Method Detail

doInitialize

protected void doInitialize()

This method performs the actual initialization. It is called when AbstractComponent.initialize() is invoked for the first time.
ATTENTION:
When you override this method from a sub-class you need to do a super.AbstractComponent.doInitialize().

Overrides:

doInitialize in class AbstractLoggableComponent

getGenericParser

public ContentParser getGenericParser()

This method gets a generic parser that can be used as fallback if no specific parser is available.

Specified by:

getGenericParser in interface ContentParserService

Returns:

the generic parser.

setContentParsers

@Inject
public void setContentParsers(List<AbstractContentParser> contentParsers)

Parameters:

contentParsers - is the contentParsers to set

getParser

public ContentParser getParser(String key)

This method gets the parser for the given key.

Specified by:

getParser in interface ContentParserService

Parameters:

key - is the key identifying the requested parser. You can use the extension or the mimetype of the content you want to parse.

Returns:

the parser for the given key or the generic parser if no specific parser is available (check ContentParser.getExtension() for null to figure out).

See Also:

ContentParser.getPrimaryKeys(), ContentParser.getSecondaryKeys()

addParser

public void addParser(ContentParser parser,
                      String... keys)

This method registers the given parser for the given extension.

Parameters:

parser - is the parser to register.

keys - are the extensions the parser will be associated with.
