getCharPositions	(		$string,
			$startOffset,
		&	$currentMap,
		&	$ignoredChars
	)

Returns the complete character map.

Parameters

string	$string
int	$startOffset
array	$currentMap
mixed	$ignoredChars

Returns

int

Implements Swift_CharacterReader.

Definition at line 85 of file Utf8Reader.php.

getInitialByteSize

(

)

Returns the number of bytes which should be read to start each character.

Returns

int

Implements Swift_CharacterReader.

Definition at line 175 of file Utf8Reader.php.

getMapType

(

)

Returns mapType.

Returns

int mapType

Implements Swift_CharacterReader.

Definition at line 139 of file Utf8Reader.php.

validateByteSequence	(		$bytes,
			$size
	)

Returns an integer which specifies how many more bytes to read.

A positive integer indicates the number of more bytes to fetch before invoking this method again. A value of zero means this is already a valid character. A value of -1 means this cannot possibly be a valid character.

Parameters

string	$bytes
int	$size

Returns

int

Implements Swift_CharacterReader.
