Managing Resource Extended Attributes

Extending Resource Attributes The ExtendedAttribute property exposed by the Resource class can be used to manage the extended attributes of a resource. This property reads and writes an ArrayList of the ExtendedAttribute objects to deal with a resource’s extended attributes. The ExtendedAttribute object further exposes the relevant properties.

The following example shows how to set a resource’s extended attributes.

// The path to the documents directory.
String dataDir = Utils.getDataDir(ExtendedResourceAttributes.class);

Project prj = new Project(dataDir + "project5.mpp");

// Define extended attribute
ExtendedAttributeDefinition myNumber1 = prj.getExtendedAttributes()
        .getById((int) ExtendedAttributeTask.Number1);
if (myNumber1 == null) {
    myNumber1 = ExtendedAttributeDefinition.createResourceDefinition(ExtendedAttributeResource.Number1, "Age");
    prj.getExtendedAttributes().add(myNumber1);
}

// Create extended attribute and set its value
ExtendedAttribute number1Resource = myNumber1.createExtendedAttribute();
number1Resource.setNumericValue(BigDecimal.valueOf(30.5345));

// Add a new resource and its extended attribute
Resource rsc = prj.getResources().add("R1");
rsc.getExtendedAttributes().add(number1Resource);

prj.save(dataDir + "Project5.xml", SaveFileFormat.XML);

// Display result of conversion.
