Examples of org.antlr.runtime.ANTLRFileStream

org.antlr.runtime.ANTLRFileStream
This is a char buffer stream that is loaded from a file all at once when you construct the object. This looks very much like an ANTLReader or ANTLRInputStream, but it's a special case since we know the exact size of the object to load. We can avoid lots of data copying.
