DefaultConfigurationSerializer

public DefaultConfigurationSerializer()

Method Detail

setIndent

public void setIndent(boolean indent)

Sets the Serializer's use of indentation. This will cause linefeeds to be added after each element, but it does not add any indentation via spaces.

Parameters:

indent - a boolean value

createContentHandler

protected org.xml.sax.ContentHandler createContentHandler(javax.xml.transform.Result result)

Create a ContentHandler for an OutputStream

Parameters:

result - the result

Returns:

contenthandler that goes to specified OutputStream

getTransformerFactory

protected javax.xml.transform.sax.SAXTransformerFactory getTransformerFactory()

Get the SAXTransformerFactory so we can get a serializer without being tied to one vendor.

Returns:

a SAXTransformerFactory value

serialize

public void serialize(org.xml.sax.ContentHandler handler,
                      Configuration source)
               throws org.xml.sax.SAXException,
                      ConfigurationException

Serialize the configuration to a ContentHandler

Parameters:

handler - a ContentHandler to serialize to

source - a Configuration value

Throws:

org.xml.sax.SAXException - if an error occurs

ConfigurationException - if an error occurs

serializeElement

protected void serializeElement(org.xml.sax.ContentHandler handler,
                                org.xml.sax.helpers.NamespaceSupport namespaceSupport,
                                Configuration element)
                         throws org.xml.sax.SAXException,
                                ConfigurationException

Serialize each Configuration element. This method is called recursively.

Parameters:

handler - a ContentHandler to use

namespaceSupport - a NamespaceSupport to use

element - a Configuration value

Throws:

org.xml.sax.SAXException - if an error occurs

ConfigurationException - if an error occurs

serializeToFile

public void serializeToFile(java.lang.String filename,
                            Configuration source)
                     throws org.xml.sax.SAXException,
                            java.io.IOException,
                            ConfigurationException

Serialize the configuration object to a file using a filename.

Parameters:

filename - a String value

source - a Configuration value

Throws:

org.xml.sax.SAXException - if an error occurs

java.io.IOException - if an error occurs

ConfigurationException - if an error occurs

serializeToFile

                            java.io.IOException,
                            ConfigurationException

Serialize the configuration object to a file using a File object.

Parameters:
