## Classes

class | reflex::AbstractMatcher
| The abstract matcher base class template defines an interface for all pattern matcher engines. More...
struct | reflex::AbstractMatcher::Const
| AbstractMatcher::Const common constants. More...
struct | reflex::AbstractMatcher::Context
| Context returned by before() and after() More...
struct | reflex::AbstractMatcher::Handler
| Event handler functor base class to invoke when the buffer contents are shifted out, e.g. for logging the data searched. More...
struct | reflex::AbstractMatcher::Option
| AbstractMatcher::Options for matcher engines. More...
class | reflex::AbstractMatcher::Iterator< T >
| AbstractMatcher::Iterator class for scanning, searching, and splitting input character sequences. More...
class | reflex::AbstractMatcher::Operation
| AbstractMatcher::Operation functor to match input to a pattern, also provides a (const) AbstractMatcher::iterator to iterate over matches. More...
class | reflex::PatternMatcher< P >
| The pattern matcher class template extends abstract matcher base class. More...
class | reflex::PatternMatcher< std::string >
| A specialization of the pattern matcher class template for std::string, extends abstract matcher base class. More...

## Macros

#define | REFLEX_OVERRIDE
| Permit legacy C++ compilation of override (ignored) and C++11 override (applied). More...
#define | REFLEX_LIKELY(x) (x)
| Optimize (un)likely branches. More...
#define | REFLEX_UNLIKELY(x) (x)
#define | WITH_REALLOC 1
| This compile-time option may speed up buffer reallocation with realloc() instead of new and delete. More...
#define | WITH_FAST_GET 1
| This compile-time option speeds up matching, but slows input() somewhat. More...
#define | WITH_SPAN 1
| This compile-time option adds span(), line(), wline(), bol(), eol(). More...

## Functions

int | reflex::isword (int c)
| Check ASCII word-like character `[A-Za-z0-9_]`, permitting the character range 0..303 (0x12f) and EOF. More...
std::ostream & | operator<< (std::ostream &os, const reflex::AbstractMatcher &matcher)
| Write matched text to a stream. More...
std::istream & | operator>> (std::istream &is, reflex::AbstractMatcher &matcher)
| Read stream and store all content in the matcher's buffer. More...
