Class org.jruby.embed.io.ReaderInputStream

Examples of org.jruby.embed.io.ReaderInputStream.available()

org.jruby.embed.io.ReaderInputStream.available()
Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream. The next invocation might be the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes.
Note that while some implementations of {@code InputStream} will returnthe total number of bytes in the stream, many will not. It is never correct to use the return value of this method to allocate a buffer intended to hold all data in this stream.
A subclass' implementation of this method may choose to throw an {@link IOException} if this input stream has been closed byinvoking the {@link #close()} method.
The {@code available} method for class {@code InputStream} alwaysreturns {@code 0}. @return an estimate of the number of bytes that can be read (or skippedover) from this input stream without blocking or {@code 0} whenit reaches the end of the input stream. @exception IOException if an I/O error occurs.
