单词 nesting
释义
nesting
Computer

  • A feature of language design in which constructs can be embedded within instances of themselves, e.g. nested loops:

    • while b1 do
    • begin
    • while b2 do
    • begin
    • …
    • end;
    • end;

    Nesting of blocks in block-structured languages provides an elegant, though not entirely practicable, control over the scope of identifiers, since identifiers are local to the innermost level of nesting at which they are declared.

Electronics and Electrical Engineering

  • The process in which something is contained or embedded within something else of the same type. Nesting is quite common in programming; examples include ‘loops’ and ‘if’ statements.

Geography

  • The way in which one network fits into a larger one. For example, Inkpen et al. (2007) Area 39, 4, see scale as a nested hierarchy. Species communities often exhibit nested assemblages, the species found in species-poor sites representing subsets of richer ones (Schouten et al. (2007) J. Biogeog. 34, 11).
