	Object	clone()
		Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
	boolean	equals(Object o)
		Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
	void	finalize()
		Called by the virtual machine when there are no longer any (non-weak) references to the receiver.
final	Class	getClass()
		Answers the unique instance of java.lang.Class which represents the class of the receiver.
	int	hashCode()
		Answers an integer hash code for the receiver.
final	void	notify()
		Causes one thread which is `wait` ing on the receiver to be made ready to run.
final	void	notifyAll()
		Causes all threads which are `wait` ing on the receiver to be made ready to run.
	String	toString()
		Answers a string containing a concise, human-readable description of the receiver.
final	void	wait(long time, int frac)
		Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by `notify` or `notifyAll`) or the expiration of the timeout.
final	void	wait(long time)
		Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by `notify` or `notifyAll`) or the expiration of the timeout.

Public Constructors

public BufferedWriter(Writer out)

Constructs a new BufferedReader with out as the Writer on which to buffer write operations. The buffer size is set to the default, which is 8K.

Parameters

out	The Writer to buffer character writing on

public BufferedWriter(Writer out, int size)

Constructs a new BufferedReader with out as the Writer on which buffer write operations. The buffer size is set to size.

Parameters

out	The Writer to buffer character writing on.
size	The size of the buffer to use.

Public Methods

public void close()

Close this BufferedWriter. The contents of the buffer are flushed, the target writer is closed, and the buffer is released. Only the first invocation of close has any effect.

Throws

IOException	If an error occurs attempting to close this Writer.

public void flush()

Flush this BufferedWriter. The contents of the buffer are committed to the target writer and it is then flushed.

Throws

IOException	If an error occurs attempting to flush this Writer.

public void newLine()

Write a newline to thie Writer. A newline is determined by the System property "line.separator". The target writer may or may not be flushed when a newline is written.

Throws

IOException	If an error occurs attempting to write to this Writer.

public void write(char[] cbuf, int offset, int count)

Writes out count characters starting at offset in buf to this BufferedWriter. If count is greater than this Writers buffer then flush the contents and also write the characters directly to the target Writer.

Parameters

cbuf	the non-null array containing characters to write.
offset	offset in buf to retrieve characters
count	maximum number of characters to write

Throws

IOException	If this Writer has already been closed or some other IOException occurs.
IndexOutOfBoundsException	If offset or count are outside of bounds.

public void write(String str, int offset, int count)

Writes out count characters starting at offset in str to this BufferedWriter. If count is greater than this Writers buffer then flush the contents and also write the characters directly to the target Writer.

Parameters

str	the non-null String containing characters to write
offset	offset in str to retrieve characters
count	maximum number of characters to write

Throws

IOException	If this Writer has already been closed or some other IOException occurs.
ArrayIndexOutOfBoundsException	If offset or count are outside of bounds.

public void write(int oneChar)

Writes the character oneChar BufferedWriter. If the buffer is filled by writing this character, flush this Writer. Only the lower 2 bytes are written.

Parameters

oneChar	The Character to write out.

Throws

IOException	If this Writer has already been closed or some other IOException occurs.

	Writer	append(CharSequence csq)
		Append a CharSequence `csq` to the Writer.
	Writer	append(CharSequence csq, int start, int end)
		Append a subsequence of a CharSequence `csq` to the Writer.
	Writer	append(char c)
		Append a char `c`to the Writer.
abstract	void	close()
		Close this Writer.
abstract	void	flush()
		Flush this Writer.
abstract	void	write(char[] buf, int offset, int count)
		Writes `count` characters starting at `offset in buf to this Writer.`
	void	write(String str, int offset, int count)
		Writes `count` number of characters starting at `offset` from the String `str` to this Writer.
	void	write(int oneChar)
		Writes the specified character `oneChar` to this Writer.
	void	write(char[] buf)
		Writes the entire character buffer `buf` to this Writer.
	void	write(String str)
		Writes the characters from the String `str` to this Writer.

				Appendable	append(CharSequence csq)
					Append the given `CharSequence`.
				Appendable	append(CharSequence csq, int start, int end)
					Append part of the given `CharSequence`.
				Appendable	append(char c)
					Append the given character.
