| 释义 | Examples of pointerThese examples are from corpora and from sources on the web. Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors. Garbage collectors like to move an object from one place to another; but then they need to update all the pointers to the object. The ptr nonterminal generates pointers, which are used indicies into the store and are compared for equality. A substitution in this case is represented by the global state of the pointers. What is more, corporately held property seems to have remained important as pointers in the terrain, demarcating kinship clusters of a common agnatic ascent order. Before going into these details, we note that this formalization of model-checking is specific to "first-order" uses of code pointers. The compiler therefore builds the necessary subparts first, and pushes pointers to them on the stack, before the final expression is built. Because code regions and instance pointers are second-class constructs, we always know which code region an instruction affects. The article concludes by discussing some pointers raised by the exchange for furthering the agent-structure debate. Our syntax admits stores and configurations that include dangling pointers and unbound variables. An efficient implementation of unification relies on representing variables as pointers to terms. They treat a programming language with multiple assignment, (recursive) first-order procedures and pointers. The remainder of the object is called the payload, and may consist of a mixture of pointers and non-pointers. Starting with cell 1, a sequence of cells appears by following the pointers. We want to define an abstract notion of tree with pointers, described as a set of branches, or positions. We then consider issues related to reconfiguration features in real systems and give some pointers to how one might proceed in this direction. Indeed, objects are typically structures that receive multiple pointers. The arcs interconnect the concepts and represent lexical-semantic relations ; they are implemented by means of frame slots containing pointers to other concepts. We also provide pointers to techniques in the literature that are appropriate for more complicated scenarios. An output string is either a character, or a substitute for a dictionary entry, or a concatenation of two already defined strings represented by pointers. Finally, we conclude with discussion of our results and pointers to future work in section 6. Showing pointers of statistical interestingness reduces the glut of rules to be examined. Identifiers and pointers will be translated to the database keys. By traversing the binding chain defined by the binding pointers, it can find the value of any identifier in scope at the initially given event. The global list itself contains pointers to cells of different types. A concurrent garbage collector might have trouble finding all these pointers quickly. The update routine must then be careful to save any pointers being returned in registers into a place where the garbage collector will find them. When an update frame is removed, the stack-base pointers for the next update frame above it need to be adjusted. One possibility is to distinguish pointers from non-pointers with a tag bit (usually the least-significant bit). Firstly, the arguments may be a mixture of pointers and non-pointers so each must be pushed on the appropriate stack. The introduction of pointers into the stack raises a delicate issue for the type system. The proof is complex and surprisingly subtle, in part because active regions may contain dangling pointers that refer to de-allocated regions. With graph reduction pointers to sub-expressions are copied rather than the full text. A directory is a webpage consisting of a collection of links (or pointers) to other webpages with, it is hoped, the desired content. During this pass, the choice point links are restored again, the trail is compacted and the trail pointers in the choice points adapted accordingly. Both active and idle agents will replace their choice-points with pointers to the corresponding shared frames. In our implementation, we use copies of objects rather than pointers to objects. The lead summations invariably are not conclusions or definite pointers, but rather suggestions as to where future research should go. Indexed objects serve as pointers that allow the subject to access and revisit locations in a distal environment without engaging attention. In typical implementations, the keys at each node are stored in increasing order and at each node one has m pointers to the subtrees. The associated genetic variations can serve as powerful pointers to the region of the human genome where the disease-causing problem resides. 14. Prior to steel construction, church towers and spires were the sole pointers to the sky. In the last analysis, mental images are pointers (to operations, viz., to models) that for their part can be operated on. Language features which have been studied using -like techniques include cryptography, object-oriented languages, distribution, concurrent higher-order languages, pointers, heap regions and exceptions. Arrays, pointers, strings are all discussed roughly in the same place in all three texts. Further consideration of the turbulence of the prebiotic soup (itself influenced by tidal ebb and flow) may provide new pointers to prebiotic evolution. In the generic case, these vectors will usually be implemented as a sequence of machine words, either integers or pointers to more complex values. In an imperative setting, this would be done by reversing pointers. The editors also maintain a website containing a list of online conference material and pointers to commercial products. However, one