org.apache.axis2.jaxws.message.Block

All known Subclasses:   org.apache.axis2.jaxws.message.impl.BlockImpl,
Block
public interface Block extends OMDataSource(Code)
Block A Block represents an xml element and associated sub-tree. The name of the element must be defined by a root element in a schema. All prefixes within the subtree must correspond to namespace declarations defined within the tree. Many specifications refer to this as a "embedded document" or "xml block". I chose the term, block, for simplicity.

The block can be exposed as: * BusinessObject * StAX object

Note that the whole Message can also be thought of as a Block. Thus a Message can be createFrom a Block and written as a Block.

In addition, each of the accessors has a consume parameter. If consume is true, the Block is no longer valid after the message is called. (i.e. the implementation does not need to cache the information)





Method Summary
public  BlockFactorygetBlockFactory()
    
public  ObjectgetBusinessContext()
     GetBusinesContext Some business objects have an associated context object (i.e.
public  ObjectgetBusinessObject(boolean consume)
     Get a reference to the Business Object represented by this Block
Parameters:
  consume - true if this is the last request on the block.
public  OMElementgetOMElement()
     Get the OMElement represented by this Block.
public  MessagegetParent()
    
public  QNamegetQName()
     Get the QName (namespace, localpart) of the Block.
public  XMLStreamReadergetXMLStreamReader(boolean consume)
     Get the XMLStreamReader represented by this Block
Parameters:
  consume - true if this is the last request on the block.
public  booleanisConsumed()
     isConsumed Return true if the block is consumed.
public  booleanisElementData()
    
public  booleanisQNameAvailable()
    
public  voidoutputTo(XMLStreamWriter writer, boolean consume)
    
public  voidsetParent(Message parent)
    
public  StringtraceString(String indent)
     Get a traceString...the trace string dumps the contents of the Block without forcing an underlying ill-performant transformation of the message.



Method Detail
getBlockFactory
public BlockFactory getBlockFactory()(Code)
Get BlockFactory BlockFactory that created the Block



getBusinessContext
public Object getBusinessContext()(Code)
GetBusinesContext Some business objects have an associated context object (i.e. JAXBContext) Context Object or null



getBusinessObject
public Object getBusinessObject(boolean consume) throws XMLStreamException, WebServiceException(Code)
Get a reference to the Business Object represented by this Block
Parameters:
  consume - true if this is the last request on the block. Object (JAXB, String etc.)
throws:
  XMLStreamException -
throws:
  WebServiceException -



getOMElement
public OMElement getOMElement() throws XMLStreamException, WebServiceException(Code)
Get the OMElement represented by this Block. This call always consumes the block because you are taking control of the underlying OM
throws:
  XMLStreamException -
throws:
  WebServiceException -



getParent
public Message getParent()(Code)
Get the Message associated with this block Message



getQName
public QName getQName() throws WebServiceException(Code)
Get the QName (namespace, localpart) of the Block. Do not depend on prefix being set correctly. Asking for the QName can cause a performant hit. QName of the block
See Also:   isQNameAvailable



getXMLStreamReader
public XMLStreamReader getXMLStreamReader(boolean consume) throws XMLStreamException, WebServiceException(Code)
Get the XMLStreamReader represented by this Block
Parameters:
  consume - true if this is the last request on the block. XMLStreamReader
throws:
  XMLStreamException -



isConsumed
public boolean isConsumed()(Code)
isConsumed Return true if the block is consumed. Once consumed, the information in the block is no longer available. true if the block is consumed (a method was called with consume=true)



isElementData
public boolean isElementData()(Code)
true if data is always an element; false if possibly mixed content or multipleelements



isQNameAvailable
public boolean isQNameAvailable()(Code)
If QName is available without doing an expensive parse of the business object, thenreturn true Otherwise return false Note: This method should be used in situations whereit would be nice to know the qname (like logging or a special check) but we don't wantto cause an ill-performant parse.



outputTo
public void outputTo(XMLStreamWriter writer, boolean consume) throws XMLStreamException, WebServiceException(Code)
Write out the Block
Parameters:
  writer - XMLStreamWriter
Parameters:
  consume - true if this is the last request on the block.
throws:
  XMLStreamException -



setParent
public void setParent(Message parent)(Code)
Set the Message associated with this block (This method is intended to be called by the Message Implementation only)
Parameters:
  parent -



traceString
public String traceString(String indent)(Code)
Get a traceString...the trace string dumps the contents of the Block without forcing an underlying ill-performant transformation of the message. String containing trace information
