    alfresco-pdf-renderer ${source} ${target}
 

Parameters:

executer - the system command executer

setRemoteTransformerClient

public void setRemoteTransformerClient(RemoteTransformerClient remoteTransformerClient)

Sets the optional remote transformer client which will be used in preference to a local command if available.

Parameters:

remoteTransformerClient - may be null;

setCheckCommand

public void setCheckCommand(RuntimeExec checkCommand)

Sets the command that must be executed in order to retrieve version information from the executable and thus test that the executable itself is present.

Parameters:

checkCommand - command executer to retrieve version information

                               String targetMimetype,
                               TransformationOptions options)

Description copied from interface: ContentTransformerWorker

Unlike ContentTransformer.isTransformable(String, String, TransformationOptions) should not include the transformer name, as that is added by the ContentTransformer in the parent context.

Specified by:

transform

public void transform(ContentReader reader,
                      ContentWriter writer,

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 ContentTransformerWorker

Overrides:

getComments in class ContentTransformerHelper

Parameters:
