Creates a piped input stream that is not yet connected to a piped output stream. It must be connected to a piped output stream, either by the receiver (I-§2.16.4) or the sender (I-§2.17.4), before being used.

Creates a piped input stream connected to the specified piped output stream.

Parameters:

src - the stream to connect to.

Throws

IOException (I-§2.29)

If an I/O error occurs.

Closes this piped input stream and releases any system resources associated with the stream.

Throws

IOException (I-§2.29)

If an I/O error occurs.

Overrides:

close in class InputStream (I-§2.13.3).

Connects this piped input stream to a sender.

Parameters:

src - The piped output stream to connect to.

Throws

IOException (I-§2.29)

If an I/O error occurs.

Reads the next byte of data from this piped input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because this end of the stream has been reached, the value -1 is returned. This method blocks until either input data is available, the end of the stream is detected, or an exception is thrown.

Returns:

the next byte of data, or -1 if the end of the stream is reached.

Throws

IOException (I-§2.29)

If the pipe is broken.

Overrides:

read in class InputStream (I-§2.13.6).

Reads up to len bytes of data from this piped input stream into an array of bytes. This method blocks until at least one byte of input is available.

Parameters:

b - the buffer into which the data is read

off - the start offset of the data

len - the maximum number of bytes read

Returns:

the total number of bytes read into the buffer, or -1 is there is no more data because the end of the stream has been reached.

Throws

IOException (I-§2.29)

If an I/O error occurs.

Overrides:

read in class InputStream (I-§2.13.8).
