the class ScriptNode method createThumbnail.

/**
 * Creates a thumbnail for the content property of the node.
 *
 * The thumbnail name corresponds to pre-set thumbnail details stored in the
 * repository.
 *
 * If the thumbnail is created asynchronously then the result will be null and creation
 * of the thumbnail will occure at some point in the background.
 *
 * If foce param specified system.thumbnail.generate is ignoring. Could be used for preview creation
 *
 * @param  thumbnailName    the name of the thumbnail
 * @param  async            indicates whether the thumbnail is create asynchronously or not
 * @param  force            ignore system.thumbnail.generate=false
 * @return ScriptThumbnail  the newly create thumbnail node or null if async creation occures
 *
 * @deprecated The async flag in the method signature will not be applicable as all of
 * the future transformations will be asynchronous
