CachingIterator クラス

(PHP 5, PHP 7)

はじめに

このオブジェクトは、別のイテレータからキャッシュされた反復処理をサポートします。

CachingIterator extends IteratorIterator implements OuterIterator , ArrayAccess , Countable {

/* 定数 */

const integer CALL_TOSTRING = 1 ;

const integer CATCH_GET_CHILD = 16 ;

const integer TOSTRING_USE_KEY = 2 ;

const integer TOSTRING_USE_CURRENT = 4 ;

const integer TOSTRING_USE_INNER = 8 ;

const integer FULL_CACHE = 256 ;

/* メソッド */

public current ( void ) : void

public getCache ( void ) : array

public getFlags ( void ) : int

public getInnerIterator ( void ) : Iterator

public hasNext ( void ) : void

public key ( void ) : scalar

public next ( void ) : void

public offsetExists ( string $index ) : void

}

CachingIterator::CALL_TOSTRING: Convert every element to string.
CachingIterator::CATCH_GET_CHILD: Don't throw exception in accessing children.
CachingIterator::TOSTRING_USE_KEY: Use key for conversion to string.
CachingIterator::TOSTRING_USE_CURRENT: Use current for conversion to string.
CachingIterator::TOSTRING_USE_INNER: Use inner for conversion to string.
CachingIterator::FULL_CACHE: Cache all read data.
