All Implemented Interfaces:

XMLStreamConstants, XMLStreamReader

public class JsonXMLStreamReader
extends AbstractXMLStreamReader<de.odysseus.staxon.json.JsonXMLStreamReader.ScopeInfo>

JSON XML stream reader.

Limitations

• Mixed content (e.g. <alice>bob<edgar/></alice>) is not supported.

The reader may produce processing instructions <?xml-multiple element-name?> to indicate array starts ('[').

JsonXMLStreamReader

public JsonXMLStreamReader(JsonStreamSource source,
                           boolean multiplePI,
                           char namespaceSeparator)
                    throws XMLStreamException

Create reader instance.

Parameters:

source - stream source

multiplePI - whether to produce <xml-multiple?> PIs to signal array start

namespaceSeparator - namespace prefix separator

Throws:

XMLStreamException

Method Detail

consume

protected boolean consume()
                   throws XMLStreamException,
                          IOException

Description copied from class: AbstractXMLStreamReader

Main method to be implemented by subclasses. This method is called by the reader when the event queue runs dry. Consume some events and delegate to the various readXXX() methods. When encountering an element start event, all attributes and namespace delarations must be consumed too, otherwise these won't be available during start element.

Specified by:

consume in class AbstractXMLStreamReader<de.odysseus.staxon.json.JsonXMLStreamReader.ScopeInfo>

Returns:

true if there's more to read

Throws:

XMLStreamException

IOException

hasNumber

public boolean hasNumber()

Returns:

true iff the current event data is a number primitive

getNumber

public Number getNumber()

Returns:

number primitive

Throws:

ClassCastException

hasBoolean

public boolean hasBoolean()

Returns:

true iff the current event data is a boolean primitive

getBoolean

public Boolean getBoolean()

Returns:

boolean primitive

Throws:

ClassCastException

close

public void close()
           throws XMLStreamException

Specified by:

close in interface XMLStreamReader

Overrides:

close in class AbstractXMLStreamReader<de.odysseus.staxon.json.JsonXMLStreamReader.ScopeInfo>

Throws:

XMLStreamException
