Java PropertyManager類使用實例

實例1: getXMLStreamReaderImpl

import com.sun.org.apache.xerces.internal.impl.PropertyManager; //導入依賴的package包/類XMLStreamReader getXMLStreamReaderImpl(XMLInputSource inputSource) throws javax.xml.stream.XMLStreamException{    //1. if the temp reader is null -- create the instance and return    if(fTempReader == null){        fPropertyChanged = false;        return fTempReader = new XMLStreamReaderImpl(inputSource,                new PropertyManager(fPropertyManager));    }    //if factory is configured to reuse the instance & this instance can be reused    //& the setProperty() hasn't been called    if(fReuseInstance && fTempReader.canReuse() && !fPropertyChanged){        if(DEBUG)System.out.println("Reusing the instance");        //we can make setInputSource() call reset() and this way there wont be two function calls        fTempReader.reset();        fTempReader.setInputSource(inputSource);        fPropertyChanged = false;        return fTempReader;    }else{        fPropertyChanged = false;        //just return the new instance.. note that we are not setting  fTempReader to the newly created instance        return fTempReader = new XMLStreamReaderImpl(inputSource,                new PropertyManager(fPropertyManager));    }} 

實例2: createXMLStreamWriter

import com.sun.org.apache.xerces.internal.impl.PropertyManager; //導入依賴的package包/類javax.xml.stream.XMLStreamWriter createXMLStreamWriter(javax.xml.transform.stream.StreamResult sr, String encoding) throws javax.xml.stream.XMLStreamException {    //if factory is configured to reuse the instance & this instance can be reused    //& the setProperty() hasn't been called    try{        if(fReuseInstance && fStreamWriter != null && fStreamWriter.canReuse() && !fPropertyChanged){            fStreamWriter.reset();            fStreamWriter.setOutput(sr, encoding);            if(DEBUG)System.out.println("reusing instance, object id : " + fStreamWriter);            return fStreamWriter;        }        return fStreamWriter = new XMLStreamWriterImpl(sr, encoding, new PropertyManager(fPropertyManager));    }catch(java.io.IOException io){        throw new XMLStreamException(io);    }} 

實例3: XMLStreamWriterImpl

import com.sun.org.apache.xerces.internal.impl.PropertyManager; //導入依賴的package包/類/** * Creates a new instance of XMLStreamWriterImpl. Uses platform's default * encoding. * * @param outputStream Underlying stream to write the bytes to * @param props        Properties used by this writer */public XMLStreamWriterImpl(OutputStream outputStream, PropertyManager props)    throws IOException {    // cannot call this(outputStream, null, props); for constructor,    // OutputStreamWriter charsetName cannot be null    // use default encoding    this(new OutputStreamWriter(outputStream), props);}
