Setting attribute values

Hello,

I am uploading a document to a folder that contains metadata consisting of a group of categories with different attributes each.

To set the metadata of the document being uploaded, i am reading the metadata off of the parent folder and then attempting to set the values for the attributes in the metadata object before uploading the document. This is not working. i.e. I don't have any set methods on any of these objects: AttributeGroup, DateValue nor StringValue. (BTW, i am using the java api)

How do i set attribute values for a document being uploaded ? also

how do set an attribute value if the attribute contains a list of pre-defined values ?

Appreciate your response.

Thanks

Hi, Amir.

I think this excerpt will take care of what you're trying to do:

        SimpleDateFormat sdf = new SimpleDateFormat( "yyyyMMddHHmmss" );

        // Get the category definition and the definition of the first attribute.
        // In this case, the category has a single text popup attribute.
        AttributeGroupDefinition catDefn = fDocManSvc.getCategoryDefinition( catID );
        StringAttribute textPopupDefn = (StringAttribute) catDefn.getAttributes().get( 0 );

        // Get a template for the category and the StringValue object for our
        // text popup attribute.
        AttributeGroup attrGroup = fDocManSvc.getCategoryTemplate( catID );
        StringValue textPopup = (StringValue) attrGroup.getValues().get( 0 );

        // Set the attribute to the third option
        textPopup.getValues().add( textPopupDefn.getValidValues().get( 2 ) );

        // Create an instance of Metadata and assign our AttributeGroup to it.
        Metadata metadata = new Metadata();
        metadata.getAttributeGroups().add( attrGroup );

        // Create an object using our category data.
        fDocManSvc.createFolder(
                2000,
                "CatAttTestFolder" + sdf.format( new Date() ),
                null,
                metadata );

Basically, use GetCategoryTemplate() when using it for the metadata of an object. If you need information about the definition of the Category (like popup values), use GetCategoryDefinition().

Hope this helps.

Hi Scott,

Thanks for your reply. The code snippet assumes you know of the category id. My question was, if i have a node with a set of metadata, how do i assign values to the attributes that make up the metadata?

i was able to determine how to do it by using the following snippet (i am not using docman)

...

Metadata updatedMetadata = node.getMetadata() ;

List<AttributeGroup> attributeGroups = updatedMetadata.getAttributeGroups() ;

String anAttributeValue = "test" ;

// go through all the categories

for (AttributeGroup currAttribGroup: attributeGroups) {

// get the display name of the current attribute

currCategoryName = currAttribGroup.getDisplayName() ;

// set the value of each attribute

for (DataValue currDataValue: currAttribGroup.getValues()) {

currAttributeName = currDataValue.getDescription() ;

if (currDataValue instanceof StringValue) {

StringValue strValue = (StringValue)currDataValue ;

if (strValue.getValues() != null && strValue.getValues().size() > 0)

strValue.getValues().set(0, anAttributeValue) ;

else

strValue.getValues().add(anAttributeValue) ;

}

....

But your post helped explained the difference between GetCategoryTemplate() and GetCategoryDefinition().

Having said that I still have one question.

I have setup a Date attribute with no default values. In the java code, it has one entry with a null value? all other attribute types (Text filed, Text popup) have no elements when invoking their coresponding object's getValues() function?

Why is that ?

Thanks

Hi, Amir.

I see the same behaviour that you're seeing. I'll have to look into it further.

Thanks,

Hi, Amir.

This issue has to do with the fact that the StringAttribute SDO's Values property has elements that are not nillable whereas the DateAttribute SDO's Values property has nillable elements. The root of this discrepancy has to do with limitations at the time with JAX-WS's handling of nillable strings in the WSDL.

MultiLineAttribute will have the same behaviour as it also deals with strings.

Thanks,

Scott
