RandomAccessIO Interface

This abstract class defines the interface to perform random access I/O. It implements the BinaryDataInput and BinaryDataOutput interfaces so that binary data input/output can be performed.

       <p>This interface supports streams of up to 2 GB in length.</p>

Namespace: CSJ2K.j2k.io

Assembly: C1.WPF.ReportViewer.4.6.2.dll

Syntax

public interface RandomAccessIO : BinaryDataInput, BinaryDataOutput

Public Interface RandomAccessIO
    Inherits BinaryDataInput, BinaryDataOutput

Properties

Name	Description
Pos	Returns the current position in the stream, which is the position from where the next byte of data would be read. The first byte in the stream is in position `0`.

Methods

Name	Description
close()	Closes the I/O stream. Prior to closing the stream, any buffered data (at the bit and byte level) should be written.
length()	Returns the current length of the stream, in bytes, taking into account any buffering.
read()	Reads a byte of data from the stream. Prior to reading, the stream is realigned at the byte level.
readFully(byte[], int, int)	Reads up to len bytes of data from this file into an array of bytes. This method reads repeatedly from the stream until all the bytes are read. This method blocks until all the bytes are read, the end of the stream is detected, or an exception is thrown.
seek(int)	Moves the current position for the next read or write operation to offset. The offset is measured from the beginning of the stream. The offset may be set beyond the end of the file, if in write mode. Setting the offset beyond the end of the file does not change the file length. The file length will change only by writing after the offset has been set beyond the end of the file.
write(byte)	Writes a byte to the stream. Prior to writing, the stream is realigned at the byte level.
