- All Implemented Interfaces:
public class LazyRandomAccessFileByteReader extends ObjectAn implementation of the ByteReader interface that provides lazy access to a
RandomAccessFile. It will not open the
Fileuntil the first attempt to read or operate on that
File. At that point a
RandomAccessFileByteReaderwill be constructed and used. This class is not threadsafe. It is not safe to pass an instance of this class to multiple threads. It is not safe to pass an instance of this class to multiple users even if in the same thread.
All Methods Instance Methods Concrete Methods Modifier and Type Method Description
ByteReaderand releases any system resources associated with this stream.
length()Returns the number of total bytes in the repository that are visible through this API.
read(long position)Read a single byte from the underlying bytes at the given position.
read(long position, byte b, int offset, int length)Transfers bytes from the underlying repository into the given destination array.
public int read(long position) throws IOExceptionRead a single byte from the underlying bytes at the given position.
public int read(long position, byte b, int offset, int length) throws IOExceptionTransfers bytes from the underlying repository into the given destination array. Copy up to
lengthbytes from the repository starting at the postion given into the given array starting at the given offset.
- Specified by:
position- the position to read the byte from.
b- the array to write the bytes into.
offset- the offset in the array at which the first byte is written.
length- the maximum number of bytes to write into the array.
- the number of bytes actually written to the array.
IOException- if an error occurs during the read operation
