Constructor & Destructor Documentation

VCF::Regex::Ascii::Ascii (  const String &  expression,
const unsigned char *const   first,
const unsigned char *const   last,
const RegExKit::Syntax &  syntax = RegExKit::sDefault
) 
 

Standard constructor.

It is the user's responsibility to ensure that the data in the search range remains valid for the lifetime of the Ascii object.

Parameters:
String Regular expression.
unsigned char* Beginning of search range.
unsigned char* End of search range.
OnigSyntaxType The regex syntax used to interpret the expression.

VCF::Regex::Ascii::Ascii (  const String &  expression,

It is the user's responsibility to ensure that the String object remains valid for the lifetime of the Ascii object.

Parameters:
String Regular expression.

Implements VCF::Regex::Host.

void VCF::Regex::Ascii::setRangeAsString (  const String &  newExpression  )  [virtual]
 

Sets the search range pointers to the beginning and end of a VCF::String object.

This is implemented by classes derived from Host as the result depends on the character width and representation.

Parameters:
String Data to be searched

Implements VCF::Regex::Host.
