Method Detail

fill

protected abstract void fill(int requestedBytes)
                      throws java.io.IOException

Called when more bytes need to be written into this stream (as an OutputStream). This method must write at least one byte if the stream is not ended, and it must not write any bytes if the stream has already ended.

Throws:

java.io.IOException

getOutputStream

public final java.io.OutputStream getOutputStream()

Returns the linked output stream. This is the output stream that must be written to whenever the fill method is called.

read

public int read()
         throws java.io.IOException

Specified by:

read in class java.io.InputStream

Throws:

java.io.IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException

Read characters into a portion of an array, reading from the underlying stream at most once if necessary.

Overrides:

read in class java.io.InputStream

Throws:

java.io.IOException

skip

public long skip(long n)
          throws java.io.IOException

Overrides:

skip in class java.io.InputStream

Throws:

java.io.IOException

available

public int available()

Overrides:

available in class java.io.InputStream

mark

public void mark(int readlimit)

Overrides:

mark in class java.io.InputStream

reset

public void reset()
           throws java.io.IOException

Overrides:

reset in class java.io.InputStream

Throws:

java.io.IOException

markSupported

public boolean markSupported()

Overrides:

markSupported in class java.io.InputStream
