Examples with ProcessDiagramLayoutFactory org.camunda.bpm.engine.impl.bpmn.diagram.ProcessDiagramLayoutFactory used on opensource projects

Example 1 with ProcessDiagramLayoutFactory

use of org.camunda.bpm.engine.impl.bpmn.diagram.ProcessDiagramLayoutFactory in project camunda-bpm-platform by camunda.

the class GetDeploymentProcessDiagramLayoutCmd method execute.

public DiagramLayout execute(final CommandContext commandContext) {
    ProcessDefinitionEntity processDefinition = Context.getProcessEngineConfiguration().getDeploymentCache().findDeployedProcessDefinitionById(processDefinitionId);
    for (CommandChecker checker : commandContext.getProcessEngineConfiguration().getCommandCheckers()) {
        checker.checkReadProcessDefinition(processDefinition);
    }
    InputStream processModelStream = commandContext.runWithoutAuthorization(new Callable<InputStream>() {

        public InputStream call() throws Exception {
            return new GetDeploymentProcessModelCmd(processDefinitionId).execute(commandContext);
        }
    });
    InputStream processDiagramStream = commandContext.runWithoutAuthorization(new Callable<InputStream>() {

        public InputStream call() throws Exception {
            return new GetDeploymentProcessDiagramCmd(processDefinitionId).execute(commandContext);
        }
    });
    return new ProcessDiagramLayoutFactory().getProcessDiagramLayout(processModelStream, processDiagramStream);
}
