Class MergedStream

java.lang.Object
  java.io.InputStream
      com.ctc.wstx.io.MergedStream

public final class MergedStream

extends java.io.InputStream

Simple InputStream implementation that is used to "unwind" some data previously read from an input stream; 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 stream. This is similar to PushbackInputStream, but here there's only one implicit pushback, when instance is constructed.
