Method Detail

readModelFromFile

public static BpmnModelInstance readModelFromFile(File file)

Allows reading a BpmnModelInstance from a File.

Parameters:

file - the File to read the BpmnModelInstance from

Returns:

the model read

Throws:

BpmnModelException - if the model cannot be read

readModelFromStream

public static BpmnModelInstance readModelFromStream(InputStream stream)

Allows reading a BpmnModelInstance from an InputStream

Parameters:

stream - the InputStream to read the BpmnModelInstance from

Returns:

the model read

Throws:

writeModelToFile

public static void writeModelToFile(File file,
                                    BpmnModelInstance modelInstance)

Allows writing a BpmnModelInstance to a File. It will be validated before writing.

Parameters:

file - the File to write the BpmnModelInstance to

modelInstance - the BpmnModelInstance to write

Throws:

BpmnModelException - if the model cannot be written

ModelValidationException - if the model is not valid

writeModelToStream
