Method Detail

closeback to summary
public void close() throws IOException

Implements abstract java.io.Reader.close.

Implements java.io.Closeable.close.

Doc from java.io.Reader.close.

Closes the stream and releases any system resources associated with it. Once the stream has been closed, further read(), ready(), mark(), reset(), or skip() invocations will throw an IOException. Closing a previously closed stream has no effect.

Exceptions
IOException:
If an I/O error occurs
getEncodingback to summary
public String getEncoding()

Get stream encoding or NULL if stream is uninitialized. Call init() or read() method to initialize it.

Returns:String

the name of the character encoding being used by this stream.

initback to summary
protected void init() throws IOException

Read-ahead four bytes and check for BOM marks. Extra bytes are unread back to the stream, only BOM bytes are skipped.

Exceptions
IOException:
if InputStream cannot be created
readback to summary
public int read(char[] cbuf, int off, int len) throws IOException

Implements abstract java.io.Reader.read.

Doc from java.io.Reader.read.

Reads characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.

If len is zero, then no characters are read and 0 is returned; otherwise, there is an attempt to read at least one character. If no character is available because the stream is at its end, the value -1 is returned; otherwise, at least one character is read and stored into cbuf.

Parameters
cbuf:char[]

Destination buffer

off:int

Offset at which to start storing characters

len:int

Maximum number of characters to read

Returns:int

The number of characters read, or -1 if the end of the stream has been reached

Exceptions
IOException:
If an I/O error occurs
