    • An apparatus for processing a sequence of tokens to detect predetermined data, wherein each said token has a token type, and the predetermined data has a structure that comprises a predetermined sequence of token types, including at least one optional token type. The apparatus comprises a processor arranged to: provide a tree for detecting the predetermined data, the tree comprising a plurality of states, each said state being linked with at least one other state by a respective condition, the arrangement of linked states forming a plurality of paths; and compare the token types of the sequence of tokens to respective conditions in the tree to match the sequence of tokens to one or more paths in the tree, wherein the predetermined data can be detected without using an epsilon reduction to take account of said at least one optional token type.
    • 一种用于处理令牌序列以检测预定数据的装置,其中每个所述令牌具有令牌类型,并且所述预定数据具有包括至少一个可选令牌类型的令牌类型的预定序列的结构。 该装置包括:处理器,被配置为:提供用于检测预定数据的树,该树包括多个状态,每个所述状态通过相应条件与至少一个其他状态链接,形成多个状态的链接状态的布置 路径 并将所述令牌序列的令牌类型与所述树中的相应条件进行比较,以将所述令牌序列与所述树中的一个或多个路径匹配,其中,可以在不使用ε减少的情况下检测所述预定数据以考虑所述至少 一种可选的令牌类型。
