java.lang.Object

org.alfresco.repo.content.transform.ContentTransformerRegistry

@AlfrescoPublicApi
public class ContentTransformerRegistry
extends Object

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.

Method Detail

addTransformer

public void addTransformer(ContentTransformer transformer)

Registers an individual transformer that can be queried to check for applicability.

Parameters:

transformer - a content transformer

addComponentTransformer

public void addComponentTransformer(ContentTransformer transformer)

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

Parameters:

transformer - a content transformer

transformer - to be removed.

getTransformers

public List<ContentTransformer> getTransformers()

Returns:

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

getAllTransformers

public List<ContentTransformer> getAllTransformers()

Returns:

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

getTransformer

public ContentTransformer getTransformer(String transformerName)

Returns a transformer identified by name.

Throws:

IllegalArgumentException - if transformerName is not found.

getTransformer

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

Deprecated. use overloaded version with sourceSize parameter.

getTransformer

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.

getActiveTransformers

public List<ContentTransformer> getActiveTransformers(String sourceMimetype,
                                                      long sourceSize,
                                                      String targetMimetype,
