Class MergedReader

java.lang.Object

java.io.Reader

com.ctc.wstx.io.MergedReader

All Implemented Interfaces:

Closeable, AutoCloseable, Readable

public final class MergedReader
extends Reader

Simple Reader implementation that is used to "unwind" some data previously read from a Reader; so that as long as some of that data remains, it's returned; but as long as it's read, we'll just use data from the underlying original Reader. This is similar to PushbackReader, but with this class there's only one implicit pushback, when instance is constructed; not general pushback buffer and methods to use it.
