class StaxSource
extends SAXSource

Implementation of the Source tagging interface for StAX readers. Can be constructed with an XMLEventReader or an XMLStreamReader.

This class is necessary because there is no implementation of Source for StAX Readers in JAXP 1.3. There is a StAXSource in JAXP 1.4 (JDK 1.6), but this class is kept around for backwards compatibility reasons.

Even though StaxSource extends from SAXSource, calling the methods of SAXSource is not supported. In general, the only supported operation on this class is to use the XMLReader obtained via SAXSource.getXMLReader() to parse the input source obtained via SAXSource.getInputSource(). Calling setXMLReader(XMLReader) or setInputSource(InputSource) will result in UnsupportedOperationException #setInputSource(InputSource) will result in UnsupportedOperationExceptions.

构造器详细资料

StaxSource

StaxSource(XMLEventReader eventReader)

Construct a new instance of the StaxSource with the specified XMLEventReader. The supplied event reader must be in XMLStreamConstants.START_DOCUMENT or XMLStreamConstants.START_ELEMENT state.

参数:

eventReader - the XMLEventReader to read from

抛出:

IllegalStateException - if the reader is not at the start of a document or element

StaxSource

StaxSource(XMLStreamReader streamReader)

Construct a new instance of the StaxSource with the specified XMLStreamReader. The supplied stream reader must be in XMLStreamConstants.START_DOCUMENT or XMLStreamConstants.START_ELEMENT state.

参数:

streamReader - the XMLStreamReader to read from

抛出:

IllegalStateException - if the reader is not at the start of a document or element

方法详细资料

getXMLEventReader

@Nullable
XMLEventReader getXMLEventReader()

Return the XMLEventReader used by this StaxSource.

If this StaxSource was created with an XMLStreamReader, the result will be null.

返回:

the StAX event reader used by this source

getXMLStreamReader

@Nullable
XMLStreamReader getXMLStreamReader()

Return the XMLStreamReader used by this StaxSource.

If this StaxSource was created with an XMLEventReader, the result will be null.

返回:

the StAX event reader used by this source

setInputSource

public void setInputSource(InputSource inputSource)

Throws an UnsupportedOperationException.

覆盖:

setInputSource 在类中 SAXSource

抛出:

UnsupportedOperationException - always

setXMLReader

public void setXMLReader(XMLReader reader)

Throws an UnsupportedOperationException.

覆盖:

setXMLReader 在类中 SAXSource

抛出:

UnsupportedOperationException - always
