public class ContentType

extends Object

The static fields of this class are used to identify what type of data is being processed by a Stylus Studio XML Pipeline. When a node in a pipeline generates output data, the data object will be associated with a ContentType value. That value is used as a hint for subsequent pipeline nodes to interpret the data properly. For example, if a data object has ContentType.CONTENT_TEXT, then subsequent nodes will avoid parsing the data as xml data. This is, however, only a hint. If, for example, an XQuery node is required to bind an input data object to an external variable which is declared to be a document-node(), then the XQuery node will attempt to parse the data object to create a DOM, not matter which ContentType the data object is associated with.
If an XML Pipeline is embedded in a java program using the interface PipelineOperation, the caller program can bind data objects to the pipeline. The caller passes one of the static fields of this class when binding the input data. The pipeline will then associate the data object with the specified content type.
