Field Detail

identifier

public java.lang.String identifier

The item's ADL identifier, e.g., "adl_catalog:1001652".

buckets

public java.util.Hashtable buckets

The item's bucket mappings. The hashtable maps bucket names (e.g., "adl:titles") to arrays of Values.

Constructor Detail

BucketReport

public BucketReport(java.io.Reader reader)
             throws XmlException

Creates a BucketReport.

Parameters:

reader - The source of the bucket report.

Throws:

XmlException - If any error is encountered.

Method Detail

startElement

public void startElement(int elementCode,
                         java.lang.String[] attributes)
                  throws XmlException

For use by ValidatingXmlParser only.

Specified by:

startElement in interface XmlHandler

Parameters:

elementCode - The element's code.

attributes - Element attribute values, indexed by attribute code. All of the element's declared attributes are represented in the array; attributes for which a value is specified in the document or for which there is a DTD-specified default have non-null values. The handler should reference the array for the duration of the call only, as it is reused by the parser. Also, the array may be longer than necessary.

Throws:

XmlException - If any error occurs.

endElement

public void endElement(int elementCode)
                throws XmlException

For use by ValidatingXmlParser only.

Specified by:

endElement in interface XmlHandler

Parameters:

elementCode - The element's code.

Throws:

XmlException - If any error occurs.

characters

public void characters(char[] string,
                       int start,
                       int length)

For use by ValidatingXmlParser only.

Specified by:

characters in interface XmlHandler

Parameters:

string - The textual content.

start - The index in string at which the textual content starts.

length - The length of the content.

main

public static void main(java.lang.String[] args)
                 throws java.io.IOException,
                        XmlException,
                        java.lang.IllegalAccessException
