Analyzes characters for a specific character set.
Public Methods
Method | Description | Defined By |
---|---|---|
getCharPositions() | Returns the complete character map. | Swift_CharacterReader |
getInitialByteSize() | Returns the number of bytes which should be read to start each character. | Swift_CharacterReader |
getMapType() | Returns the mapType, see constants. | Swift_CharacterReader |
validateByteSequence() | Returns an integer which specifies how many more bytes to read. | Swift_CharacterReader |
Method Details
Returns the complete character map.
public abstract int getCharPositions ( $string, $startOffset, <b>&</b>$currentMap, <b>&</b>$ignoredChars ) | ||
$string | string | |
$startOffset | int | |
$currentMap | array | |
$ignoredChars | mixed |
Returns the number of bytes which should be read to start each character.
For fixed width character sets this should be the number of octets-per-character. For multibyte character sets this will probably be 1.
public abstract int getInitialByteSize ( ) |
Returns the mapType, see constants.
public abstract int getMapType ( ) |
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.
public abstract int validateByteSequence ( $bytes, $size ) | ||
$bytes | integer[] | |
$size | int |
