## com.fasterxml.jackson.core.io
Class MergedStream

    java.lang.Object
      java.io.InputStream
          com.fasterxml.jackson.core.io.MergedStream

All Implemented Interfaces:
  Closeable

    public final class MergedStream

extends 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.
