CaseInsensitiveANTLRStringStream

java.lang.Object
- org.eclipse.persistence.internal.libraries.antlr.runtime.ANTLRStringStream
- - org.eclipse.persistence.internal.jpa.parsing.jpql.CaseInsensitiveANTLRStringStream

All Implemented Interfaces:

org.eclipse.persistence.internal.libraries.antlr.runtime.CharStream, org.eclipse.persistence.internal.libraries.antlr.runtime.IntStream
```
public class CaseInsensitiveANTLRStringStream
extends org.eclipse.persistence.internal.libraries.antlr.runtime.ANTLRStringStream
```
This Stream is used when tokenizing JPQL queries It overrides the look ahead operator to return the lower case version of the string This is required because starting in ANTLR v3, case insensitivity is not provided as an option in ANTLR and JPQL requires case insensitivity