can trace the intermediate molecules, as well as the assembly process, just by tracing the sequence of pointers in the molecule. There are some helpful pointers to how these issues could be dealt with in some existing work. Ørbaeligk (1995) introduced the concept of trust analysis for a first order imperative language with pointers using abstract interpretation and constraints. What such a novice needs is an expert guide who can provide a summary of the key ideas and pointers to the most important publications. Information about focus is inferred from the dialogue history, using two pointers into its structure: global-context and local-context. We cover some of the ways these challenges have been addressed, and provide pointers for future directions in realizing the goal of practical argumentation. We use l to range over nats when they are used as pointers. The reference count holds the number of pointers pointing at that node. The previous stack pointers allow 'the stack which came before' to be identified. The first rule expresses that normal forms are pointers to either -abstractions, partial applications or constructions. I believe our exchange has succeeded in surfacing some pointers on how the agent-structure debate may move forward. Finally, the typing rule for letregion is extremely subtle because of the interplay of dangling pointers and effects. The second logic extends the first with pointers, at the level of both programmes and assertions. Firstly, a layer of indirection has been imposed, because labels are not implemented directly as code pointers. Overwriting the thunk for 1 with a black hole immediately it is entered solves this space leak, because a black hole retains no pointers. Both chapters set an overview of the area without implementation details, and provide useful pointers to the reader in the literature. In a distributed memory architecture, the addition of an extra node type to represent non-local pointers simplifies the definition of a distributed memory machine significantly. The literature offers some useful pointers in helping to articulate public health nursing roles, functions and practices in primary care. Indeed, name-testing, like testing equality between pointers in imperative languages, prevents many useful program optimisations and transformations. In automated hyperlinking, rewriting dictionaries translate natural language expressions into ontological concepts, links and pointers. Section 5 ends the discussion with some general conclusions and pointers for future research. The question is: how is the garbage collector to find all such pointers? On the positive side, these perceived problems provide pointers for progress towards appropriate environmental guidelines. The book also contains a substantial list of references (some 24 pages) that provides pointers to more in-depth literature. Each binding stores two pointers: one to be followed if the argument matches the binding, the other to be followed otherwise. Namely, viewing locations as pointers, an environment can be intuitively seen as a tree of frames. Moreover, both solutions continue to make use of (top-level) function pointers. Then an 'equality interpreter' can recursively traverse data structures to test bitwise equality on non-pointers, and structural equality on pointers. Consider first the length of the pointers to stems. Finally, we would like to express appreciation for the useful comments and pointers provided by anonymous reviewers. Text-nodes do not have any internal structuring of their own, but rather are defined through pointers to elements at other linguistic levels. In its macronuclear form, a gene no longer has pointers. Answers allow us to encode the continuations of the computations using pointers: they are bound, just as variables are. There are many ' summary ' sections in the text and pointers to ' further reading ' clearly aimed at beginners. We will also give pointers to emerging technologies for supporting the organisation and deployment of meta-knowledge. Any logic programming system is likely to implement sharing of terms obtained by copying multiple pointers to the same subterm. One possibility is that the subject need only retain, in short-term memory, pointers to the dimensions while accessing category divisions one dimension at a time. There is scope for more work on this, but already there are tentative pointers to the picture being similar. The penalty paid for this is increased complexity when setting up the pointers and accessing and updating the database. Along with these are associated pointers containing the addresses of the record(s) with those corresponding field values. Stimulus-driven indexing creates pointers that support fast and frugal cognition. They constitute no more than pointers towards an agenda for more detailed, empirical research. What are the practical implications of following these pointers? He concludes, however, by giving a few pointers towards possible future developments which should encourage progress. We conclude by discussing theoretical underpinnings and by providing some pointers to current directions. Numerous examples of hybrid systems, with pointers to significant references, are provided. Such a queue can be easily implemented as a circular array of task pointers. At garbage collection, only the live pointers in the environment are followed in the copy- or mark-phase. The architecture we will describe cannot be used in the verification of programs with first-class code pointers, to name just one major weakness. Since field references inside a thunk remain as pointers, they could easily be rebound with only modest changes to the runtime. These examples are from corpora and from sources on the web.
