Method Detail

init

public static void init()

Registers all parsers from extension points

parse

public static String parse(InputStream input,
                           String filename,
                           String encoding,
                           Locale locale,
                           long tenantId,
                           Document document,
                           String fileVersion)

Gets the proper parser and parse the given content

Parameters:

input - the input contents as stream

filename - name of the file

encoding - encoding of the stream

locale - the locale

tenantId - identifier of the tenant

document - the document the file belongs to (optional)

fileVersion - the file version being processed (optional)

Returns:

the text extracted from the input

getParser

public static Parser getParser(String filename)

Method containing the lookup logic

Parameters:

filename - name of the file

Returns:

the right parser for the given file name

getExtensions

public static Set<String> getExtensions()

getParsers

public static Map<String,Parser> getParsers()

setAliases

public static void setAliases(String ext,
                              String[] aliases)

Adds new aliases for the specified extension.

Each alias is saved as property parser.alias.<ext>
example: parser.alias.odt = test, acme
In this case an extension 'test' will be treated as 'odt'

Parameters:

ext - Must be one of the registered extensions

aliases - Array of extension aliases (eg. test, acme ...)
