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

```
public void write(char[] c,
                  int off,

```
    Writes characters to the buffer.
    
    定義:
    
    write クラス内 Writer
    
    パラメータ:
    
    c - the data to be written
    
    off - the start offset in the data
    
    len - the number of chars that are written
  - write
```
public void write(String str,
                  int off,
                  int len)
```
    Write a portion of a string to the buffer.
    
    オーバーライド:
    
    write クラス内 Writer
    
    パラメータ:
    
    str - String to be written from
    
    off - Offset from which to start reading characters
    
    len - Number of characters to be written
  - writeTo
```
public void writeTo(Writer out)
             throws IOException
```
    Writes the contents of the buffer to another character stream.
    
    パラメータ:
    
    out - the output stream to write to
    
    例外:
    
    IOException - If an I/O error occurs.
  - append
```
public FastCharArrayWriter append(CharSequence csq)
```
    Appends the specified character sequence to this writer.
    An invocation of this method of the form out.append(csq) behaves in exactly the same way as the invocation
```
     out.write(csq.toString()) 
```
    Depending on the specification of toString for the character sequence csq, the entire sequence may not be appended. For instance, invoking the toString method of a character buffer will return a subsequence whose content depends upon the buffer's position and limit.

```
    Appends a subsequence of the specified character sequence to this writer.
    An invocation of this method of the form out.append(csq, start, end) when csq is not null, behaves in exactly the same way as the invocation
