Class ANTLRReaderStream

java.lang.Object

org.antlr.runtime.ANTLRStringStream

org.antlr.runtime.ANTLRReaderStream

All Implemented Interfaces:

CharStream, IntStream

Direct Known Subclasses:

ANTLRInputStream

public class ANTLRReaderStream
extends ANTLRStringStream

Vacuum all input from a Reader and then treat it like a StringStream. Manage the buffer manually to avoid unnecessary data copying. If you need encoding, use ANTLRInputStream.
