Interface LowLevelFastInfosetStreamWriter

All Known Implementing Classes:

StAXDocumentSerializer

public interface LowLevelFastInfosetStreamWriter

Low level Fast Infoset stream writer.

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 ELEMENT 
                    endDocument
                 |  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.

Method Detail

initiateLowLevelWriting

void initiateLowLevelWriting()
                             throws javax.xml.stream.XMLStreamException

Initiate low level writing of an element fragment.

This method must be invoked before other low level method.

Throws:

javax.xml.stream.XMLStreamException

getNextElementIndex

int getNextElementIndex()

Get the next index to apply to an Element Information Item.

This will increment the next obtained index such that:

 i = w.getNextElementIndex();
 j = w.getNextElementIndex();
 i == j + 1;
 

Returns:

the index.

getNextAttributeIndex

int getNextAttributeIndex()

Get the next index to apply to an Attribute Information Item. This will increment the next obtained index such that:

 i = w.getNextAttributeIndex();
 j = w.getNextAttributeIndex();
 i == j + 1;
 

Returns:

the index.

getLocalNameIndex

int getLocalNameIndex()

Get the current index that was applied to an [local name] of an Element or Attribute Information Item.

Returns:

the index.

getNextLocalNameIndex

int getNextLocalNameIndex()

Get the next index to apply to an [local name] of an Element or Attribute Information Item. This will increment the next obtained index such that:

 i = w.getNextLocalNameIndex();
 j = w.getNextLocalNameIndex();
 i == j + 1;
 

Returns:

the index.
