Interface ExtractorRegistry

All Known Implementing Classes:

DefaultExtractorRegistry, ExtractorRegistryImpl

public interface ExtractorRegistry

An ExtractorRegistry serves as a central registry for registering and obtaining ExtractorFactories.

Method Summary

void	add(ExtractorFactory factory) Adds an ExtractorFactory to this registry.
void	add(FileExtractorFactory factory) Adds a file extractor factory to this registry.
Set	get(String mimeType) Deprecated. Use getExtractorFactories instead. After the introduction of FileExtractorFactories the semantics of this method may have become unclear. It returns normal stream-based extractor factories. The result is the same as getExtractorFactories(java.lang.String)
Set	getAll() Deprecated. Use getAllExtractorFactories instead. After the introduction of FileExtractorFactories the semantics of this method may have become unclear. It returns normal stream-based extractor factories. The result is the same as getAllExtractorFactories()
Set	getAllExtractorFactories() Returns all ExtractorFactories registered in this ExtractorRegistry.
Set	getAllFileExtractorFactories() Returns all FileExtractorFactories registered in this ExtractorRegistry.
Set	getExtractorFactories(String mimeType) Returns all ExtractorFactories that support the specified MIME type.
Set	getFileExtractorFactories(String mimeType) Returns all FileExtractorFactories that support the specified MIME type.
void	remove(ExtractorFactory factory) Removes an ExtractorFactory from this registry.
void	remove(FileExtractorFactory factory) Remove a FileExtractorFactory from this registry.
