public ContentTransformerHelper()

Method Detail

setMimetypeService

public void setMimetypeService(org.alfresco.service.cmr.repository.MimetypeService mimetypeService)

Helper setter of the mimetype service. This is not always required.

Parameters:

mimetypeService -

getMimetypeService

protected org.alfresco.service.cmr.repository.MimetypeService getMimetypeService()

Returns:

Returns the mimetype helper

setExplicitTransformations

public void setExplicitTransformations(java.util.List explicitTransformations)

Specifies transformations that are considered to be 'exceptional' so should be used in preference to other transformers that can perform the same transformation.

setSupportedTransformations

public void setSupportedTransformations(java.util.List supportedTransformations)

Restricts the transformations that may be performed even though the transformer may perform other transformations. An null value applies no additional restrictions. Even if a list is specified, the ContentTransformer.isTransformableMimetype(String, String, TransformationOptions) method will still be called.

setUnsupportedTransformations

public void setUnsupportedTransformations(java.util.List unsupportedTransformations)

Restricts the transformations that may be performed even though the transformer may claim to perform the transformations. An null value applies no additional restrictions. Even if a list is specified, the ContentTransformer.isTransformableMimetype(String, String, TransformationOptions) method will still be called.

getMimetype

protected java.lang.String getMimetype(org.alfresco.service.cmr.repository.ContentAccessor content)

Convenience to fetch and check the mimetype for the given content

Parameters:

content - the reader/writer for the content

Returns:

Returns the mimetype for the content

Throws:

org.alfresco.error.AlfrescoRuntimeException - if the content doesn't have a mimetype

isExplicitTransformation

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

Default implementation, override if need to extend logic

isSupportedTransformation

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