Method Detail

load

public static Pair<String,Bean<Configuration>> load(InputStream stream,
                                                    String encoding)
                                             throws IOException,
                                                    DocUtil.XMLException

Loads a diagram from the text transmitted through the given stream. If the text contains a line that starts with <?xml, it is interpreted as an XML file, containing the diagram source as a CDATA section along with a configuration. Otherwise the whole of the text is interpreted as a diagram source, and a default configuration is used.

Parameters:

stream - the stream from where the diagram specification is read

encoding - the encoding of the diagram specification

Returns:

a pair of the diagram source and the configuration to be used for generating the diagram

Throws:

IOException

DocUtil.XMLException

saveDiagram

public static void saveDiagram(String source,
                               Bean<Configuration> configuration,
                               OutputStream stream,
                               String encoding)
                        throws IOException,
                               DocUtil.XMLException

Saves a diagram specification (and a configuration), using a stream.

Parameters:

source - the source text of the diagram

configuration - a configuration of the diagram, or null if it is to be saved without a configuration (as plain text)

stream - the stream to use for saving the diagram source and configuration

encoding - the encoding to be used

Throws:

IOException

DocUtil.XMLException
