          extended byorg.apache.axis.message.SOAPMessageAxisImpl
              extended byorg.apache.axis.Message
All Implemented Interfaces:
Serializable
public class Message
extends SOAPMessageAxisImpl
implements Serializable

A complete SOAP (and/or XML-RPC, eventually) message. Includes both the root part (as a SOAPPart), and zero or more MIME attachments (as AttachmentParts).

Eventually should be refactored to generalize SOAPPart for multiple protocols (XML-RPC?).

Constructor Detail

Message

public Message(Object initialContents,
               boolean bodyInStream)
Construct a Message, using the provided initialContents as the contents of the Message's SOAPPart.

Eventually, genericize this to return the RootPart instead, which will have some kind of EnvelopeFactory to enable support for things other than SOAP. But that all will come later, with lots of additional refactoring.

Parameters:
initialContents - may be String, byte[], InputStream, SOAPEnvelope, or AxisFault.
bodyInStream - is true if initialContents is an InputStream containing just the SOAP body (no SOAP-ENV).

Message

public Message(Object initialContents,
               boolean bodyInStream,
               javax.xml.soap.MimeHeaders headers)
Construct a Message, using the provided initialContents as the contents of the Message's SOAPPart.

Eventually, genericize this to return the RootPart instead, which will have some kind of EnvelopeFactory to enable support for things other than SOAP. But that all will come later, with lots of additional refactoring.

Parameters:
initialContents - may be String, byte[], InputStream, SOAPEnvelope, or AxisFault.
bodyInStream - is true if initialContents is an InputStream containing just the SOAP body (no SOAP-ENV).
headers - Mime Headers.

Message

public Message(Object initialContents,
               MimeHeadersImpl headers)
Construct a Message, using the provided initialContents as the contents of the Message's SOAPPart.

Eventually, genericize this to return the RootPart instead, which will have some kind of EnvelopeFactory to enable support for things other than SOAP. But that all will come later, with lots of additional refactoring.

Parameters:
initialContents - may be String, byte[], InputStream, SOAPEnvelope, or AxisFault.
headers - Mime Headers.

Message

public Message(Object initialContents,
               boolean bodyInStream,
               String contentType,
               String contentLocation)
Construct a Message, using the provided initialContents as the contents of the Message's SOAPPart.

Eventually, genericize this to return the RootPart instead, which will have some kind of EnvelopeFactory to enable support for things other than SOAP. But that all will come later, with lots of additional refactoring.

Parameters:
initialContents - may be String, byte[], InputStream, SOAPEnvelope, or AxisFault
bodyInStream - is true if initialContents is an InputStream containing just the SOAP body (no SOAP-ENV)
contentType - this if the contentType has been already determined (as in the case of servlets)
contentLocation - the location of the content

getContentDescription

public String getContentDescription()
Retrieves a description of this SOAPMessage object's content.

Overrides:
getContentDescription in class SOAPMessageImpl
Returns:
a String describing the content of this message or null if no description has been set
See Also:

setContentDescription

public void setContentDescription(String description)
Sets the description of this SOAPMessage object's content with the given description.

Overrides:
setContentDescription in class SOAPMessageImpl
Parameters:
description - a String describing the content of this message
See Also:
getContentDescription()

saveChanges

public void saveChanges()
                 throws javax.xml.soap.SOAPException
Updates this SOAPMessage object with all the changes that have been made to it. This method is called automatically when a message is sent or written to by the methods ProviderConnection.send, SOAPConnection.call, or SOAPMessage.writeTo. However, if changes are made to a message that was received or to one that has already been sent, the method saveChanges needs to be called explicitly in order to save the changes. The method saveChanges also generates any changes that can be read back (for example, a MessageId in profiles that support a message id). All MIME headers in a message that is created for sending purposes are guaranteed to have valid values only after saveChanges has been called.

In addition, this method marks the point at which the data from all constituent AttachmentPart objects are pulled into the message.

Overrides:
saveChanges in class SOAPMessageImpl
Throws:
javax.xml.soap.SOAPException - if there was a problem saving changes to this message.

saveRequired

public boolean saveRequired()
Indicates whether this SOAPMessage object has had the method saveChanges called on it.

Overrides:
saveRequired in class SOAPMessageImpl
Returns:
true if saveChanges has been called on this message at least once; false otherwise.

getMimeHeaders

public javax.xml.soap.MimeHeaders getMimeHeaders()
Returns all the transport-specific MIME headers for this SOAPMessage object in a transport-independent fashion.

Overrides:
getMimeHeaders in class SOAPMessageImpl
Returns:
a MimeHeaders object containing the MimeHeader objects

removeAllAttachments

public void removeAllAttachments()
Removes all AttachmentPart objects that have been added to this SOAPMessage object.

This method does not touch the SOAP part.

Overrides:
removeAllAttachments in class SOAPMessageImpl

countAttachments

public int countAttachments()
Gets a count of the number of attachments in this message. This count does not include the SOAP part.

Overrides:
countAttachments in class SOAPMessageImpl
Returns:
the number of AttachmentPart objects that are part of this SOAPMessage object

getAttachments

public Iterator getAttachments()
Retrieves all the AttachmentPart objects that are part of this SOAPMessage object.

Overrides:
getAttachments in class SOAPMessageImpl
Returns:
an iterator over all the attachments in this message

getAttachments

public Iterator getAttachments(javax.xml.soap.MimeHeaders headers)
Retrieves all the AttachmentPart objects that have header entries that match the specified headers. Note that a returned attachment could have headers in addition to those specified.

Overrides:
getAttachments in class SOAPMessageImpl
Parameters:
headers - a MimeHeaders object containing the MIME headers for which to search
Returns:
an iterator over all attachments that have a header that matches one of the given headers

addAttachmentPart

public void addAttachmentPart(javax.xml.soap.AttachmentPart attachmentpart)
Adds the given AttachmentPart object to this SOAPMessage object. An AttachmentPart object must be created before it can be added to a message.

Overrides:
addAttachmentPart in class SOAPMessageImpl
Parameters:
attachmentpart - an AttachmentPart object that is to become part of this SOAPMessage object
Throws:
IllegalArgumentException

createAttachmentPart

public javax.xml.soap.AttachmentPart createAttachmentPart()
Creates a new empty AttachmentPart object. Note that the method addAttachmentPart must be called with this new AttachmentPart object as the parameter in order for it to become an attachment to this SOAPMessage object.

Overrides:
createAttachmentPart in class SOAPMessageImpl
Returns:
a new AttachmentPart object that can be populated and added to this SOAPMessage object

dispose

public void dispose()
