Serializable
UncheckedRE is a subclass of RE that allows programmers an easier means
of programmatically precompiling regular expressions. It is constructed
and used in exactly the same manner as an instance of the RE class; the
only difference is that its constructors do not throw REException.
Instead, if a syntax error is encountered during construction, a
RuntimeException will be thrown.
Note that this makes UncheckedRE dangerous if constructed with dynamic data. Do not use UncheckedRE unless you are completely sure that all input being passed to it contains valid, well-formed regular expressions for the syntax specified.

UncheckedRE
Constructs a regular expression pattern buffer without any compilation flags set, and using the default syntax (RESyntax.RE_SYNTAX_PERL5).- Parameters:
pattern
- A regular expression pattern, in the form of a String, StringBuffer or char[]. Other input types will be converted to strings using the toString() method.- Throws:
RuntimeException
- The input pattern could not be parsed.NullPointerException
- The pattern was null.
