public interface LowLevelFastInfosetStreamWriter
This interface provides additional stream-based serialization methods for the case where an application is in specific control of the serialization process and has the knowledge to call the LowLevel methods in the required order.
For example, the application may be able to perform efficient information to indexing mapping and to provide certain information in UTF-8 encoded form.
These methods may be used in conjuction with XMLStreamWriter
as long as an element fragment written using the efficient streaming methods
are self-contained and no sub-fragment is written using methods from
XMLStreamWriter
.
The required call sequence is as follows:
CALLSEQUENCE :=startDocument
initiateLowLevelWriting ELEMENTendDocument
| initiateLowLevelWriting ELEMENT // for fragment ELEMENT := writeLowLevelTerminationAndMark NAMESPACES? ELEMENT_NAME ATTRIBUTES? writeLowLevelEndStartElement CONTENTS writeLowLevelEndElement NAMESPACES := writeLowLevelStartNamespaces writeLowLevelNamespace* writeLowLevelEndNamespaces ELEMENT_NAME := writeLowLevelStartElementIndexed | writeLowLevelStartNameLiteral | writeLowLevelStartElement ATTRUBUTES := writeLowLevelStartAttributes (ATTRIBUTE_NAME writeLowLevelAttributeValue)* ATTRIBUTE_NAME := writeLowLevelAttributeIndexed | writeLowLevelStartNameLiteral | writeLowLevelAttribute CONTENTS := (ELEMENT | writeLowLevelText writeLowLevelOctets)*
Some methods defer to the application for the mapping of information to indexes.

This method must be invoked before other low level method.
int getNextElementIndex()
This will increment the next obtained index such that:
i = w.getNextElementIndex(); j = w.getNextElementIndex(); i == j + 1;
int getNextAttributeIndex()
i = w.getNextAttributeIndex(); j = w.getNextAttributeIndex(); i == j + 1;
int getLocalNameIndex()
int getNextLocalNameIndex()
i = w.getNextLocalNameIndex(); j = w.getNextLocalNameIndex(); i == j + 1;
