upon variables that are not defined are 34 non-conforming program 35 class type For C++:Variables declared with one of the class,struct,or union keywords. Chapter 1 Introduction 11Chapter 1 Introduction 11 mapped variable An original variable in a data environment with a corresponding variable in a device data environment. COMMENT: The original and corresponding variables may share storage. mappable type A type that is valid for a mapped variable. If a type is composed from other types (such as the type of an array or structure element) and any of the other types are not mappable then the type is not mappable. COMMENT: Pointer types are mappable but the memory block to which the pointer refers is not mapped. For C: The type must be a complete type. For C++: The type must be a complete type. In addition, for class types: • All member functions accessed in any target region must appear in a declare target directive. • All data members must be non-static. • A mappable type cannot contain virtual members. For Fortran: The type must be definable. defined For variables, the property of having a valid value. For C: For the contents of variables, the property of having a valid value. For C++: For the contents of variables of POD (plain old data) type, the property of having a valid value. For variables of non-POD class type, the property of having been constructed but not subsequently destructed. For Fortran: For the contents of variables, the property of having a valid value. For the allocation or association status of variables, the property of having a valid status. COMMENT: Programs that rely upon variables that are not defined are non-conforming programs. class type For C++: Variables declared with one of the class, struct, or union keywords. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35
