java.lang.Object
  org.gedcomx.util.XmlRecordSetIterator

All Implemented Interfaces:

Iterator<Gedcomx>, RecordSetIterator

public class XmlRecordSetIterator
extends Object
implements RecordSetIterator

Class for iterating through the 'record' elements (GedcomX documents) in a RecordSet one at a time from a stream (e.g., a gzipped byte array) without having to inflate all the records at once. This is for a RecordSet serialized to XML. User: Randy Wilson Date: 7/31/2014 Time: 1:58 PM

Constructor Summary

XmlRecordSetIterator(BufferedReader reader)
Constructor for a record iterator that takes a BufferedReader of a RecordSet file and iterates through its record elements.

XmlRecordSetIterator(InputStream inputStream)
Constructor for a record iterator that takes an InputStream of a RecordSet file and iterates through its record elements.

XmlRecordSetIterator(InputStream inputStream, boolean isGzipped)

XmlRecordSetIterator(String filename)
Constructor for a record iterator that takes a filename of a RecordSet file and iterates through its record elements.

Method Summary

void	close() Close the input stream and accompanying reader if they are still open.
Gedcomx	getMetadata() Retrieve the metadata for the RecordSet.
boolean	hasNext() Tell whether the RecordIterator has another GedcomX record to return.
Gedcomx	next() Get the next Gedcomx Record from the RecordSet.
void	remove()

Method Detail

hasNext

public boolean hasNext()

Tell whether the RecordIterator has another GedcomX record to return.

Specified by:

hasNext in interface Iterator<Gedcomx>

Specified by:

hasNext in interface RecordSetIterator

Returns:

true if there is another record to read; false otherwise.

next

public Gedcomx next()

Description copied from interface: RecordSetIterator

Get the next Gedcomx Record from the RecordSet.

Specified by:

next in interface Iterator<Gedcomx>

Specified by:

next in interface RecordSetIterator

Returns:

the next Gedcomx Record from the RecordSet.

getMetadata

public Gedcomx getMetadata()

Description copied from interface: RecordSetIterator

Retrieve the metadata for the RecordSet.

Specified by:

getMetadata in interface RecordSetIterator

Returns:

A Gedcomx document representing the metadata (or collection information) of the RecordSet.

remove

public void remove()

Specified by:

remove in interface Iterator<Gedcomx>

Specified by:

remove in interface RecordSetIterator

close

public void close()

Close the input stream and accompanying reader if they are still open. If an exception occurs trying to close things, it is caught here.

Specified by:
