Read a Task's Timephased Data

In Microsoft Project, time-phased data is displayed on the right side of the Task Usage and Resource Usage views. Users can write this data manually and with Aspose.Tasks for Java, you can write it programmatically, or get it from a project into your application.

Working with Timephased Data

Aspose.Tasks for Java supports reading a task’s time-phased data from Microsoft Project (MPP) files. The time-phased data is retrieved using the Task object’s TimeScaleData method.

• To retrieve the task work’s time-phased data, the TimeScaleData method takes the project’s start and finish dates as input parameters.
• To retrieve the task cost’s time-phased data, it takes an additional input parameter that specifies the type of time phase data as TaskCost.

The following piece of code shows how to read a task’s time-phased data.

// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(TaskTimephasedData.class);

Project project = new Project(dataDir + "New project 2010.mpp");

java.util.Calendar cal = java.util.Calendar.getInstance();
cal.set(2013, 7, 17, 8, 0, 0);
project.set(Prj.START_DATE, cal.getTime());
project.set(Prj.NEW_TASKS_ARE_MANUAL, new NullableBool(false));

Task task = project.getRootTask().getChildren().add("Task");
Resource rsc = project.getResources().add("Rsc");
rsc.set(Rsc.STANDARD_RATE, BigDecimal.valueOf(10));
rsc.set(Rsc.OVERTIME_RATE, BigDecimal.valueOf(15));
// 6 days duration
task.set(Tsk.DURATION, project.getDuration(6));

ResourceAssignment assn = project.getResourceAssignments().add(task, rsc);
Date d = new Date(0);
assn.set(Asn.STOP, new Date(0));
assn.set(Asn.RESUME, new Date(0));

// backloaded contour increases task duration from 6 to 10 days
assn.set(Asn.WORK_CONTOUR, WorkContourType.BackLoaded);

project.setBaseline(BaselineType.Baseline);

task.set(Tsk.PERCENT_COMPLETE, 50);

List<TimephasedData> td = assn.getTimephasedData(assn.get(Asn.START), assn.get(Asn.FINISH),
        TimephasedDataType.AssignmentRemainingWork).toList();

System.out.println(td.size());
System.out.println(td.get(0).getValue());
System.out.println(td.get(0).getValue());
System.out.println(td.get(0).getValue());
System.out.println(td.get(0).getValue());
System.out.println(td.get(0).getValue());
System.out.println(td.get(0).getValue());
System.out.println(td.get(0).getValue());
