+ * SWIG API. Portion only visible from SWIG |
+ * ----------------------------------------------------------------------------- */ |
+/* |
+ This file implements the internal macros of the 'SWIG API', which |
+ are useful to implement all the SWIG target languges. |
+ |
+ Basic preprocessor macros: |
+ -------------------------- |
+ |
+ %arg(Arg) Safe argument wrap |
+ %str(Arg) Stringtify the argument |
+ %begin_block Begin a execution block |
+ %end_block End a execution block |
+ %block(Block) Execute Block as a excecution block |
+ %define_as(Def, Val) Define 'Def' as 'Val', expanding Def and Val first |
+ %ifcplusplus(V1, V2) if C++ Mode; then V1; else V2; fi |
+ |
+ |
+ Casting Operations: |
+ ------------------- |
+ |
+ Swig provides the following casting macros, which implement the |
+ corresponding C++ casting operations: |
+ |
+ %const_cast(a, Type) const_cast<Type >(a) |
+ %static_cast(a, Type) static_cast<Type >(a) |
+ %reinterpret_cast(a, Type) reinterpret_cast<Type >(a) |
+ %numeric_cast(a, Type) static_cast<Type >(a) |
+ %as_voidptr(a) const_cast<void *>(static_cast<const void *>(a)) |
+ %as_voidptrptr(a) reinterpret_cast<void **>(a) |
+ |
+ or their C unsafe versions. In C++ we use the safe version unless |
+ SWIG_NO_CPLUSPLUS_CAST is defined (usually via the -nocppcast swig flag). |
+ |
+ |
+ Memory allocation: |
+ ------------------ |
+ |
+ These allocation/freeing macros are safe to use in C or C++ and |
+ dispatch the proper new/delete/delete[] or free/malloc calls as |
+ needed. |
+ |
+ %new_instance(Type) Allocate a new instance of given Type |
+ %new_copy(value,Type) Allocate and initialize a new instance with 'value' |
+ %new_array(size,Type) Allocate a new array with given size and Type |
+ %new_copy_array(cptr,size,Type) Allocate and initialize a new array from 'cptr' |
+ %delete(cptr) Delete an instance |
+ %delete_array(cptr) Delete an array |
+ |
+ |
+ Auxiliary loop macros: |
+ ---------------------- |
+ |
+ %formacro(Macro, Args...) or %formacro_1(Macro, Args...) |
+ for i in Args |
+ do |
+ Macro($i) |
+ done |
+ |
+ %formacro_2(Macro2, Args...) |
+ for i,j in Args |
+ do |
+ Macro2($i, $j) |
+ done |
+ |
+ |
+ Flags and conditional macros: |
+ ----------------------------- |
+ |
+ %mark_flag(flag) |
+ flag := True |
+ |
+ %evalif(flag,expr) |
+ if flag; then |
+ expr |
+ fi |
+ |
+ %evalif_2(flag1 flag2,expr) |
+ if flag1 and flag2; then |
+ expr |
+ fi |
+ |
