Uses of Filter in de.unidu.is.text

Classes in de.unidu.is.text that implement Filter

class	AbstractFilter This is an abstract filter implementation which allows for chaining filters.
class	AbstractSingleItemFilter This is an abstract filter implementation which converts every object into exactly one object (or into null), and which allows for chaining filters.
class	CodecSoundexFilter This filter converts a specified string into its soundex representation, using code from Apache Jakarta Commons Codec.
class	CounterFilter This filter counts occurences of objects, and returns a list of object-frequency pairs.
class	GermanStemmerFilter This filter converts a specified German string into stemmed version.
class	HTMLFilter This filter extracts all text from a specified HTML string, and returns the text content in a single string.
class	LowercaseFilter This filter converts a specified string into lowercase.
class	ParserFilter This filter splits a string into tokens (by converting all non-letter characters are converted into whitespaces, splitting the resulting string is split into tokens with whitespaces as token boundaries, and considering only tokens with at least 3 characters), converts the tokens into lowercase, computes the stems of the tokens, and removed stopwords.
class	SoundexFilter This filter converts a specified string into its soundex representation.
class	StemmerFilter This filter converts a specified string into stemmed version.
class	StopwordFilter This filter is used for removing stop words.
class	TokenSplitterFilter This filter splits a string into tokens.
class	UntagFilter This filter removes XML/HTML tags from a specified string.
class	WordConcatenatorFilter This filter concatenes all values together (separated by a space).
class	WordSetConcatenatorFilter This filter concatenes all values together (separated by a space), where each word only occurs once.
class	WordSplitterFilter This filter splits a string into tokens.

Fields in de.unidu.is.text declared as Filter

protected Filter	AbstractFilter.nextFilter The next filter in the filter chain.
protected Filter	WordConcatenatorFilter.nextFilter The next filter in the filter chain.
protected Filter	WordSetConcatenatorFilter.nextFilter The next filter in the filter chain.
