# The RegexIterator class

## 導入

This iterator can be used to filter another iterator based on a regular expression.

## クラス概要

RegexIterator
RegexIterator extends FilterIterator {
/* 定数 */
const integer MATCH = 0 ;
const integer GET_MATCH = 1 ;
const integer ALL_MATCHES = 2 ;
const integer SPLIT = 3 ;
const integer REPLACE = 4 ;
const integer USE_KEY = 1 ;
/* メソッド */
__construct ( Iterator `$iterator` , string `$regex` [, int `$mode` [, int `$flags` [, int `$preg_flags` ]]] )
public bool accept ( void )
public int getFlags ( void )
public int getMode ( void )
public int getPregFlags ( void )
public void setFlags ( int `$flags` )
public void setMode ( int `$mode` )
public void setPregFlags ( int `$preg_flags` )
/* 継承したメソッド */
abstract bool FilterIterator::accept ( void )
FilterIterator::__construct ( Iterator `$iterator` )
mixed FilterIterator::current ( void )
Iterator FilterIterator::getInnerIterator ( void )
mixed FilterIterator::key ( void )

## 定義済み定数

## RegexIterator operation modes

`RegexIterator::ALL_MATCHES`

  Return all matches for the current entry (see preg_match_all()).

`RegexIterator::GET_MATCH`

  Return the first match for the current entry (see preg_match()).

`RegexIterator::MATCH`

  Only execute match (filter) for the current entry (see preg_match()).

`RegexIterator::REPLACE`

  Replace the current entry (see preg_replace(); Not fully implemented yet)

`RegexIterator::SPLIT`

  Returns the split values for the current entry (see preg_split()).

## RegexIterator Flags

`RegexIterator::USE_KEY`

  Special flag: Match the entry key instead of the entry value.
