Method Detail

set

public <T> void set(Class<T> key,
                    T value)

Adds the given value to the context as an implementation of the given interface.

Parameters:

key - the interface implemented by the given value

value - the value to be added, or null to remove

get

public <T> T get(Class<T> key)

Returns the object in this context that implements the given interface.

Parameters:

key - the interface implemented by the requested object

Returns:

the object that implements the given interface, or null if not found

get

public <T> T get(Class<T> key,
                 T defaultValue)

Returns the object in this context that implements the given interface, or the given default value if such an object is not found.

Parameters:

key - the interface implemented by the requested object

defaultValue - value to return if the requested object is not found

Returns:

the object that implements the given interface, or the given default value if not found

getXMLReader

public XMLReader getXMLReader()
                       throws TikaException

Returns the XMLReader specified in this parsing context. If a reader is not explicitly specified, then one is created using the specified or the default SAX parser.

Returns:

XMLReader

Throws:

TikaException

Since:

Apache Tika 1.13

See Also:

getSAXParser()

getSAXParser

public SAXParser getSAXParser()
                       throws TikaException

Returns the SAX parser specified in this parsing context. If a parser is not explicitly specified, then one is created using the specified or the default SAX parser factory. Consider using XMLReaderUtils#parseSAX(InputStream, DefaultHandler, ParseContext) for more efficient reuse of SAXParsers.

Returns:

SAX parser

Throws:

TikaException - if a SAX parser could not be created

Since:

Apache Tika 0.8

See Also:

getSAXParserFactory()

getSAXParserFactory

public SAXParserFactory getSAXParserFactory()

Returns the SAX parser factory specified in this parsing context. If a factory is not explicitly specified, then a default factory instance is created and returned. The default factory instance is configured to be namespace-aware, not validating, and to use secure XML processing.

Returns:

SAX parser factory

Since:

Apache Tika 0.8

getDocumentBuilder

public DocumentBuilder getDocumentBuilder()
                                   throws TikaException

Returns the DOM builder specified in this parsing context. If a builder is not explicitly specified, then a builder instance is created and returned. The builder instance is configured to apply an XMLReaderUtils.IGNORING_SAX_ENTITY_RESOLVER, and it sets the ErrorHandler to null. Consider using XMLReaderUtils.buildDOM(InputStream, ParseContext) instead for more efficient reuse of document builders.

Returns:

DOM Builder

Throws:

TikaException

Since:

Apache Tika 1.13

getXMLInputFactory

public XMLInputFactory getXMLInputFactory()

Returns the StAX input factory specified in this parsing context. If a factory is not explicitly specified, then a default factory instance is created and returned. The default factory instance is configured to be namespace-aware and to apply reasonable security using the XMLReaderUtils.IGNORING_STAX_ENTITY_RESOLVER.

Returns:

StAX input factory

Since:

Apache Tika 1.13

getTransformer

public Transformer getTransformer()
                           throws TikaException

Returns the transformer specified in this parsing context.

If a transformer is not explicitly specified, then a default transformer instance is created and returned. The default transformer instance is configured to to use secure XML processing.

Returns:

Transformer

Throws:

TikaException - when the transformer can not be created

Since:

Apache Tika 1.17
