Class UncheckedRE

java.lang.Object
  gnu.regexp.RE
      gnu.regexp.UncheckedRE

All Implemented Interfaces:

java.io.Serializable

public final class UncheckedRE
extends RE

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.

Since:

gnu.regexp 1.1.4

UncheckedRE(java.lang.Object pattern, int cflags, RESyntax syntax)
Constructs a regular expression pattern buffer using the specified compilation flags and regular expression syntax.

Constructor Detail

UncheckedRE

public UncheckedRE(java.lang.Object pattern)

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:

java.lang.RuntimeException - The input pattern could not be parsed.

java.lang.NullPointerException - The pattern was null.

UncheckedRE

public UncheckedRE(java.lang.Object pattern,
                   int cflags)

Constructs a regular expression pattern buffer using the specified compilation flags and 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.

cflags - The logical OR of any combination of the compilation flags in the RE class.

Throws:

java.lang.RuntimeException - The input pattern could not be parsed.

java.lang.NullPointerException - The pattern was null.

UncheckedRE

public UncheckedRE(java.lang.Object pattern,
                   int cflags,
                   RESyntax syntax)

Constructs a regular expression pattern buffer using the specified compilation flags and regular expression syntax.

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.

cflags - The logical OR of any combination of the compilation flags in the RE class.

syntax - The type of regular expression syntax to use.

Throws:

java.lang.RuntimeException - The input pattern could not be parsed.

java.lang.NullPointerException - The pattern was null.
