public final class MergedStream extends java.io.InputStream
SimpleInputStream
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 toPushbackInputStream
, but here there's only one implicit pushback, when instance is constructed.
