Field Detail

### bufferSize

    protected int bufferSize

Constructor Detail

### BodyContentImpl

    public BodyContentImpl(javax.servlet.jsp.JspWriter writer)

Method Detail

### write

    public void write(int c)
               throws java.io.IOException

  Write a single character.

  Overrides:
    `write` in class `java.io.Writer`
    `java.io.IOException`

### write

    public void write(char[] cbuf,
                      int off,
                      int len)
               throws java.io.IOException

  Write a portion of an array of characters.

  Ordinarily this method stores characters from the given array into this stream's buffer, flushing the buffer to the underlying stream as needed. If the requested length is at least as large as the buffer, however, then this method will flush the buffer and write the characters directly to the underlying stream. Thus redundant `DiscardableBufferedWriter`s will not copy data unnecessarily.

  Specified by:
    `write` in class `java.io.Writer`
  Parameters:
    `cbuf` - A character array
    `off` - Offset from which to start reading characters
    `len` - Number of characters to write
    `java.io.IOException`

### write

    public void write(char[] buf)
               throws java.io.IOException

  Write an array of characters. This method cannot be inherited from the Writer class because it must suppress I/O exceptions.

  Overrides:
    `write` in class `java.io.Writer`
    `java.io.IOException`

### write

    public void write(java.lang.String s,
                      int off,
                      int len)
               throws java.io.IOException

  Write a portion of a String.

  Overrides:
    `write` in class `java.io.Writer`
  Parameters:
    `s` - String to be written
    `off` - Offset from which to start reading characters
    `len` - Number of characters to be written
    `java.io.IOException`

### write

    public void write(java.lang.String s)
               throws java.io.IOException

  Write a string. This method cannot be inherited from the Writer class because it must suppress I/O exceptions.

  Clear the contents of the buffer. If the buffer has been already been flushed then the clear operation shall throw an IOException to signal the fact that some data has already been irrevocably written to the client response stream.

  Specified by:
    `clear` in class `javax.servlet.jsp.JspWriter`
  Throws:
    `java.io.IOException` - If an I/O error occurs

### clearBuffer

    public void clearBuffer()
                     throws java.io.IOException

  Clears the current contents of the buffer. Unlike clear(), this mehtod will not throw an IOException if the buffer has already been flushed. It merely clears the current content of the buffer and returns.

    `clearBuffer` in class `javax.servlet.jsp.JspWriter`
  Throws:
    `java.io.IOException` - If an I/O error occurs

### close

    public void close()
               throws java.io.IOException

  Close the stream, flushing it first. Once a stream has been closed, further write() or flush() invocations will cause an IOException to be thrown. Closing a previously-closed stream, however, has no effect.

  Specified by:
    `close` in class `javax.servlet.jsp.JspWriter`
  Throws:
    `java.io.IOException` - If an I/O error occurs

### getRemaining

    public int getRemaining()

  Specified by:
    `getRemaining` in class `javax.servlet.jsp.JspWriter`
  Returns:
    the number of bytes unused in the buffer

### getReader

    public java.io.Reader getReader()

  Return the value of this BodyJspWriter as a Reader. Note: this is after evaluation!! There are no scriptlets, etc in this stream.

  Specified by:
    `getReader` in class `javax.servlet.jsp.tagext.BodyContent`
  Returns:
    the value of this BodyJspWriter as a Reader

### getString

    public java.lang.String getString()

  Return the value of the BodyJspWriter as a String. Note: this is after evaluation!! There are no scriptlets, etc in this stream.

  Specified by:
    `getString` in class `javax.servlet.jsp.tagext.BodyContent`
  Returns:
    the value of the BodyJspWriter as a String

### writeOut

    public void writeOut(java.io.Writer out)
                  throws java.io.IOException

  Write the contents of this BodyJspWriter into a Writer. Subclasses are likely to do interesting things with the implementation so some things are extra efficient.

  Specified by:
    `writeOut` in class `javax.servlet.jsp.tagext.BodyContent`
  Parameters:
    `out` - The writer into which to place the contents of this body evaluation
    `java.io.IOException`

### main

    public static void main(java.lang.String[] args)
                     throws java.lang.Exception

    `java.lang.Exception`
