Package com.sun.xml.txw2.output

Interface XmlSerializer

All Known Implementing Classes:

DomSerializer, DumpSerializer, SaxSerializer, StaxSerializer, StreamSerializer, TXWSerializer

public interface XmlSerializer

Low-level typeless XML writer driven from TypedXmlWriter.

Applications can use one of the predefined implementations to send TXW output to the desired location/format, or they can choose to implement this interface for custom output.

One XmlSerializer instance is responsible for writing one XML document.

Call Sequence

TXW calls methods on this interface in the following order:

 WHOLE_SEQUENCE := startDocument ELEMENT endDocument
 ELEMENT := beginStartTag writeXmlns* writeAttribute* endStartTag CONTENT endTag
 CONTENT := (text|ELEMENT)*
 

TXW maintains all the in-scope namespace bindings and prefix allocation. The XmlSerializer implementation should just use the prefix specified.

Method Detail

startDocument

void startDocument()

The first method to be called.

beginStartTag

void beginStartTag(java.lang.String uri,
                   java.lang.String localName,
                   java.lang.String prefix)

Begins writing a start tag.

Parameters:

uri - the namespace URI of the element. Can be empty but never be null.

prefix - the prefix that should be used for this element. Can be empty, but never null.

writeAttribute

void writeAttribute(java.lang.String uri,
                    java.lang.String localName,
                    java.lang.String prefix,
                    java.lang.StringBuilder value)

Writes an attribute.

Parameters:

value - The value of the attribute. It's the callee's responsibility to escape special characters (such as <, >, and &) in this buffer.

uri - the namespace URI of the attribute. Can be empty but never be null.

prefix - the prefix that should be used for this attribute. Can be empty, but never null.

writeXmlns

void writeXmlns(java.lang.String prefix,
                java.lang.String uri)

Writes a namespace declaration.

Parameters:

uri - the namespace URI to be declared. Can be empty but never be null.

prefix - the prefix that is allocated. Can be empty but never be null.

endStartTag

void endStartTag(java.lang.String uri,
                 java.lang.String localName,
                 java.lang.String prefix)

Completes the start tag.

Parameters:

uri - the namespace URI of the element. Can be empty but never be null.

prefix - the prefix that should be used for this element. Can be empty, but never null.

endTag

void endTag()

Writes an end tag.

text

void text(java.lang.StringBuilder text)

Writes PCDATA.

Parameters:

text - The character data to be written. It's the callee's responsibility to escape special characters (such as <, >, and &) in this buffer.

cdata

void cdata(java.lang.StringBuilder text)

Writes CDATA.

comment

void comment(java.lang.StringBuilder comment)

Writes a comment.

Throws:

java.lang.UnsupportedOperationException - if the writer doesn't support writing a comment, it can throw this exception.

endDocument

void endDocument()

The last method to be called.

flush

void flush()

Flush the buffer. This method is called when applications invoke TypedXmlWriter.commit(boolean) method. If the implementation performs any buffering, it should flush the buffer.
