public class CharArrayWriter
extends Writer
This class implements a character buffer that can be used as an Writer. The buffer automatically grows when data is written to the stream. The data can be retrieved using toCharArray() and toString().

Variable Index

o buf
The buffer where data is stored.
o count
The number of chars in the buffer.

Constructor Index

o CharArrayWriter()
Creates a new CharArrayWriter.
o CharArrayWriter(int)
Creates a new CharArrayWriter with the specified initial size.

Method Index

o close()
Close the stream.
o flush()
Flush the stream.
o reset()
Resets the buffer so that you can use it again without throwing away the already allocated buffer.
o size()
Returns the current size of the buffer.
o toCharArray()
Returns a copy of the input data.
o toString()
Converts input data to a string.
o write(char[], int, int)
Writes characters to the buffer.
o write(int)
Writes a character to the buffer.
o write(String, int, int)
Write a portion of a string to the buffer.
o writeTo(Writer)
Writes the contents of the buffer to another character stream.

Variables

o buf 
 protected char buf[]
The buffer where data is stored.

o count 
 protected int count
The number of chars in the buffer.

Constructors

o CharArrayWriter 
 public CharArrayWriter()
Creates a new CharArrayWriter.

o CharArrayWriter 
 public CharArrayWriter(int initialSize)
Creates a new CharArrayWriter with the specified initial size.

Methods

o write 
 public void write(int c)
Writes a character to the buffer.

Overrides:
write in class Writer
o write 
 public void write(char c[],
                   int off,
                   int len)
Writes characters to the buffer.

Parameters:
c - the data to be written

o write 
 public void write(String str,
                   int off,
                   int len)
Write a portion of a string to the buffer.

Parameters:
str - String to be written from
off - Offset from which to start reading characters
len - Number of characters to be written
Overrides:
write in class Writer
o writeTo 
 public void writeTo(Writer out) throws IOException
Writes the contents of the buffer to another character stream.

Parameters:
out - the output stream to write to
o reset 
 public void reset()
Resets the buffer so that you can use it again without throwing away the already allocated buffer.

o toCharArray 
 public char[] toCharArray()
Returns a copy of the input data.

o size 
 public int size()
Returns the current size of the buffer.

o toString 
 public String toString()
Converts input data to a string.

Returns:
the string.
Overrides:
toString in class Object
o flush 
 public void flush()
