Read Group Definition Data in Aspose.Tasks

Introduction

Aspose.Tasks for Java is a powerful library that allows developers to manipulate Microsoft Project files with ease. In this tutorial, we’ll walk through the process of reading group definition data from a project file step by step using Aspose.Tasks for Java.

Prerequisites

Before we begin, ensure you have the following prerequisites:

  1. Java Development Kit (JDK): Make sure you have JDK installed on your system.
  2. Aspose.Tasks for Java Library: Download and install the Aspose.Tasks for Java library from here.
  3. Integrated Development Environment (IDE): Choose your preferred IDE such as IntelliJ IDEA or Eclipse.

Import Packages

First, let’s import the necessary packages to begin working with Aspose.Tasks for Java.

import com.aspose.tasks.*;

Step 1: Set Up Your Data Directory

String dataDir = "Your Data Directory";

Replace "Your Data Directory" with the path to the directory containing your project file.

Step 2: Load the Project File

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

Load your project file using the Project class constructor, passing the path to your project file.

Step 3: Retrieve Task Groups Count

System.out.println("Task Groups Count: " + project.getTaskGroups().size());

Retrieve the count of task groups in the project using the getTaskGroups() method.

Step 4: Retrieve Task Group Information

Group taskGroup = project.getTaskGroups().toList().get(1);
System.out.println("Percent Complete:" + taskGroup.getName());
System.out.println("Group Criteria count: " + taskGroup.getGroupCriteria().size());

Retrieve information about a specific task group, such as its name and the count of group criteria.

Step 5: Retrieve Group Criterion Information

GroupCriterion criterion = taskGroup.getGroupCriteria().toList().get(0);
System.out.println("Criterion Field: " + criterion.getField());
System.out.println("Criterion GroupOn: " + criterion.getGroupOn());
System.out.println("Criterion Cell Color: " + criterion.getCellColor());
System.out.println("Criterion Pattern: " + criterion.getPattern());

Retrieve information about the group criteria, such as the field, group on, cell color, and pattern.

Step 6: Check Parent Group

if (taskGroup == criterion.getParentGroup())
    System.out.println("Parent Group is equval to task Group.");

Check if the parent group is equal to the task group.

Step 7: Retrieve Criterion’s Font Information

System.out.println("Font Family Name: " + criterion.getFont().getFontFamily());
System.out.println("Font Size: " + criterion.getFont().getSize());
System.out.println("Font Style: " + criterion.getFont().getStyle());
System.out.println("Ascending/Descending: " + criterion.getAscending());

Retrieve font information for the criterion, such as font family, size, style, and sorting order.

Conclusion

In this tutorial, we’ve learned how to read group definition data from a Microsoft Project file using Aspose.Tasks for Java. By following these steps, you can effectively extract and utilize task group information in your Java applications.
