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.

freeBuffers	back to summary
private final void freeBuffers() This method should be called along with (or instead of) normal close. After calling this method, no further reads should be tried. Method will try to recycle read buffers (if any).

getReadCharsCount	back to summary
public int getReadCharsCount()

loadMore	back to summary
private boolean loadMore() throws IOException Returns:boolean True, if enough bytes were read to allow decoding of at least one full character; false if EOF was encountered instead.

read back to summary

read	back 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 Annotations @Override Exceptions IOException: If an I/O error occurs

public int read() throws IOException

read back to summary

read	back to summary
public int read(char[] cbuf) throws IOException Overrides java.io.Reader.read. Doc from java.io.Reader.read. Reads characters into 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 the length of `cbuf` 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 Returns:int The number of characters read, or -1 if the end of the stream has been reached Annotations @Override Exceptions IOException: If an I/O error occurs

public int read(char[] cbuf) throws IOException

Overrides java.io.Reader.read.

Doc from java.io.Reader.read.

Reads characters into 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 the length of cbuf 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

Returns:int

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

read	back to summary
public int read(char[] cbuf, int start, 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 start: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 Annotations @Override Exceptions IOException: If an I/O error occurs

public int read(char[] cbuf, int start, int len) throws IOException

Implements abstract java.io.Reader.read.

Doc from java.io.Reader.read.
