Retrieve MS Project Outline Codes in Aspose.Tasks

Introduction

In this tutorial, we’ll learn how to retrieve Microsoft Project outline codes using Aspose.Tasks for Java. Outline codes in MS Project provide a structured way to categorize and organize project tasks, resources, and assignments. Aspose.Tasks is a powerful Java library that allows developers to manipulate and manage Microsoft Project files programmatically.

Prerequisites

Before we begin, ensure you have the following prerequisites set up:

1. Java Development Environment

Make sure you have Java Development Kit (JDK) installed on your system. You can download and install JDK from the Oracle website.

2. Aspose.Tasks Library

Download and include the Aspose.Tasks library in your Java project. You can download the library from the Aspose.Tasks for Java Download Page.

Import Packages

First, import the necessary packages from Aspose.Tasks in your Java code:

import com.aspose.tasks.OutlineCodeDefinition;
import com.aspose.tasks.OutlineMask;
import com.aspose.tasks.OutlineValue;
import com.aspose.tasks.Project;

Now let’s break down the provided example code into multiple steps:

Step 1: Load the Project

String projectName = "ProjectFile.mpp";
Project project = new Project(projectName);

In this step, we load the Microsoft Project file into a Project object using the provided file name.

Step 2: Retrieve Outline Codes

for (OutlineCodeDefinition ocd : project.getOutlineCodes()) {

We iterate through each outline code definition in the project.

Step 3: Access Outline Code Properties

System.out.println("Alias = " + ocd.getAlias());
System.out.println("Field Id = " + ocd.getFieldId());
System.out.println("Field Name = " + ocd.getFieldName());

We retrieve and print various properties of the outline code definition such as Alias, Field ID, and Field Name.

Step 4: Check Enterprise Custom Code

if (ocd.getEnterprise()) {
    System.out.println("It is an enterprise custom outline code.");
} else {
    System.out.println("It is not an enterprise custom outline code.");
}

We check if the outline code is an enterprise custom code and print the result accordingly.

Step 5: Display Outline Code Masks

for (OutlineMask m1 : ocd.getMasks()) {
    System.out.println("Level of a mask = " + m1.getLevel());
    System.out.println("Mask = " + m1.toString());
}

We iterate through each mask associated with the outline code and print its level and mask value.

Step 6: Display Outline Code Values

for (OutlineValue v1 : ocd.getValues()) {
    System.out.println("Description of outline value = " + v1.getDescription());
    System.out.println("Value Id = " + v1.getValueId());
    System.out.println("Value = " + v1.getValue());
    System.out.println("Type = " + v1.getType());
}

We iterate through each outline code value and print its description, value ID, value, and type.

Conclusion

In this tutorial, we have learned how to retrieve MS Project outline codes using Aspose.Tasks for Java. By following the provided steps, you can effectively access and manipulate outline codes in your Java applications, enabling advanced project management capabilities.
