java.lang.Object
  org.apache.lucene.store.InputStream
      org.apache.lucene.index.CompoundFileReader.CSInputStream

All Implemented Interfaces:

java.lang.Cloneable

Enclosing class:

CompoundFileReader

---

static final class CompoundFileReader.CSInputStream

extends org.apache.lucene.store.InputStream

Implementation of an InputStream that reads from a portion of the compound file. The visibility is left as "package" *only* because this helps with testing since JUnit test cases in a different class can then access package fields of this class.
