org.apache.oro.text.regex.Pattern
The Pattern interface allows multiple representations of a regular expression to be defined. In general, different regular expression compilers will produce different types of pattern representations. Some will produce state transition tables derived from syntax trees, others will produce byte code representations of an NFA, etc. The Pattern interface does not impose any specific internal pattern representation, and consequently, Pattern implementations are not meant to be interchangeable among differing PatternCompiler and PatternMatcher implementations. The documentation accompanying a specific implementation will define what other classes a Pattern can interact with. @version @version@ @since 1.0 @see PatternCompiler @see PatternMatcher
