ListParserConstants	Token literal values and constants.
Transformer	Interface for transformations.

Class Summary

AbstractCommandStringTransformer	If you want to transform a Reader stream by the use of an external command, than you can extend this class.
Asciifier	Transforms strings to ascii strings.
Base64	Code taken from "http://www.source-code.biz/snippets/java/2.htm"
BufferedReaderTransformer
BufferedReaderTransformer.Status
ByteArrayToCharTransformer	You need only to implement transform(byte[]) you have the simplest kind of transformer (which is not 'streamable').
ByteCharTransformer	A CharTransformer which wraps a ByteToCharTransformer.
ByteTransformerLink	A Runnable implementation to perform a ByteTransformation between an InputStream and an OutputStream.
Censor	Replaces certain 'forbidden' words by something more decent.
ChainedCharTransformer	A CharTransformer which wraps N other CharTransformers, and links them with N - 1 new Threads, effectively working as a 'chained' transformer.
CharTransformerLink	A Runnable implementation to perform a CharTransform between a Reader and a Writer.
ChunkedTransformer<P>	A chunked transformer is a transformer that transforms on a 'chunk by chunk' base.
Config	Describes what encoding is configured.
ConfigurableReaderTransformer	Some Transformers implement more than one transformation.
ConfigurableStringTransformer	Some Transformers implement more than one transformation.
CopyCharTransformer	This is the character transformer which does not actually transform anything, it just copies the reader to the writer.
CP1252Surrogator	Surrogates the Windows CP1252 characters which are not valid ISO-8859-1.
DiacriticsRemover	This transformer removes all diacritics from the characters of a string.
Figlet	An escaper based on the amusing 'figlet' tool, which is available on some system.
Graphviz	Wraps the tools of graphviz into an MMBase 'chartransformer'.
Hex	Encode a bytearray to a string by converting every byte to a hexadecimal (00 - FF) representation, and decode the other way around.
Identifier	Transforms strings to identifiers, replacing punctuation and whitespace with underscores.
InputStreamTransformer	Abstract implementation of ByteTransformer.
InverseCharTransformer	Turns a Transformer around.
Iso1	Provides the (unmodifiable) map 'iso2htmlMappings'
Javascript	Encodings related Javascript It can escape single quotes, by replacing them by \\', as is needed in document.write actions.
Latin3Surrogator	The ISO-8859-3 ('South European') unibyte encoding is used for languages like maltese and esperanto.
LinkFinder	Finds links in the Character String, and makes them 'clickable' for HTML (using a-tags).
ListParser
ListParserTokenManager	Token Manager.
LoggerCharTransformer	This is the character transformer is like CopyCharTransformer, but it logs everything that it sees too.
LowerCaser	Transforms to lowercase
MD5	Do MD5 encoding.
MD5.MD5Implementation
Perl	And yet another rather idiotic type of Transformer.
RadixTransformer	This straight-forward transformer wraps Long.toString(long, int) and Long.parseLong(String, int).
ReaderTransformer	You need only to implement transform(Reader, Writer) you have the simplest kind of tranformer (which is 'streamable').
RegexpReplacer	Finds regexps in the Character String, and replaces them.
RomanTransformer	Static utilities to deal with roman numbers, and non static functions to transform strings representing decimal numbers to roman numbers and back.
Rot13	Rot13 implementation.
Rot5	Rot5 implementation.
SimpleCharStream	An implementation of interface CharStream, where the stream is assumed to contain only ASCII characters (without unicode processing).
Sitestat	Transforms the input to the characters which are allowed in Sitestat keys for page statistics, being: "A-Z, a-z, 0-9, - .
SpaceReducer	Replace 1 or more spaces by 1 space, and 1 or more newlines by 1 newline.
SpaceReducer.SpaceReducerStatus
SpaceReducer.Tag	this is a helper class that can check if a tag was opened or closed in a line of text It first removes all bodyless versions of the tag from the line, and then counts all opening and closing occurrences of the tag.
SpaceRemover	Replace 1 or white space by 1 space, and all spaces on the begin and end.
SpaceSwallower	Swallows all spaces.
Sql	Encodings related to Sql.
StringTransformer	You need only to implement transform(String) you have the simplest kind of tranformer (which is not 'streamable').
Swallower	This tranformer is the equivalent of piping to /dev/null
TabToSpacesTransformer	Replace every tab by n spaces.
TagStripper
TagStripper.ParserGetter
TagStripper.Tag
TagStripper.TagCheck
Token	Describes the input token stream.
TransformingOutputStream	A Filtering OutputStream based on ByteTransformers.
TransformingReader	A Filtering Reader based on CharTransformers.
TransformingWriter	A Filtering Writer based on CharTransformers.
Trimmer	Trims leading and trailing white space.
UnicodeEscaper	To escape from and to 'java' like unicode escaping.
UpperCaser	A 'hello world' for CharTransformers.
Url	Encodings related to URL's.
UrlEscaper	Escapes and Unescapes undesirable characters using % (URLEncoding) Contrary to java.net.URLEncoder, it does not encode '+'.
Xml	Transformations related to escaping in XML.
XmlEntities	Any non-ASCII character will be replaced by an XML-entity.
XmlField	XMLFields in MMBase.
XmlField.ErrorHandler
YUICSSCompressor	CSS compressor based on YUI Library
YUIJavaScriptCompressor	Javascript compressor based on YUI Library

Enum Summary

TagStripper.State

UnknownCodingException	Class UnknownCodingException
XmlField.FormatException

Error Summary

TokenMgrError

Token Manager Error.

Package org.mmbase.util.transformers Description

Transformers define tranformations of Strings, byte arrays and streams. Transformers are devided in three species. CharTransformers which transform some String to another String (or Reader to a Writer). Then there are transformation which take a byte array (or an InputStream) and transform that to a String (or a Writer), these are called ByteToCharTransformers. And the last type are are the ByteTranformers, which tranform a byte array to another byte array (or an InputStream to an OutputStream). All Transformers can be specialized to ConfigurableTransformers. Several Abstract implemenations are present too. E.g. the ReaderTransformer is nearly a complete CharTransformer, only the function wich pipes a Reader to a Writer is abstract. StringTransformer is a CharTransformer which' only abstract function is the one taking a String argument.
