  • All Implemented Interfaces:
    SynchronousTransformClient, org.springframework.beans.factory.InitializingBean
    public class LocalSynchronousTransformClient
extends Object
implements SynchronousTransformClient, org.springframework.beans.factory.InitializingBean

                           NodeRef sourceNodeRef)
        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. Ideally, just call the transform method and catch the UnsupportedTransformationException to avoid extra work.
        Specified by:
        isSupported in interface SynchronousTransformClient
        Parameters:
        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.
        sourceNodeRef - (optional) NodeRef of the source content. Only used in debug messages.
        Returns:
        true if it is supported.

        Requests a synchronous transform.

        Parameters:
