eZCodeMapper::appendReplaceMapping	(	&$	block,
		$	identifier,
		$	sourceValue,
		$	sourceEndValue,
		$	destinationValues
	)		`[private]`

Appends a mapping for a range of values into a specific value

Parameters:

$block	Current block it is working on
$identifier	The current identifier it is working on
$sourceValue	The start of the original value
$sourceEndValue	The ned of the original value
$destinationValues	The value it should be mapped to

		$	identifier,
		$	sourceValue,
		$	sourceEndValue,
		$	transposeValue,
		$	addValue,
		$	moduloValue
	)		`[private]`

Appends a mapping for characters by transposing them up or down.

Parameters:

$block	Current block it is working on
$identifier	The current identifier it is working on
$sourceValue	The start of the original value
$sourceEndValue	The ned of the original value
$transposeValue	How much to transpose the values
$addValue	If `true` the $transposeValue is added to the range if not it is subtracted.

eZCodeMapper::decodeCommand	(	$	name,
		$	parameters
	)

Decodes a command into transformation rules.

Parameters:

$name	Name of the command
$parameters	Array of parameters for the command

Returns:: An array with transformation rules.

Definition at line 1459 of file ezcodemapper.php.

eZCodeMapper::error	(	$	text,
		$	position = `false`
	)

Outputs error $text found in parsed file at position $position.

eZCodeMapper::executeCommandCode	(	&$	text,
		$	command,
		$	charsetName
	)

Executes custom PHP code for the command $command.

Parameters:

$charsetName The name of the charset the text will be in, this can be used to execute different code for different charsets.

Returns:: true if the command is supported, false otherwise.

Definition at line 1690 of file ezcodemapper.php.

eZCodeMapper::expandInheritance ( $ table ) [private]

Goes trough all entries in $table and if it finds identifier references it will fetch the table for that identifier and merge in the current one.

Returns:: The expanded table.

eZCodeMapper::extractUnicodeValue ( $ data ) [private]

Returns:: The first unicod value for the data entry $data.

eZCodeMapper::extractUnicodeValues ( $ data ) [private]

Returns:: The unicode values for the data entry $data.

eZCodeMapper::eZCodeMapper ( )

Constructor

eZCodeMapper::generateCharsetMappingTable	(	$	unicodeTable,
		$	charset
	)

Generates a mapping table for the character set $charset. This will mapping table will only work for that character set but will be much faster and be fed directly to the strtr() PHP function.

Returns:: the table or false if something failed.

Definition at line 1422 of file ezcodemapper.php.

eZCodeMapper::generateCommandCode	(	$	command,
		$	charsetName
	)

Generates PHP code for the command $command.

Parameters:

$charsetName The name of the charset the text will be in, this can be used to generate different code for different charsets.

Returns:: A string containing PHP code or false if not supported.

Definition at line 1545 of file ezcodemapper.php.

eZCodeMapper::generateMappingCode ( $ identifier )

Generates a unicode mapping table for idenfier $idenfier.

Parameters:

$identifier Is either a single identifier string or a an array with identifiers.

Returns:: The unicode mapping table for all defined identifiers

Definition at line 1403 of file ezcodemapper.php.

eZCodeMapper::generateSimpleMappingTable	(	$	table,
		$	allowedRanges
	)

Goes trough the mapping rules in the table $table and generates a simple mapping table which maps from one Unicode value to another (or array of values).

The generation uses backward and forward propagation of the defined mappings to get the proper end result of a given value.

Note:: This method can take a while if lots of rules are used

eZCodeMapper::isTranformationLoaded ( $ name )

Returns:: true if the transformation file is already loaded.

eZCodeMapper::loadTransformationFiles	(	$	currentCharset,
		$	transformationGroup
	)

Loads all transformation files defined in transform.ini to the current mapper. It will also load any transformations found in extensions.

Parameters:

$currentCharset	The name of the current charset in use. The caller must make sure this is not an alias by using eZCharsetInfo::realCharsetCode()
$transformationGroup	The transformation group which is currently used or `false` for none.

Definition at line 138 of file ezcodemapper.php.

eZCodeMapper::mapExistingCodes	(	$	unicodeMap,
		$	fromCode,
		$	toCode
	)		`[protected]`

Goes trough all to codes in the mapping table $unicodeMap and maps those that match $fromCode into $toCode.

Returns:: $unicodeMap

eZCodeMapper::mapOrdinals	(	$	table,
		$	ordinals
	)

Goes trough each ordinal in $ordinals and sees if there is mapping for it. If it is the mapping is applied and used as the new ordinal, if the mapping refers to an array it will be mapped recursively.
