Class RandomAccessStream
java.lang.Object
java.io.InputStream
ij.io.RandomAccessStream
- All Implemented Interfaces:
- java.io.Closeable
public final class RandomAccessStream
- extends java.io.InputStream
This is a class that uses a memory cache to allow seeking within
an InputStream. Based on the JAI MemoryCacheSeekableStream class.
Can also be constructed from a RandomAccessFile, which uses less
memory since the memory cache is not required.
