Interface SerializationUnit

All Superinterfaces:

ContentHandler, Visitor

All Known Implementing Classes:

ContextObjectSerializationUnit, DefaultSerializationUnit, GhostElementSerializationUnit, TextSerializationUnit

public interface SerializationUnit
extends Visitor

W3C Node Serailization interface definition.

Implementations of this interface are applied to the content during the Serialisation phase.

This interface allows element targeted (by device, profile, DTD info etc) serialization code to be implemented. It gives control over how an element is "printed" to the target device.

Serialization Units are defined in the .cdrl file (in .cdrar file(s)) in the very same way as any other content delivery resource (Assembly Units, Processing Units, DTDs etc).

Implementations must be stateless in nature.

Only one Serialisation Unit is applied to each element. If more than one Serialization Unit is applicable to a given element, the most specific Serialization Unit is choosen. See SmooksResourceConfigurationSortComparator.

See Delivery Overview.
