Class Message

    java.lang.Object
      javax.xml.soap.SOAPMessage
          org.apache.axis.Message

All Implemented Interfaces:
  java.io.Serializable

public class Message
extends SOAPMessage
implements java.io.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?).

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).

  Returns:
    the `Attachments` if attachments are supported, null otherwise

### getContentType

    public java.lang.String getContentType(SOAPConstants sc)
                                    throws AxisFault

  Specified by:
    `writeTo` in class `SOAPMessage`
  Parameters:
    `os` - the `OutputStream` object to which this `SOAPMessage` object will be written
  Throws:
    `SOAPException` - if there was a problem in externalizing this SOAP message
    `java.io.IOException` - if an I/O error occurs

### getSOAPBody

    public SOAPBody getSOAPBody()
                         throws SOAPException

  Description copied from class: `SOAPMessage`
  Gets the SOAP Body contained in this `SOAPMessage` object.

  Overrides:
    `getSOAPBody` in class `SOAPMessage`
  Returns:
    the `SOAPBody` object contained by this `SOAPMessage` object
  Throws:
    `SOAPException` - if the SOAP Body does not exist or cannot be retrieved

### getSOAPHeader

    public SOAPHeader getSOAPHeader()
                             throws SOAPException

  Description copied from class: `SOAPMessage`
  Gets the SOAP Header contained in this `SOAPMessage` object.

  Overrides:
    `getSOAPHeader` in class `SOAPMessage`
  Returns:
    the `SOAPHeader` object contained by this `SOAPMessage` object
  Throws:
    `SOAPException` - if the SOAP Header does not exist or cannot be retrieved

### setProperty

    public void setProperty(java.lang.String property,
                            java.lang.Object value)
                     throws SOAPException

  Description copied from class: `SOAPMessage`
  Associates the specified value with the specified property. If there was already a value associated with this property, the old value is replaced.

  The valid property names include `WRITE_XML_DECLARATION` and `CHARACTER_SET_ENCODING`. All of these standard SAAJ properties are prefixed by "javax.xml.soap". Vendors may also add implementation specific properties. These properties must be prefixed with package names that are unique to the vendor.

  Setting the property `WRITE_XML_DECLARATION` to `"true"` will cause an XML Declaration to be written out at the start of the SOAP message. The default value of "false" suppresses this declaration.

  The property `CHARACTER_SET_ENCODING` defaults to the value `"utf-8"` which causes the SOAP message to be encoded using UTF-8. Setting `CHARACTER_SET_ENCODING` to `"utf-16"` causes the SOAP message to be encoded using UTF-16.

  Some implementations may allow encodings in addition to UTF-8 and UTF-16. Refer to your vendor's documentation for details.

  Overrides:
    `setProperty` in class `SOAPMessage`
  Parameters:
    `property` - the property with which the specified value is to be associated
    `value` - the value to be associated with the specified property
  Throws:
    `SOAPException` - if the property name is not recognized

### getProperty

    public java.lang.Object getProperty(java.lang.String property)
                                 throws SOAPException

  Description copied from class: `SOAPMessage`
  Retrieves value of the specified property.

  Overrides:
    `getProperty` in class `SOAPMessage`
  Parameters:
    `property` - the name of the property to retrieve
  Returns:
    the value of the property or `null` if no such property exists
  Throws:
    `SOAPException` - if the property name is not recognized

### getContentDescription

    public java.lang.String getContentDescription()

  Retrieves a description of this `SOAPMessage` object's content.

  Specified by:
    `getContentDescription` in class `SOAPMessage`
  Returns:
    a `String` describing the content of this message or `null` if no description has been set
  See Also:
    `setContentDescription(java.lang.String)`

### setContentDescription

    public void setContentDescription(java.lang.String description)

  Sets the description of this `SOAPMessage` object's content with the given description.

  Specified by:
    `setContentDescription` in class `SOAPMessage`
  Parameters:
    `description` - a `String` describing the content of this message
  See Also:
    `getContentDescription()`

### saveChanges

    public void saveChanges()
                     throws 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.

  Specified by:
    `saveChanges` in class `SOAPMessage`
  Throws:
    `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.

  Specified by:
    `saveRequired` in class `SOAPMessage`
  Returns:
    `true` if `saveChanges` has been called on this message at least once; `false` otherwise.

### getMimeHeaders

    public MimeHeaders getMimeHeaders()

  Returns all the transport-specific MIME headers for this `SOAPMessage` object in a transport-independent fashion.

  Specified by:
    `getMimeHeaders` in class `SOAPMessage`
  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.

  Specified by:
    `removeAllAttachments` in class `SOAPMessage`

### countAttachments

    public int countAttachments()

  Gets a count of the number of attachments in this message. This count does not include the SOAP part.

  Specified by:
    `countAttachments` in class `SOAPMessage`
  Returns:
    the number of `AttachmentPart` objects that are part of this `SOAPMessage` object

### getAttachments

    public java.util.Iterator getAttachments()

  Retrieves all the `AttachmentPart` objects that are part of this `SOAPMessage` object.

  Specified by:
    `getAttachments` in class `SOAPMessage`
  Returns:
    an iterator over all the attachments in this message

### getAttachments

    public java.util.Iterator getAttachments(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.

  Specified by:
    `getAttachments` in class `SOAPMessage`
  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(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.

  Specified by:
    `addAttachmentPart` in class `SOAPMessage`
  Parameters:
    `attachmentpart` - an `AttachmentPart` object that is to become part of this `SOAPMessage` object
  Throws:
    `java.lang.IllegalArgumentException`

### createAttachmentPart

    public 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.

  Specified by:
    `createAttachmentPart` in class `SOAPMessage`
  Returns:
    a new `AttachmentPart` object that can be populated and added to this `SOAPMessage` object
