Continuation - Wikipedia
网页In computer science, a continuation is an abstract representation of the control state of a computer program. A continuation implements (reifies) the program control state, i.e. the continuation is a data structure that represents the computational process at a given point in the process's execution; the created data structure can be accessed ...
CSE341 Lecture Notes 15: Scheme: Continuations and exceptions
网页Continuations. An expression's continuation is "the computation that will receive the result of that expression". For example, in the expression. (+ 4 (+ 1 2)) the result of (+ 1 2) will be added to 4. The addition to 4 is that expression's continuation. If we wanted to represent the continuation of (+ 1 2), we might write:
Lecture 22: Continuations - Department of Computer Science
网页Continuations are a way of thinking about program control flow in terms of explicitly passing around objects that represent computation to be done. Unlike function objects, which also represent computation to be done, continuations represent dynamic or …
网页With continuations, we can pass in a continuation which is the destination for the result of the conjunction. This allows us to escape the local context and avoid evaluating the second boolean argument to conjoin.
2.9. Continuations and Continuation Passing - Virginia Tech
网页2024年7月17日 · Continuations allow us to make the control flow and execution state of our programs explicit and thus solve this problem. A continuation is a callback function k k that represents the current state of the program’s execution.
网页we extracted the continuation of the subexpression in to a function.The nice thing about continuations is that it makes the control explicit, and this is especially useful in t. e case of functional programs, where control is not explicit otherwise.
Continuation Definition & Meaning - Merriam-Webster
网页1. : the act or fact of continuing in or the prolongation of a state or activity. 2. : resumption after an interruption. 3. : something that continues, increases, or adds. Synonyms. …
c - How to implement continuations? - Stack Overflow
网页Continuations basically consist of the saved state of the stack and CPU registers at the point of context switches. At the very least you don't have to copy the entire stack to the heap when switching, you could only redirect the stack pointer.
What's the difference between a continuation and a callback?
网页2012年12月24日 · I can see how they are easily grouped together, but continuations didn't arise from the need to distinguish from a callback. A continuation actually represents the instructions remaining to complete a computation, or the remainder of the computation from this point in time.
网页Continuations have been described as the goto of functional languages, since they allow non-local transfer of control. While they are powerful, programs that exploit continuations can difficult to reason about and their gratuitous use should therefore be avoided.
