predictive parsing造句

Predictive parsing is possible only for the class of LL ( " k " ) grammars, which are the context-free grammars for which there exists some positive integer " k " that allows a recursive descent parser to decide which production to use by examining only the next " k " tokens of input.
Although predictive parsers are widely used, and are frequently chosen if writing a parser by hand, programmers often prefer to use a table-based parser produced by a parser generator, either for an LL ( " k " ) language or using an alternative parser, such as LL ( " k " ) form, as transforming the grammar to LL to make it suitable for predictive parsing is involved.
