Method Detail

write

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

Write a single character.

Throws:

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 DiscardableBufferedWriters will not copy data unnecessarily.

Parameters:

cbuf - A character array

off - Offset from which to start reading characters

len - Number of characters to write

Throws:

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.

Throws:

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.

Parameters:

s - String to be written

off - Offset from which to start reading characters

len - Number of characters to be written

Throws:

java.io.IOException

write

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

Throws:

java.io.IOException

newLine

public void newLine()
             throws java.io.IOException

Write a line separator. The line separator string is defined by the system property line.separator, and is not necessarily a single newline ('\n') character.

Throws:

java.io.IOException - If an I/O error occurs

print

public void print(boolean b)
           throws java.io.IOException

Parameters:

f - The float to be printed

Throws:

java.io.IOException

print

public void print(double d)
           throws java.io.IOException

Print a double-precision floating-point number. The string produced by String.valueOf(double) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Parameters:

d - The double to be printed

Throws:

java.io.IOException

print

public void print(char[] s)
           throws java.io.IOException

Print an array of characters. The characters are converted into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Parameters:

s - The array of chars to be printed

Throws:

java.lang.NullPointerException - If s is null

java.io.IOException

print

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

Print a string. If the argument is null then the string "null" is printed. Otherwise, the string's characters are converted into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Parameters:

s - The String to be printed

Throws:

java.io.IOException

print

public void print(java.lang.Object obj)
           throws java.io.IOException

Print an object. The string produced by the String.valueOf(Object) method is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Parameters:

obj - The Object to be printed

Throws:

java.io.IOException

println

public void println()
             throws java.io.IOException

Terminate the current line by writing the line separator string. The line separator string is defined by the system property line.separator, and is not necessarily a single newline character ('\n').

Throws:

java.io.IOException

Throws:

java.io.IOException

clear

public void clear()
           throws java.io.IOException

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.

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.

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.

Throws:

java.io.IOException - If an I/O error occurs

getRemaining

public int getRemaining()

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.

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.

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.

Parameters:

out - The writer into which to place the contents of this body evaluation

Throws:

java.io.IOException
