org.alfresco.repo.content.transform.StringExtractingContentTransformer

All Implemented Interfaces:

ContentWorker, ContentTransformer, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware

@Deprecated
public class StringExtractingContentTransformer
extends AbstractRemoteContentTransformer

Deprecated.

The transformations code is being moved out of the codebase and replaced by the new async RenditionService2 or other external libraries.

Converts any textual format to plain text.

The transformation is sensitive to the source and target string encodings.

Method Detail

isTransformableMimetype

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

Deprecated.

Gives a high reliability for all translations from text/sometype to text/plain. As the text formats are already text, the characters are preserved and no actual conversion takes place.

Extraction of text from binary data is wholly unreliable.

Specified by:

isTransformableMimetype in interface ContentTransformer

Overrides:

isTransformableMimetype in class AbstractContentTransformerLimits

Parameters:

sourceMimetype - the source mimetype

targetMimetype - the target mimetype

options - the transformation options

Returns:

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

getComments

public java.lang.String getComments(boolean available)

Deprecated.

Description copied from class: ContentTransformerHelper

Overridden to supply a comment or String of commented out transformation properties that specify any (hard coded or implied) supported transformations. Used when providing a list of properties to an administrators who may be setting other transformation properties, via JMX. Consider overriding if {link AbstractContentTransformerLimits.isTransformableMimetype(String, String, TransformationOptions) or ContentTransformerWorker.isTransformable(String, String, TransformationOptions) have been overridden. See ContentTransformerHelper.getCommentsOnlySupports(List, List, boolean) which may be used to help construct a comment.

Specified by:

getComments in interface ContentTransformer

Overrides:

getComments in class ContentTransformerHelper

Parameters:

available - indicates if the transformer has been registered and is available to be selected. false indicates that the transformer is only available as a component of a complex transformer.

Returns:

one line per property. The simple transformer name is returned by default as a comment.

getLogger

protected org.apache.commons.logging.Log getLogger()

Deprecated.

Specified by:

getLogger in class AbstractRemoteContentTransformer

transformLocal

public void transformLocal(org.alfresco.service.cmr.repository.ContentReader reader,
                           org.alfresco.service.cmr.repository.ContentWriter writer,
                           TransformationOptions options)
                    throws java.lang.Exception

Deprecated.

Text to text conversions are done directly using the content reader and writer string manipulation methods.

Extraction of text from binary content attempts to take the possible character encoding into account. The text produced from this will, if the encoding was correct, be unformatted but valid.

Specified by:

transformLocal in class AbstractRemoteContentTransformer

Throws:

java.lang.Exception

transformRemote

protected void transformRemote(RemoteTransformerClient remoteTransformerClient,
                               org.alfresco.service.cmr.repository.ContentReader reader,
                               org.alfresco.service.cmr.repository.ContentWriter writer,
                               TransformationOptions options,
                               java.lang.String sourceMimetype,
                               java.lang.String targetMimetype,
                               java.lang.String sourceExtension,
                               java.lang.String targetExtension,
                               java.lang.String targetEncoding)
                        throws java.lang.Exception

Deprecated.

Specified by:

transformRemote in class AbstractRemoteContentTransformer

Throws:

java.lang.Exception
