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.

IOException:

markback to summary
public void mark(int readAheadLimit) throws IOException

Overrides java.io.Reader.mark.

Doc from java.io.Reader.mark.

Marks the present position in the stream. Subsequent calls to reset() will attempt to reposition the stream to this point. Not all character-input streams support the mark() operation.

Parameters
readAheadLimit:int

Limit on the number of characters that may be read while still preserving the mark. After reading this many characters, attempting to reset the stream may fail.

Annotations
@Override
Exceptions
IOException:
If the stream does not support mark(), or if some other I/O error occurs
markSupportedback to summary
public boolean markSupported()

Overrides java.io.Reader.markSupported.

Doc from java.io.Reader.markSupported.

Tells whether this stream supports the mark() operation. The default implementation always returns false. Subclasses should override this method.

Returns:boolean

true if and only if this stream supports the mark operation.

Annotations
@Override
readback to summary
public int read() throws IOException

Overrides java.io.Reader.read.

Doc from java.io.Reader.read.

Reads a single character. This method will block until a character is available, an I/O error occurs, or the end of the stream is reached.

Subclasses that intend to support efficient single-character input should override this method.

Returns:int

The character read, as an integer in the range 0 to 65535 (0x00-0xffff), or -1 if the end of the stream has been reached

Exceptions
IOException:
If an I/O error occurs
readback to summary
public int read(char[] dest, 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
dest: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

IOException:

resetback to summary
public void reset()

Overrides java.io.Reader.reset.

Doc from java.io.Reader.reset.

Resets the stream. If the stream has been marked, then attempt to reposition it at the mark. If the stream has not been marked, then attempt to reset it in some way appropriate to the particular stream, for example by repositioning it to its starting point. Not all character-input streams support the reset() operation, and some support reset() without supporting mark().

skipback to summary
public long skip(long n)

Overrides java.io.Reader.skip.

Doc from java.io.Reader.skip.

Skips characters. This method will block until some characters are available, an I/O error occurs, or the end of the stream is reached. If the stream is already at its end before this method is invoked, then no characters are skipped and zero is returned.

Parameters
n:long

The number of characters to skip

Returns:long

The number of characters actually skipped
