Existing Eiffel software uses the string classes (such as STRING_8) from the Eiffel libraries, but Eiffel software written for .NET must use the .NET string class (System.String) in many cases, for example when calling .NET methods which expect items of the .NET type to be passed as arguments. So, the conversion of these types back and forth ...
The object need to handle synchronization to prevent simultaneous access from multiple threads from problems. Calls to an MTA object from a thread in an STA are also marshalled. Dynamically determined apartment Both The server auto-selects STA or MTA at object creation to match the apartment type of the calling thread. [24]
The gSOAP tools convert C/C++ data types to/from XML schema data types. Since C does not support namespaces and struct/class member names cannot be namespace-qualified in C++, the use of identifier naming conventions in gSOAP allow for binding this structure and its members to an XML schema complexType that is auto-generated as follows:
32-bit compilers emit, respectively: _f _g@4 @h@4 In the stdcall and fastcall mangling schemes, the function is encoded as _name@X and @name@X respectively, where X is the number of bytes, in decimal, of the argument(s) in the parameter list (including those passed in registers, for fastcall).
In Object Pascal, RTTI can be used to perform safe type casts with the as operator, test the class to which an object belongs with the is operator, and manipulate type information at run time with classes contained in the RTTI unit [5] (i.e. classes: TRttiContext, TRttiInstanceType, etc.). In Ada, objects of tagged types also store a type tag ...
Auto-linking is a mechanism for automatically determining which libraries to link to while building a C, C++ or Obj-C program. It is activated by means of #pragma comment(lib, <name>) statements in the header files of the library, or @import <name> , depending on the compiler.
Many languages have explicit pointers or references. Reference types differ from these in that the entities they refer to are always accessed via references; for example, whereas in C++ it's possible to have either a std:: string and a std:: string *, where the former is a mutable string and the latter is an explicit pointer to a mutable string (unless it's a null pointer), in Java it is only ...
HipHop for PHP (HPHPc) is a discontinued PHP transpiler created by Facebook. By using HPHPc as a source-to-source compiler , PHP code is translated into C++ , compiled into a binary and run as an executable , as opposed to the PHP's usual execution path of PHP code being transformed into opcodes and interpreted .
