| Field Summary | |
| protected char | buf
The buffer where data is stored. | | protected int | count
The number of chars in the buffer. |
| Constructor Summary | |
| public | CharArrayWriter()
Creates a new CharArrayWriter. | | public | CharArrayWriter(int initialSize)
Creates a new CharArrayWriter with the specified initial size. |
| Method Summary | |
| public void | close()
Close the stream. | | public void | flush()
Flush the stream. | | public void | reset()
Resets the buffer so that you can use it again without
throwing away the already allocated buffer. | | public int | size()
Returns the current size of the buffer. | | public char | toCharArray()
Returns a copy of the input data. | | public String | toString()
Converts input data to a string. | | public void | write(int c)
Writes a character to the buffer. | | public void | write(char c, int off, int len)
Writes characters to the buffer. | | public void | write(String str, int off, int len)
Write a portion of a string to the buffer. | | public void | writeTo(Writer out)
Writes the contents of the buffer to another character stream. |
| buf | | protected char buf(Code) | | The buffer where data is stored.
|
| count | | protected int count(Code) | | The number of chars in the buffer.
|
| CharArrayWriter | | public CharArrayWriter()(Code) | | Creates a new CharArrayWriter.
|
| CharArrayWriter | | public CharArrayWriter(int initialSize)(Code) | | Creates a new CharArrayWriter with the specified initial size.
Parameters:
initialSize - an int specifying the initial buffer size.
exception:
IllegalArgumentException - if initialSize is negative |
| close | | public void close()(Code) | | Close the stream. This method does not release the buffer, since its
contents might still be required.
|
| flush | | public void flush()(Code) | | Flush the stream.
|
| reset | | public void reset()(Code) | | Resets the buffer so that you can use it again without
throwing away the already allocated buffer.
|
| size | | public int size()(Code) | | Returns the current size of the buffer.
an int representing the current size of the buffer. |
| toCharArray | | public char toCharArray()(Code) | | Returns a copy of the input data.
an array of chars copied from the input data. |
| toString | | public String toString()(Code) | | Converts input data to a string.
the string. |
| write | | public void write(int c)(Code) | | Writes a character to the buffer.
|
| write | | public void write(char c, int off, int len)(Code) | | Writes characters to the buffer.
Parameters:
c - the data to be written
Parameters:
off - the start offset in the data
Parameters:
len - the number of chars that are written |
| write | | public void write(String str, int off, int len)(Code) | | Write a portion of a string to the buffer.
Parameters:
str - String to be written from
Parameters:
off - Offset from which to start reading characters
Parameters:
len - Number of characters to be written |
| writeTo | | public void writeTo(Writer out) throws IOException(Code) | | Writes the contents of the buffer to another character stream.
Parameters:
out - the output stream to write to
throws:
IOException - If an I/O error occurs. |
