Interface com.oroinc.text.regex.Pattern

public interface Pattern
extends Object
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 implmentations. The documentation accompanying a specific implementation will define what other classes a Pattern can interact with.

Methods

 o getPattern
  public abstract String getPattern()
This method returns the string representation of the pattern. Its purpose is to allow a pattern to be reconstructed after compilation. In other words, when you compile a pattern, the resulting data structures bear no relation to the string defining the pattern. It is often useful to be able to access the string defining a pattern after it has been compiled.

Returns:
The original string representation of the regular expression pattern.
