Class FastPushbackBufferedReader

java.lang.Object

java.io.Reader

java.io.BufferedReader

com.cedarsoftware.util.io.FastPushbackBufferedReader

All Implemented Interfaces:

FastPushbackReader, Closeable, AutoCloseable, Readable

public class FastPushbackBufferedReader
extends BufferedReader
implements FastPushbackReader

This class adds significant performance increase over using the JDK PushbackReader. This is due to this class not using synchronization as it is not needed.

All custom writers for json-io subclass this class. Special writers are not needed for handling user-defined classes. However, special writers are built/supplied by json-io for many of the primitive types and other JDK classes simply to allow for a more concise form.
