Constant WRITERNAME="XercesSaxNESTWorkflowWriter"

Constant Field Values

Constructor Detail

NESTWorkflowWriterImpl

public NESTWorkflowWriterImpl()

Method Detail

getDescription

public String getDescription()

A description of the io component. The description should contain the file format and the classes that can be managed.

Specified by:

getDescription in interface IO

Overrides:

getDescription in class NESTSequentialWorkflowWriterImpl

Returns:

a description of the io component

getName

public String getName()

Each io component must have a name that is used in IOFactory.newIO(String). The name must be unique thus it is usefull to use a short description or to the class name ( this.getClass().getName()).

Specified by:

getName in interface IO

Overrides:

getName in class NESTSequentialWorkflowWriterImpl

Returns:

Returns the name of the io component.

isHandlerFor

public boolean isHandlerFor(Class value)

Checks if the io component is capable to perform the operation for objects of this class.

A typical implementation looks like:

 public boolean isHandlerFor(Class value) {
        if (DataObject.class.isAssignableFrom(value))
                return true;
        return false;
 }
 

Specified by:

isHandlerFor in interface IO

Overrides:

isHandlerFor in class NESTSequentialWorkflowWriterImpl

Parameters:

value - The class that has to be checked.

Returns:

Results true if the class can oeprate with the given class.

copy

public IO copy()

overwritten copy-method from Object; use it to copy a complete operator

Specified by:

copy in interface IO

Overrides:

copy in class NESTSequentialWorkflowWriterImpl

Returns:

store

public void store(Object value,
                  XMLSchemaBasedWriter writer)
           throws CakeIOException

To embed xml writers into another one it must be possible to specify the parent XMLSchemaBasedWriter as well as a prefix that should be probably used. If a parent writer is specified, no header will be written.

If the writer does not support XML writing, the writer should throw an UnsupportedOperationException.

 public void store(Object value, String prefix, XMLWriter writer) throws CakeIOException {
        throw new UnsupportedOperationException();
 }
 

Overrides:

store in class NESTSequentialWorkflowWriterImpl

Parameters:

value - a Object object

writer - A parent writer that is used.

Throws:

CakeIOException - if any.

writeNode

protected void writeNode(NESTNodeObject value,
                         XMLSchemaBasedWriter writer)
                  throws XMLStreamException,
                         CakeIOException,
                         IOException,
                         InvalidNativeValueException

Writes the Node-object into the XMLWriter. Writes the Node-object into the XMLWriter. Writes the Node-object into the XMLWriter.

Overrides:

writeNode in class NESTSequentialWorkflowWriterImpl

Parameters:

value - The Node-object to write.

writer - The writer to write the output to.

Throws:

XMLStreamException

CakeIOException

InvalidNativeValueException

IOException
