In many cases, a J2EE application cannot directly access the file system on the application server. To allow customers to prepare for this Process Commander capability, the PublicAPI contains Java classes that mimic many features of java.io. Together, these are known as the Virtual File Interface.

The com.pega.pegarules.pub.util Package contains these classes:

• PRFile class — Mimics a subset of methods in java.io.File
• PRInputStream — Emulates java.io.InputStream
• PROutputStream class — Emulates java.io.OutputStream
• PRReader class — Emulates java.io.Reader
• PRWriter class — Emulates java.io.Writer

In Web tier installations of Process Commander, these facilities operate the same as the corresponding java.io facilities.

Consult the PublicAPI JavaDocs for details on these Java classes.
