Write text to a character-output stream, buffering characters so as
to provide for the efficient writing of single characters, arrays,
and strings.
Provide support for discarding for the output that has been buffered.

Method Details
-
write
Write a single character.- Overrides:
write
in classWriter
- Throws:
IOException
-
write
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 classWriter
- Parameters:
cbuf
- A character arrayoff
- Offset from which to start reading characterslen
- Number of characters to write- Throws:
IOException
-
write

, and is not necessarily a single newline character ('\n'
).- Specified by:
println
in classjavax.servlet.jsp.JspWriter
- Throws:
IOException

.println()
- Specified by:
println

IOException
-
clear
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 classjavax.servlet.jsp.JspWriter

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.- Specified by:
clearBuffer

- Throws:
IOException
- If an I/O error occurs
-
close
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 interfaceAutoCloseable
- Specified by:
close
in interfaceCloseable
- Specified by:
close
in classjavax.servlet.jsp.JspWriter
- Throws:
IOException
- If an I/O error occurs
-
getRemaining
public int getRemaining()- Specified by:
getRemaining
in classjavax.servlet.jsp.JspWriter

- the number of bytes unused in the buffer
-
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 classjavax.servlet.jsp.tagext.BodyContent
- Returns:
- the value of this BodyJspWriter as a Reader
-
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 classjavax.servlet.jsp.tagext.BodyContent
- Returns:
- the value of the BodyJspWriter as a String
-
writeOut
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 classjavax.servlet.jsp.tagext.BodyContent
- Parameters:
out
