All Implemented Interfaces:

Visitor

public class StringInterner
extends AbstractSimpleVisitor

A Visitor that interns String attribute values.

Strings are interned using the standard String.intern() method. If working with large class model objects, then it is advisable (for maximum performance) to configure the size of the string pool beforehand using JVM options -XX:MaxPermSize (Java 1.6) or -XX:StringTableSize (Java 1.7 and newer). For more information, see String.intern in Java 6, 7 and 8 – string pooling.
