Attachments

public Attachments()

Use this constructor when instantiating this to store the attachments set programatically through the SwA API.

Method Detail

getLifecycleManager

public LifecycleManager getLifecycleManager()

setLifecycleManager

public void setLifecycleManager(LifecycleManager manager)

getAttachmentSpecType

public String getAttachmentSpecType()

Identify the type of message (MTOM or SOAP with attachments) represented by this object. Note that this method is only meaningful if the instance was created from a stream.

Returns:

One of the MTOMConstants.MTOM_TYPE, MTOMConstants.SWA_TYPE or MTOMConstants.SWA_TYPE_12 constants.

Throws:

OMException - if the message doesn't have one of the supported types (i.e. is neither MTOM nor SOAP with attachments) or if the instance was not created from a stream

getDataHandler

public DataHandler getDataHandler(String contentID)

Get the DataHandler object for the MIME part with a given content ID. The returned instance MAY implement DataHandlerExt in which case the caller can use that API to stream the content of the part. In addition, the DataSource linked to the returned DataHandler MAY be of type SizeAwareDataSource in which case the caller can use that interface to determine the size of the MIME part.

Specified by:

getDataHandler in interface OMAttachmentAccessor

Parameters:

contentID - the raw content ID (without the surrounding angle brackets and cid: prefix) of the MIME part

Returns:

the DataHandler of the MIME part referred by the content ID or null if the MIME part referred by the content ID does not exist

addDataHandler

public void addDataHandler(String contentID,
                           DataHandler dataHandler)

Programatically adding an SOAP with Attachments(SwA) Attachment. These attachments will get serialized only if SOAP with Attachments is enabled.

Parameters:

contentID -

dataHandler -

removeDataHandler

public void removeDataHandler(String blobContentID)

Removes the DataHandler corresponding to the given contenID. If it is not present, then trying to find it calling the getNextPart() till the required part is found.

Parameters:

blobContentID -

getSOAPPartInputStream

public InputStream getSOAPPartInputStream()
                                   throws OMException

Deprecated.

Use getRootPartInputStream() instead.

Throws:

OMException

getSOAPPartContentID

public String getSOAPPartContentID()

Deprecated.

Use getRootPartContentID() instead.

getSOAPPartContentType

public String getSOAPPartContentType()

Deprecated.

Use getRootPartContentType() instead.

getRootPartInputStream

public InputStream getRootPartInputStream()
                                   throws OMException

Get an input stream for the root part of the MIME message. The root part is located as described in the documentation of the getRootPartContentID() method. Note that a new stream is returned each time this method is called, i.e. the method does not consume the root part. Instead it loads the root part into memory so that it can be read several times.

Returns:

the input stream for the root part

Throws:

OMException

getRootPartInputStream

public InputStream getRootPartInputStream(boolean preserve)
                                   throws OMException

Get an input stream for the root part of the MIME message. This method is similar to getRootPartInputStream(), but can be instructed to consume the root part. This allows streaming of the root part. If that feature is used, the root part will not be loaded into memory unless an attempt is made to access another part of the MIME message, in which case the remaining (i.e. unconsumed) content of the root part will be buffered. If the feature is not enabled, then this method behaves in the same way as getRootPartInputStream().

Parameters:

preserve - true if the content of the root part should be fetched into memory so that it can be read several times, false if the root part should be consumed

Returns:

the input stream for the root part

Throws:

OMException

getRootPartContentID

public String getRootPartContentID()

Get the content ID of the root part of the MIME message. This content ID is determined as follows:

• If the content type of the MIME message has a start parameter, then the content ID will be extracted from that parameter.
• Otherwise the content ID of the first MIME part of the MIME message is returned.

Returns:

the content ID of the root part (without the surrounding angle brackets)

getRootPartContentType

public String getRootPartContentType()

Get the content type of the root part of the MIME message. The root part is located as described in the documentation of the getRootPartContentID() method.

Returns:

the content type of the root part

Throws:

OMException - if the content type could not be determined

getIncomingAttachmentStreams

public IncomingAttachmentStreams getIncomingAttachmentStreams()
                                                       throws IllegalStateException

Stream based access

Returns:

The stream container of type IncomingAttachmentStreams

Throws:

IllegalStateException - if application has alreadt started using Part's directly

getAllContentIDs

public String[] getAllContentIDs()

Get the content IDs of all MIME parts in the message. This includes the content ID of the SOAP part as well as the content IDs of the attachments. Note that if this object has been created from a stream, a call to this method will force reading of all MIME parts that have not been fetched from the stream yet.

Returns:

an array with the content IDs in order of appearance in the message

getContentIDSet

public Set<String> getContentIDSet()

Get the content IDs of all MIME parts in the message. This includes the content ID of the SOAP part as well as the content IDs of the attachments. Note that if this object has been created from a stream, a call to this method will force reading of all MIME parts that have not been fetched from the stream yet.

Returns:

the set of content IDs

getMap

public Map<String,DataHandler> getMap()

Get a map of all MIME parts in the message. This includes the SOAP part as well as the attachments. Note that if this object has been created from a stream, a call to this method will force reading of all MIME parts that have not been fetched from the stream yet.

Returns:

A map of all MIME parts in the message, with content IDs as keys and DataHandler objects as values.

getContentIDList

public List<String> getContentIDList()

Get the content IDs of the already loaded MIME parts in the message. This includes the content ID of the SOAP part as well as the content IDs of the attachments. If this object has been created from a stream, only the content IDs of the MIME parts that have already been fetched from the stream are returned. If this is not the desired behavior, getAllContentIDs() or getContentIDSet() should be used instead.

Returns:

List of content IDs in order of appearance in message

getContentLength

public long getContentLength()
                      throws IOException

If the Attachments is backed by an InputStream, then this method returns the length of the message contents (Length of the entire message - Length of the Transport Headers)

Returns:

length of message content or -1 if Attachments is not backed by an InputStream

Throws:

IOException

getIncomingAttachmentsAsSingleStream

public InputStream getIncomingAttachmentsAsSingleStream()
                                                 throws IllegalStateException

Deprecated.

As of Axiom 1.2.13, this method is no longer supported.

Throws:

IllegalStateException

getMultipartBody

public MultipartBody getMultipartBody()
