public class BinaryInPort
extends InPort

An InPort that wraps an InputStream using straight-through copying. This is an optimization of using Latin-1 conversion.

Method Detail

fill

protected int fill(int len)
            throws java.io.IOException

Description copied from class: LineBufferedReader

Called by read() when it needs its buffer filled. Read characters into buffer, starting at pos, for len. Can assume that len > 0. Only called if pos>=limit. Return -1 if EOF, otherwise number of read chars. This can be usefully overridden by sub-classes.

Overrides:

fill in class LineBufferedReader

Throws:

java.io.IOException

readByte

public int readByte()
             throws java.io.IOException

Throws:

java.io.IOException

peekByte

public int peekByte()
             throws java.io.IOException

Throws:

java.io.IOException

readBytes

public int readBytes(byte[] buf,
                     int offset,
                     int count)
              throws java.io.IOException

Throws:

java.io.IOException

readByteVector

public int readByteVector(ByteVector bvector,
                          int offset,
                          int count)
                   throws java.io.IOException

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class LineBufferedReader

Throws:

java.io.IOException

sourceReady

protected boolean sourceReady()
                       throws java.io.IOException

Overrides:

sourceReady in class LineBufferedReader

Throws:

java.io.IOException

openFile

public static BinaryInPort openFile(java.lang.Object fname)
                             throws java.io.IOException

Throws:

java.io.IOException
