Method Detail

replaceDeveloperFriendlyIds

public String replaceDeveloperFriendlyIds(String sourceModel,
                                          String processEnginePoolId)

Replaces the bpmn element IDs in a process model with developer friendly IDs.

Parameters:

sourceModel - a bpmn20 process model in XML representation

processEnginePoolId - allows to provide a custom ID that is used for the first element with 'isExecutable="true"' that is found by the transformer

Returns:

the process model such that the element ids are replaced with developer-friendly IDs

replaceDeveloperFriendlyIds

public String replaceDeveloperFriendlyIds(String sourceModel)

Replaces the bpmn element IDs in a process model with developer friendly IDs.

Parameters:

sourceModel - a bpmn20 process model in XML representation

Returns:

the process model such that the element ids are replaced with developer-friendly IDs

extractExecutablePool

public String extractExecutablePool(String sourceModel)

Extract executable pool based on string data

Parameters:

sourceModel -

Returns:

extractExecutablePool(java.io.InputStream)

extractExecutablePool

public InputStream extractExecutablePool(InputStream sourceModel)

Takes a bpmn process model in XML representation as input. Removes all pools except for a single executable pool (property 'isExecutable="true"). NOTE: assumes that the process model contains a single executable pool.

Parameters:

sourceModel - a bpmn20 process model in XML representation

Returns:

the process model containing the extracted pool

importChangesFromExecutableBpmnModel

public String importChangesFromExecutableBpmnModel(String sourceModel,
                                                   String targetModel)

Import the changes from a source bpmn process model to a target bpmn process model.
