Class ContentTransformerRegistry

org.alfresco.repo.content.transform.ContentTransformerRegistry

@org.alfresco.api.AlfrescoPublicApi
public class ContentTransformerRegistry

Holds and provides the most appropriate content transformer for a particular source and target mimetype transformation request.

The transformers themselves are used to determine the applicability of a particular transformation.

The actual selection of a transformer is done by the injected TransformerSelector.

Constructor Summary
ContentTransformerRegistry(TransformerSelector transformerSelector)

Method Summary
void	addComponentTransformer(ContentTransformer transformer) Records a transformer that can NOT be queried for applicability, but may be included as a component of complex transformers.
void	addTransformer(ContentTransformer transformer) Registers an individual transformer that can be queried to check for applicability.
List<ContentTransformer>	getActiveTransformers(String sourceMimetype, long sourceSize, String targetMimetype, TransformationOptions options)
List<ContentTransformer>	getAllTransformers()
ContentTransformer	getTransformer(String transformerName) Returns a transformer identified by name.
ContentTransformer	getTransformer(String sourceMimetype, long sourceSize, String targetMimetype, TransformationOptions options) Gets the best transformer possible.
ContentTransformer	getTransformer(String sourceMimetype, String targetMimetype, TransformationOptions options) Deprecated. use overloaded version with sourceSize parameter.
List<ContentTransformer>	getTransformers()
void	removeTransformer(ContentTransformer transformer) Removes a dynamically created transformer.

Records a transformer that can NOT be queried for applicability, but may be included as a component of complex transformers.

transformer - a content transformer

public void removeTransformer(ContentTransformer transformer)

Removes a dynamically created transformer.

transformer - to be removed.

public List<ContentTransformer> getTransformers()

a list of transformers that may be queried to check for applicability.

public List<ContentTransformer> getAllTransformers()

a list of all transformers, including those that only exist as a component of another transformer.

public ContentTransformer getTransformer(String transformerName)

Returns a transformer identified by name.

IllegalArgumentException - if transformerName is not found.

public ContentTransformer getTransformer(String sourceMimetype,
String targetMimetype,
TransformationOptions options)

Deprecated. use overloaded version with sourceSize parameter.

public ContentTransformer getTransformer(String sourceMimetype,
                                         long sourceSize,
                                         String targetMimetype,
                                         TransformationOptions options)

Gets the best transformer possible. This is a combination of the most reliable and the most performant transformer.
