Thus it is 00030 itself unallocated so that no storage is allocated or de-allocated 00031 during it's use. To achieve this behaviour, SubList is derived from 00032 UList rather than List. 00033 00034 SourceFiles 00035 SubListI.H 00036 00037 \*---------------------------------------------------------------------------*/ 00038 00039 #ifndef SubList_H 00040 #define SubList_H 00041 00042 #include "List.H" 00043 00044 // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // 00045 00046 namespace Foam 00047 { 00048 00049 /*---------------------------------------------------------------------------*\ 00050 Class SubList Declaration 00051 \*---------------------------------------------------------------------------*/ 00052 00053 template<class T> 00054 class SubList 00055 : 00056 public UList<T> 00057 { 00058 // Private member functions 00059 00060 //- Dissalow non-const return subscript-checked element of SubList. 00061 T& operator[](const label); 00062 00063 00064 public: 00065 00066 // Constructors 00067 00068 //- Construct from UList and SubList size 00069 inline SubList 00070 ( 00071 const UList<T>& list, 00072 const label subSize 00073 ); 00074 00075 //- Construct from UList, start and end indices 00076 inline SubList 00077 ( 00078 const UList<T>& list, 00079 const label subSize, 00080 const label startIndex 00081 ); 00082 00083 00084 // Member functions 00085 00086 //- Return a null SubList 00087 static inline SubList<T>& null(); 00088 00089 00090 // Member operators 00091 00092 //- Return const subscript-checked element of SubList. 00093 const T& operator[](const label l) const 00094 { 00095 return UList<T>::operator[](l); 00096 } 00097 00098 //- Allow cast to a const List<T>& 00099 inline operator const List<T>&() const; 00100 }; 00101 00102 00103 // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // 00104 00105 } // End namespace Foam 00106 00107 // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // 00108 00109 #include "SubListI.H" 00110 00111 // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // 00112 00113 #endif 00114 00115 // ************************************************************************* //
