index - the index of the resource to retrieve.

Returns:

the Resource instance.

XMLDBException

getSize

public long getSize()
             throws XMLDBException

Returns the number of resources contained in the set.

Specified by:

getSize in interface ResourceSet

Returns:

the number of Resource instances in the set.

Throws:

XMLDBException

addResource

public void addResource(Resource res)
                 throws XMLDBException

Adds a Resource instance to the set.

Specified by:

addResource in interface ResourceSet

Parameters:

res - The Resource to add to the set.

XMLDBException

clear

public void clear()
           throws XMLDBException

Removes all Resource instances from the set.

public void removeResource(long index)
                    throws XMLDBException

Removes the Resource located at index from the set.

Specified by:

removeResource in interface ResourceSet

Parameters:

index - The index of the Resource instance to remove.

Throws:

XMLDBException

getMembersAsResource

public Resource getMembersAsResource()
                              throws XMLDBException

Returns a Resource containing an XML representation of all resources stored in the set.

TODO: Specify the schema used for this

Specified by:

getMembersAsResource in interface ResourceSet

Returns:

A Resource instance containing an XML representation of all set members.

Throws:

XMLDBException - with expected error codes.
ErrorCodes.VENDOR_ERROR for any vendor specific errors that occur.

buildMembersAsResourceDocument

public org.w3c.dom.Document buildMembersAsResourceDocument()
                                                    throws XMLDBException

Turns the List into the proper XML format to implement getMembersAsResource. This is a helper method to make implementing getMembersAsResource easier. The result is a DOM document that should be converted into a proper XMLResource implementation by the implementing driver.

Throws:

XMLDBException
