In computing, a pointer or mouse pointer (as part of a personal computer WIMP style of interaction) [10] [11] [12] is a symbol or graphical image on the computer monitor or other display device that echoes movements of the pointing device, commonly a mouse, touchpad, or stylus pen. It signals the point where actions of the user take place.
At runtime, this program creates three separate heap allocations. A flow-insensitive pointer analysis would treat these as a single abstract memory location, leading to a loss of precision. Many flow-insensitive algorithms are specified in Datalog, including those in the Soot analysis framework for Java. [7]
Cursor (databases), a control structure that enables traversal over the records in a database; Cursor, a value that is the position of an object in some known data structure, a predecessor of pointers; Cursor (slide rule), indicates corresponding points on scales that are not adjacent to each other
position control vs. rate control; A position-control input device (e.g., mouse, finger on touch screen) directly changes the absolute or relative position of the on-screen pointer. A rate-control input device (e.g., trackpoint, joystick) changes the speed and direction of the movement of the on-screen pointer. translation vs. rotation
A pointer a pointing to the memory address associated with a variable b, i.e., a contains the memory address 1008 of the variable b.In this diagram, the computing architecture uses the same address space and data primitive for both pointers and non-pointers; this need should not be the case.
Iterators generalize pointers to elements of an array (which indeed can be used as iterators), and their syntax is designed to resemble that of C pointer arithmetic, where the * and -> operators are used to reference the element to which the iterator points and pointer arithmetic operators like ++ are used to modify iterators in the traversal ...
The subtraction linked list is also special in that the entire list can be relocated in memory without needing any patching of pointer values, since adding a constant offset to each address in the list will not require any changes to the values stored in the link fields. (See also serialization.) This is an advantage over both XOR linked lists ...
This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language.
