Method Detail

getOMElement

public org.apache.axiom.om.OMElement getOMElement()
                                           throws XMLStreamException,
                                                  WebServiceException

Description copied from interface: Block

Get the OMElement represented by this Block. This call always consumes the block because you are taking control of the underlying OM

Specified by:

getOMElement in interface Block<DataSource,Void>

Overrides:

getOMElement in class BlockImpl<DataSource,Void>

Returns:

Throws:

XMLStreamException

WebServiceException

_getBOFromOM

protected DataSource _getBOFromOM(org.apache.axiom.om.OMElement omElement,
                                  Void busContext)
                           throws XMLStreamException,
                                  WebServiceException

Description copied from class: BlockImpl

Default method for getting business object from OM. Derived classes may override this method to get the business object from a data source.

Specified by:

_getBOFromOM in class BlockImpl<DataSource,Void>

Returns:

Business Object

Throws:

XMLStreamException

WebServiceException

_getReaderFromBO

protected XMLStreamReader _getReaderFromBO(DataSource busObj,
                                           Void busContext)
                                    throws XMLStreamException,
                                           WebServiceException

Description copied from class: BlockImpl

Get an XMLStreamReader for the BusinessObject The derived Block must implement this method

Specified by:

_getReaderFromBO in class BlockImpl<DataSource,Void>

Returns:

Throws:

XMLStreamException

WebServiceException

_outputFromBO

protected void _outputFromBO(DataSource busObject,
                             Void busContext,
                             XMLStreamWriter writer)
                      throws XMLStreamException,
                             WebServiceException

Description copied from class: BlockImpl

Output BusinessObject contents to a Writer. Derived classes must provide this implementation

Specified by:

_outputFromBO in class BlockImpl<DataSource,Void>

Throws:

XMLStreamException

WebServiceException

_getBOFromBO

protected DataSource _getBOFromBO(DataSource busObject,
                                  Void busContext,
                                  boolean consume)

Description copied from class: BlockImpl

The default implementation is to return the business object. A derived block may want to override this class if the business object is consumed when read (thus the dervived block may want to make a buffered copy) (An example use case for overriding this method is the businessObject is an InputSource)

Overrides:

_getBOFromBO in class BlockImpl<DataSource,Void>

Returns:

isElementData

public boolean isElementData()

Specified by:

isElementData in interface Block<DataSource,Void>

Returns:

true if data is always an element; false if possibly mixed content or multiple elements

close

public void close()

Specified by:

close in interface org.apache.axiom.om.OMDataSourceExt

Overrides:

close in class org.apache.axiom.om.ds.AbstractOMDataSource

getObject

public Object getObject()

Specified by:

getObject in interface org.apache.axiom.om.OMDataSourceExt

Overrides:

getObject in class org.apache.axiom.om.ds.AbstractOMDataSource

isDestructiveRead

public boolean isDestructiveRead()

Specified by:

isDestructiveRead in interface org.apache.axiom.om.OMDataSourceExt

isDestructiveWrite

public boolean isDestructiveWrite()

Specified by:

isDestructiveWrite in interface org.apache.axiom.om.OMDataSourceExt
