creating pdf/a files with adobe acrobat sdk ( Java )

Greetings, I want to create a pdf/a complaint pdf file using acrobat sdk, I am refering to the sample code available in the official documentation and github repository. I didn't find any specific apis to set pdf/a properties to pdf document. Is there any api available to set the conformancelevel of the generating pdf file. 

The package I am using in pom.xml:

<dependency>
<groupId>com.adobe.documentservices</groupId>
<artifactId>pdfservices-sdk</artifactId>
<version>4.0.0</version>
</dependency>

link to sample code from adobe: click here 
Thanks in Advance.
