Class MTOMXMLStreamWriter

java.lang.Object
  org.apache.axiom.om.impl.MTOMXMLStreamWriter

All Implemented Interfaces:

javax.xml.stream.XMLStreamWriter

public class MTOMXMLStreamWriter
extends java.lang.Object
implements javax.xml.stream.XMLStreamWriter

MTOMXMLStreamWriter is an XML + Attachments stream writer. For the moment this assumes that transport takes the decision of whether to optimize or not by looking at whether the MTOM optimize is enabled & also looking at the OM tree whether it has any optimizable content.

Constructor Summary

MTOMXMLStreamWriter(java.io.OutputStream outStream, OMOutputFormat format)

MTOMXMLStreamWriter(java.io.OutputStream outStream, OMOutputFormat format, boolean preserveAttachments)
Creates a new MTOMXMLStreamWriter with specified encoding.

MTOMXMLStreamWriter(javax.xml.stream.XMLStreamWriter xmlWriter)

Method Summary

void	close()
void	flush() Flush is overridden to trigger the attachment serialization
java.lang.String	getCharSetEncoding() Returns the character set encoding scheme.
java.lang.String	getContentType()
java.lang.String	getMimeBoundary()
javax.xml.namespace.NamespaceContext	getNamespaceContext()
java.lang.String	getNextContentId()
OMOutputFormat	getOutputFormat() Get the output format used by this writer.
java.io.OutputStream	getOutputStream() Get the underlying OutputStream for this writer, if available.
java.lang.String	getPrefix(java.lang.String string)
java.lang.Object	getProperty(java.lang.String string)
java.lang.String	getRootContentId()
javax.xml.stream.XMLStreamWriter	getXmlStreamWriter()
java.lang.String	getXmlVersion()
boolean	isIgnoreXMLDeclaration()
boolean	isOptimized() Deprecated. Serialization code should use XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandler, String, boolean) or XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, org.apache.axiom.ext.stax.datahandler.DataHandlerProvider, String, boolean) to submit any binary content and let this writer decide whether the content should be written as base64 encoded character data or using xop:Include. This makes optimization entirely transparent for the caller and there should be no need to check if the writer is producing MTOM.
boolean	isOptimizedThreshold(OMText node) Deprecated. Serialization code should use XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandler, String, boolean) or XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandlerProvider, String, boolean) to submit any binary content and let this writer decide whether the content should be written as base64 encoded character data or using xop:Include. If this is not possible, then prepareDataHandler(DataHandler) should be used. All the aforementioned methods take into account the settings defined in OMOutputFormat to determine whether the binary data should be optimized or not. Therefore, there is not need for this method anymore.
java.lang.String	prepareDataHandler(javax.activation.DataHandler dataHandler) Prepare a DataHandler for serialization without using the DataHandlerWriter API.

Throws:

isOptimized

public boolean isOptimized()

Deprecated. Serialization code should use XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandler, String, boolean) or XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, org.apache.axiom.ext.stax.datahandler.DataHandlerProvider, String, boolean) to submit any binary content and let this writer decide whether the content should be written as base64 encoded character data or using xop:Include. This makes optimization entirely transparent for the caller and there should be no need to check if the writer is producing MTOM.

getContentType

public java.lang.String getContentType()

writeOptimized

public void writeOptimized(OMText node)

Deprecated. Serialization code should use XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandler, String, boolean) or XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandlerProvider, String, boolean) to submit any binary content and let this writer decide whether the content should be written as base64 encoded character data or using xop:Include. If this is not possible, then prepareDataHandler(DataHandler) should be used.

isOptimizedThreshold

public boolean isOptimizedThreshold(OMText node)

Deprecated. Serialization code should use XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandler, String, boolean) or XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandlerProvider, String, boolean) to submit any binary content and let this writer decide whether the content should be written as base64 encoded character data or using xop:Include. If this is not possible, then prepareDataHandler(DataHandler) should be used. All the aforementioned methods take into account the settings defined in OMOutputFormat to determine whether the binary data should be optimized or not. Therefore, there is not need for this method anymore.

prepareDataHandler

public java.lang.String prepareDataHandler(javax.activation.DataHandler dataHandler)

Prepare a DataHandler for serialization without using the DataHandlerWriter API. The method first determines whether the binary data represented by the DataHandler should be optimized or inlined. If the data should not be optimized, then the method returns null and the caller is expected to use writeCharacters(String) or writeCharacters(char[], int, int) to write the base64 encoded data to the stream. If the data should be optimized, then the method returns a content ID and the caller is expected to generate an xop:Include element referring to that content ID.

This method should only be used to integrate Axiom with third party libraries that support XOP. In all other cases, XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandler, String, boolean) or XMLStreamWriterUtils.writeDataHandler(XMLStreamWriter, DataHandlerProvider, String, boolean) should be used to write base64Binary values and the application code should never generate xop:Include elements itself.

Parameters:

dataHandler - the DataHandler that the caller intends to write to the stream

Returns:

the content ID that the caller must use in the xop:Include element or null if the base64 encoded data should not be optimized

setXmlStreamWriter

public void setXmlStreamWriter(javax.xml.stream.XMLStreamWriter xmlWriter)

getXmlStreamWriter

public javax.xml.stream.XMLStreamWriter getXmlStreamWriter()

getMimeBoundary

public java.lang.String getMimeBoundary()

getRootContentId

public java.lang.String getRootContentId()

getNextContentId

public java.lang.String getNextContentId()

getCharSetEncoding

public java.lang.String getCharSetEncoding()

Returns the character set encoding scheme. If the value of the charSetEncoding is not set then the default will be returned.

Returns:

Returns encoding.

setCharSetEncoding

public void setCharSetEncoding(java.lang.String charSetEncoding)

getXmlVersion

public java.lang.String getXmlVersion()

setXmlVersion

public void setXmlVersion(java.lang.String xmlVersion)

setSoap11

public void setSoap11(boolean b)

isIgnoreXMLDeclaration

public boolean isIgnoreXMLDeclaration()

setIgnoreXMLDeclaration

public void setIgnoreXMLDeclaration(boolean ignoreXMLDeclaration)

setDoOptimize

public void setDoOptimize(boolean b)

getOutputFormat

public OMOutputFormat getOutputFormat()

Get the output format used by this writer.

The caller should use the returned instance in a read-only way, i.e. he should not modify the settings of the output format. Any attempt to do so will lead to unpredictable results.

Returns:

the output format used by this writer

setOutputFormat

public void setOutputFormat(OMOutputFormat format)

getOutputStream

public java.io.OutputStream getOutputStream()
                                     throws javax.xml.stream.XMLStreamException

Get the underlying OutputStream for this writer, if available. This method allows a node (perhaps an OMSourcedElement) to write its content directly to the byte stream.

WARNING: This method should be used with extreme care. The caller must be prepared to handle the following issues:

• The caller must use the right charset encoding when writing to the stream.
• The caller should avoid writing byte order marks to the stream.
• The caller must be aware of the fact that a default namespace might have been set in the context where the byte stream is requested. If the XML data written to the stream contains unqualified elements, then the caller must make sure that the default namespace is redeclared as appropriate.

Returns:

the underlying byte stream, or null if the stream is not accessible

Throws:

javax.xml.stream.XMLStreamException

setFilter

public void setFilter(XMLStreamWriterFilter filter)

removeFilter

public XMLStreamWriterFilter removeFilter()
