In this section we describe the features of pcre2test that can be used to test these functions. - When a pattern with push modifier is successfully compiled, it is - pushed onto a stack of compiled patterns, and pcre2test expects the - next line to contain a new pattern (or command) instead of a subject - line. By contrast, the pushcopy modifier causes a copy of the compiled - pattern to be stacked, leaving the original available for immediate - matching. By using push and/or pushcopy, a number of patterns can be - compiled and retained. These modifiers are incompatible with posix, and - control modifiers that act at match time are ignored (with a message) - for the stacked patterns. The jitverify modifier applies only at com- - pile time. + Note that "serialization" in PCRE2 does not convert compiled patterns + to an abstract format like Java or .NET.
