DESCRIPTION

This abstract class provides methods for the PPIx::Regexp support classes.

METHODS

This class provides the following public methods. Methods not documented here are private, and unsupported in the sense that the author reserves the right to change or remove them without notice.

close_bracket

This method takes as its argument a character. If this character is an open bracket the corresponding close bracket is returned. Otherwise undef is returned. Only the ASCII bracket characters are considered brackets: (), {}, [], and <>.

decode

This method wraps the Encode::decode subroutine. If the object specifies no encoding or encode_available() returns false, this method simply returns its input string.

encode

This method wraps the Encode::encode subroutine. If the object specifies no encoding or encode_available() returns false, this method simply returns its input string.

encode_available

This method returns true if the Encode module is available, and false otherwise. If it returns true, the Encode module has actually been loaded.
