PipedReader JDK 1.6)

Constructors

public PipedReader ()

Creates a PipedReader so that it is not yet connected.

Creates a PipedReader so
that it is not yet connected. It must be connected to a PipedWriter
before being used.

public PipedReader (int pipeSize)

Creates a PipedReader so that it is not yet connected and uses the specified pipe size for the pipe's buffer.

Creates a PipedReader so that it is not yet
connected and uses
the specified pipe size for the pipe's buffer.
It must be connected to a PipedWriter
before being used.
Parameters:
- pipeSize - the size of the pipe's buffer.
Throws:
- IllegalArgumentException - if pipeSize <= 0.
Since: 1.6

public PipedReader (PipedWriter src) throws IOException

Creates a PipedReader so that it is connected to the piped writer src.

Creates a PipedReader so
that it is connected to the piped writer
src. Data written to src
will then be available as input from this stream.
Parameters:
- src - the stream to connect to.
Throws:
- IOException - if an I/O error occurs.

public PipedReader (PipedWriter src, int pipeSize) throws IOException

Creates a PipedReader so that it is connected to the piped writer src and uses the specified pipe size for the pipe's buffer.

Creates a PipedReader so that it is connected
to the piped writer src and uses the specified
pipe size for the pipe's buffer. Data written to src
will then be available as input from this stream.
Parameters:
- src - the stream to connect to.
- pipeSize - the size of the pipe's buffer.
Throws:
- IOException - if an I/O error occurs.
- IllegalArgumentException - if pipeSize <= 0.
Since: 1.6

Methods

Hide/Show inherited methods

public void close () throws IOException [Specified in Reader]

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

public void connect (PipedWriter src) throws IOException

Causes this piped reader to be connected to the piped writer src.

Causes this piped reader to be connected to the piped writer src. If this object is already connected to some other piped writer, an IOException is thrown.

If src is an unconnected piped writer and snk is an unconnected piped reader, they may be connected by either the call:

snk.connect(src)

or the call:

src.connect(snk)

The two calls have the same effect.
Parameters:
- src - The piped writer to connect to.
Throws:
- IOException - if an I/O error occurs.

public void mark (int readAheadLimit) throws IOException [Inherited From Reader]

Marks the present position in the stream.

public boolean markSupported () [Inherited From Reader]

Tells whether this stream supports the mark() operation.

publicsynchronized int read () throws IOException [Overrides Reader]

Reads the next character of data from this piped stream.

Reads the next character of data from this piped stream.
If no character is available because the end of the stream
has been reached, the value -1 is returned.
This method blocks until input data is available, the end of
the stream is detected, or an exception is thrown.
Returns: the next character of data, or -1 if the end of the stream is reached.
Throws:
- IOException - if the pipe is broken, {@link #connect(java.io.PipedWriter) unconnected}, closed, or an I/O error occurs.

public int read (char[] cbuf) throws IOException [Inherited From Reader]

Reads characters into an array.

publicsynchronized int read (char[] cbuf, int off, int len) throws IOException [Specified in Reader]

Reads up to len characters of data from this piped stream into an array of characters.

Reads up to len characters of data from this piped
stream into an array of characters. Less than len characters
will be read if the end of the data stream is reached or if
len exceeds the pipe's buffer size. This method
blocks until at least one character of input is available.
Returns: the total number of characters read into the buffer, or -1 if there is no more data because the end of the stream has been reached.
Parameters:
- cbuf - the buffer into which the data is read.
- off - the start offset of the data.
- len - the maximum number of characters read.
Throws:
- IOException - if the pipe is broken, {@link #connect(java.io.PipedWriter) unconnected}, closed, or an I/O error occurs.

public int read (CharBuffer target) throws IOException [Inherited From Reader]

Attempts to read characters into the specified character buffer.

publicsynchronized boolean ready () throws IOException [Overrides Reader]

Tell whether this stream is ready to be read.

pack-privatesynchronized void receive (char[] c, int off, int len) throws IOException

Receives data into an array of characters.

pack-privatesynchronized void receive (int c) throws IOException

Receives a char of data.

pack-privatesynchronized void receivedLast ()

Notifies all waiting threads that the last character of data has been received.

public void reset () throws IOException [Inherited From Reader]

Resets the stream.

public long skip (long n) throws IOException [Inherited From Reader]

Skips characters.

Skips characters. This method will block until some characters are
available, an I/O error occurs, or the end of the stream is reached.
Returns: The number of characters actually skipped
Parameters:
- n - The number of characters to skip
Throws:
- IllegalArgumentException - If n is negative.
- IOException - If an I/O error occurs
