Class SwitchingSynchronousTransformClient

  • All Implemented Interfaces:
    SynchronousTransformClient
    @Deprecated
public class SwitchingSynchronousTransformClient
extends java.lang.Object
implements SynchronousTransformClient
    Deprecated.
    Request synchronous transforms. Used in refactoring deprecated code, which called Legacy transforms, so that it will first try a Local transform, falling back to Legacy if not available. Class provides the switch between Local and Legacy transforms.

        Description copied from interface: SynchronousTransformClient
        Works out if it is possible to transform content of a given source mimetype and size into a target mimetype given a list of actual transform option names and values (Strings) plus the data contained in the Transformer objects registered with this class.
        Specified by:
        isSupported in interface SynchronousTransformClient
        Parameters:
        sourceNodeRef - the NodeRef of the source content. Optional as it is only used in debug messages.
        sourceMimetype - the mimetype of the source content
        sourceSizeInBytes - the size in bytes of the source content. Ignored if negative.
        contentUrl - The url of the content. Optional as it is only used in debug messages.
        targetMimetype - the mimetype of the target
        actualOptions - the actual name value pairs available that could be passed to the Transform Service.
        transformName - (optional) name for the set of options and target mimetype. If supplied is used to cache results to avoid having to work out if a given transformation is supported a second time. The sourceMimetype and sourceSizeInBytes may still change. In the case of ACS this is the rendition name.
        Returns:
        true if it is supported.

        Description copied from interface: SynchronousTransformClient
        Requests a synchronous transform. Not used for renditions. The call to this method MUST be proceeded by a successful call to SynchronousTransformClient.isSupported(NodeRef, String, long, String, String, Map, String) in the SAME Thread.
        Specified by:
        transform in interface SynchronousTransformClient
        Parameters:
        reader - of the source content
        writer - to the target node's content
        actualOptions - the actual name value pairs available that could be passed to the Transform Service.
        transformName - (optional) name for the set of options and target mimetype. If supplied is used to cache results to avoid having to work out if a given transformation is supported a second time. The sourceMimetype and sourceSizeInBytes may still change. In the case of ACS this is the rendition name.
        sourceNodeRef - the source node
        Throws:
