Type sensitivity is a variant of object sensitivity where the allocation site of the receiver object is replaced by the class/type containing the method containing the allocation site of the receiver object. [13] This results in strictly fewer contexts than would be used in an object-sensitive analysis, which generally means better performance.
An example for this is the C++ language, in which multiple inheritance can cause pointers to base objects to have different addresses. In a tightly optimized program, the corresponding pointer to the object itself may have been overwritten in its register, so such internal pointers need to be scanned.
Since the pointer placement new functions do not allocate any storage, there is no storage to [16] be deallocated in the event of the object's constructor throwing an exception. [ 11 ] If no matching placement delete function exists, no deallocation function is called in the event of an exception being thrown by a constructor within a placement ...
Each pointer has a type it points to, but one can freely cast between pointer types (but not between a function pointer and an object pointer). A special pointer type called the “void pointer” allows pointing to any (non-function) object, but is limited by the fact that it cannot be dereferenced directly (it shall be cast).
In computer science, pointer swizzling is the conversion of references based on name or position into direct pointer references (memory addresses). It is typically performed during deserialization or loading of a relocatable object from a disk file, such as an executable file or pointer-based data structure .
In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...
The following C# fragment declares a variable-length array of integers. Before C# version 7.2, a pointer to the array is required, requiring an "unsafe" context. The "unsafe" keyword requires an assembly containing this code to be marked as unsafe.
Non-static member functions (instance methods) have an implicit parameter (the this pointer) which is the pointer to the object it is operating on, so the type of the object must be included as part of the type of the function pointer. The method is then used on an object of that class by using one of the "pointer-to-member" operators: .* or ...
