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().

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

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

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

buf


 protected char buf[]

The buffer where data is stored.

count


 protected int count

The number of chars in the buffer.

CharArrayWriter


 public CharArrayWriter()

Creates a new CharArrayWriter.

CharArrayWriter


 public CharArrayWriter(int initialSize)

Creates a new CharArrayWriter with the specified initial size.

write


 public void write(int c)

Writes a character to the buffer.

Overrides:: write in class Writer

write


 public void write(char c[],
                   int off,
                   int len)

Writes characters to the buffer.

Parameters:: c - the data to be written; off - the start offset in the data; len - the number of chars that are written
Overrides:: write in class Writer

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

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

reset


 public void reset()

Resets the buffer so that you can use it again without throwing away the already allocated buffer.

toCharArray


 public char[] toCharArray()

Returns a copy of the input data.

size


 public int size()

Returns the current size of the buffer.

toString


 public String toString()

Converts input data to a string.

Returns:: the string.
Overrides:: toString in class Object

flush


 public void flush()

Flush the stream.

Overrides:: flush in class Writer

close


 public void close()

Close the stream. This method does not release the buffer, since its contents might still be required.
