public class XMLBulkLoad

extends Activity

This activity bulk loads a set of documents into an XML collection exposed by an XMLDB data service resource. The documents can either be included in-line in the request or can be read from another activity's output. If a collection is named but does not exist then it can be created if this option is set (see setCollectionName).

The activity has one (optional) input - XML data from another activity - and one output - the number of resources bulk loaded. The format of the output is OGSA-DAI specific XML. For example:

<resultCount> 2 </resultCount>

XMLBulkLoad

public XMLBulkLoad()

Constructs a request to bulk load resources into a collection. The documents must be specified using setInput or setInputData By default the documents will be bulk loaded into the base collection.

XMLBulkLoad

public XMLBulkLoad(ActivityOutput input)

Constructs a request to bulk load data into a collection. By default the documents will be bulk loaded into the base collection.

Parameters:

input - Output from another activity.

Throws:

java.lang.IllegalArgumentException - If input is null.

setInput

public final void setInput(ActivityOutput input)

Sets the input of this activity to be the output from another activity that will provide the XML content of the new resource.

Parameters:

input - Output from another activity.

Throws:

java.lang.IllegalArgumentException - If input is null.

setInputData

public void setInputData(org.xmldb.api.base.ResourceSet resources)
                  throws XMLDBResourceException

Sets the input data for the bulk load to be the resources held within a org.xmldb.api.base.ResourceSet.

Parameters:

resources - ResourceSet

Throws:

XMLDBResourceException - If the resourceSet data cannot be written to a string.

setInputData

public void setInputData(java.lang.String content)
                  throws XMLDBResourceException

Sets the input data for the bulk load. The data must be a valid XML document fragment in the following format (however, no check is made for conformance to this format only for valid XML).

• Exactly resourceSet element containing:
• Zero or more resource elements.

For example:

 <resourceSet>
   <resource>
     <entry id="1">
       <name>Ally Antonioletti</name>
       <address>826 Hume Crescent, Southampton</address>
       <phone>01670061244</phone>

       <address>224 Palansuriya Lane, Winchester</address>
       <phone>06686142062</phone>
     </entry>
   </resource>
 </resourceSet>
 

Parameters:

content - A string containing the data for bulk load.

Throws:

XMLDBResourceException - If content is not null and cannot be parsed as XML.

setInputData

public void setInputData(org.w3c.dom.Document document)

Sets the input data for the bulk load. The data must be a valid XML document fragment in the same format as that of setInputData(java.lang.String) (however, no check is made for conformance to this format only for valid XML).

Parameters:

document - An XML fragment containing the data for bulk load.

setCollectionName

public void setCollectionName(java.lang.String collectionName)

Set the collection name. The resources will be loaded into this collection. If this is set to null then the resource will loaded in the base collection. If the collection does not exist then it will not be created and the activity will raise an error.

Parameters:

collectionName - The name of the collection or null.

setCollectionName

public void setCollectionName(java.lang.String collectionName,
                              boolean createIfNotExists)

Set the collection name. The resources will be loaded into this collection. If this is set to null then the resource will loaded in the base collection.

Parameters:

collectionName - The name of the collection or null.

createIfNotExists - If collectionName is not null and does not exist then should it be created? The collection can only be created if all its parent collections exist. For example: littleblackbook/address/newCollection - the new collection newCollection can only be created if the parent collections littleblackbook and address exist.
