public void close() throws IOException Implements abstract java.io.Reader.close. Implements java.io.Closeable.close. Doc from java.io.Reader.close.

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.

read back to summary

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

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

ready	back to summary
public boolean ready() throws IOException Overrides java.io.Reader.ready. Doc from java.io.Reader.ready. Tells whether this stream is ready to be read. Returns:boolean 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.

ready

public boolean ready() throws IOException

Overrides java.io.Reader.ready.

Doc from java.io.Reader.ready.

Tells whether this stream is ready to be read.

Returns:boolean

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.

skip	back to summary
public long skip(long n) throws IOException 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 Annotations @Override Exceptions IOException: If an I/O error occurs

skip

public long skip(long n) throws IOException

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
