jdk.io.PipedReader — clojure-interop/java.io 1.0.5

Piped character-input streams.

->piped-reader clj

(->piped-reader)

(->piped-reader src)

(->piped-reader src pipe-size)

Constructor.

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.

src - the stream to connect to. - java.io.PipedWriter pipe-size - the size of the pipe's buffer. - int

throws: java.io.IOException - if an I/O error occurs.

close clj

(close this)

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

throws: java.io.IOException - if an I/O error occurs.

connect clj

(connect this 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.

src - The piped writer to connect to. - java.io.PipedWriter

throws: java.io.IOException - if an I/O error occurs.

read clj

(read this)

(read this cbuf off len)

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.

cbuf - the buffer into which the data is read. - char[] off - the start offset of the data. - int len - the maximum number of characters read. - int

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. - int

throws: java.io.IOException - if the pipe is broken, unconnected, closed, or an I/O error occurs.

ready clj

(ready this)

Tell whether this stream is ready to be read. A piped character stream is ready if the circular buffer is not empty.

returns: True if the next read() is guaranteed not to block for input, false otherwise. Note that returning false does not guarantee that the next read will block. - boolean

throws: java.io.IOException - if the pipe is broken, unconnected, or closed.
