Method Detail

checkSupported

public void checkSupported(NodeRef sourceNodeRef,
                           RenditionDefinition2 renditionDefinition,
                           String sourceMimetype,
                           long sourceSizeInBytes,
                           String contentUrl)

Description copied from interface: TransformClient

Checks the transformation required for the rendition is supported.

Specified by:

checkSupported in interface TransformClient

Parameters:

sourceNodeRef - the source node

renditionDefinition - which rendition to perform

sourceMimetype - the mometype of the source

sourceSizeInBytes - the size in bytes of the source

contentUrl - the url of the source (used in debug).

transform

public void transform(NodeRef sourceNodeRef,
                      RenditionDefinition2 renditionDefinition,
                      String user,
                      int sourceContentHashCode)

Description copied from interface: TransformClient

Requests an asynchronous transform and the subsequent linkage of that transform as a rendition. The call to this method MUST be proceeded by a successful call to TransformClient.checkSupported(NodeRef, RenditionDefinition2, String, long, String) in the SAME Thread.

Specified by:

transform in interface TransformClient

Parameters:

sourceNodeRef - the source node

renditionDefinition - which rendition to perform

user - that requested the transform.

sourceContentHashCode - the hash code of the source node's content URL. Used to check the transform result
