Method Summary

protected org.xml.sax.ContentHandler	getContentHandler(java.lang.String targetMimeType, java.io.Writer output) Returns an appropriate Tika ContentHandler for the requested content type.
protected org.apache.tika.parser.Parser	getParser() Returns the correct Tika Parser to process the document.
boolean	isExplicitTransformation(java.lang.String sourceMimetype, java.lang.String targetMimetype, TransformationOptions options) Make sure we win over openoffice when it comes to producing HTML
boolean	isTransformable(java.lang.String sourceMimetype, long sourceSize, java.lang.String targetMimetype, TransformationOptions options) Can we do the requested transformation via Tika? We support transforming to HTML, XML, Text or CSV
boolean	isTransformable(java.lang.String sourceMimetype, java.lang.String targetMimetype, TransformationOptions options) Deprecated. This method should no longer be called as the overloaded method that calls it has been overridden.

Method Detail

getParser

protected org.apache.tika.parser.Parser getParser()

Description copied from class: TikaPoweredContentTransformer

Returns the correct Tika Parser to process the document. If you don't know which you want, use TikaAutoContentTransformer which makes use of the Tika auto-detection.

getParser in class TikaPoweredContentTransformer

isTransformable

public boolean isTransformable(java.lang.String sourceMimetype,
                               long sourceSize,
                               java.lang.String targetMimetype,
                               TransformationOptions options)

Can we do the requested transformation via Tika? We support transforming to HTML, XML, Text or CSV

Specified by:

isTransformable in interface ContentTransformer

Overrides:

isTransformable in class TikaPoweredContentTransformer

Parameters:

sourceMimetype - the source mimetype

sourceSize - the size (bytes) of the source. If negative it is unknown.

targetMimetype - the target mimetype

options - the transformation options

Returns:

boolean true if this content transformer can satify the mimetypes and options specified, false otherwise

isTransformable

public boolean isTransformable(java.lang.String sourceMimetype,
                               java.lang.String targetMimetype,
                               TransformationOptions options)

Deprecated. This method should no longer be called as the overloaded method that calls it has been overridden.

Specified by:

isTransformable in interface ContentTransformer

Overrides:

isTransformable in class TikaPoweredContentTransformer

isExplicitTransformation

public boolean isExplicitTransformation(java.lang.String sourceMimetype,
                                        java.lang.String targetMimetype,
                                        TransformationOptions options)

Make sure we win over openoffice when it comes to producing HTML

Specified by:

isExplicitTransformation in interface ContentTransformer

Overrides:

isExplicitTransformation in class ContentTransformerHelper

Parameters:

sourceMimetype - the source mimetype

targetMimetype - the target mimetype

options - the transformation options

Returns:

boolean true if it is an explicit transformation, flase otherwise

getContentHandler

protected org.xml.sax.ContentHandler getContentHandler(java.lang.String targetMimeType,
                                                       java.io.Writer output)
                                                throws javax.xml.transform.TransformerConfigurationException

Description copied from class: TikaPoweredContentTransformer

Returns an appropriate Tika ContentHandler for the requested content type. Normally you'll let this work as default, but if you need fine-grained control of how the Tika events become text then override and supply your own.

Overrides:

getContentHandler in class TikaPoweredContentTransformer

Throws:

javax.xml.transform.TransformerConfigurationException
