NSPrintWriter
public NSPrintWriter(OutputStream out)(Code)
Create a new PrintWriter, without automatic line flushing, from an existing OutputStream. This convenience constructor creates the necessary intermediate OutputStreamWriter, which will convert characters into bytes using the default character encoding.
Parameters:

See Also:   java.io.OutputStreamWriter.OutputStreamWriter(java.io.OutputStream)




Method Detail
checkError
public boolean checkError()(Code)
Flush the stream and check its error state. Errors are cumulative; once the stream encounters an error, this routine will return true on all successive calls. True if the print stream has encountered an error, either on theunderlying output stream or during a format conversion.



close
public void close()(Code)
Close the stream.



flush
public void flush()(Code)
Flush the stream.



print
public void print(boolean b)(Code)
Print a boolean value. The string produced by java.lang.String.valueOf(boolean) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the NSPrintWriter.write(int) method.
Parameters:
  b - The boolean to be printed



print
public void print(char c)(Code)
Print a character. The character is translated into one or more bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the NSPrintWriter.write(int) method.
Parameters:
  c - The char to be printed



print
public void print(int i)(Code)
Print an integer. The string produced by java.lang.String.valueOf(int) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the NSPrintWriter.write(int) method.
Parameters:
  i - The int to be printed
See Also:   java.lang.Integer.toString(int)



print
public void print(long l)(Code)
Print a long integer. The string produced by java.lang.String.valueOf(long) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the NSPrintWriter.write(int) method.
Parameters:
  l - The long to be printed
See Also:   java.lang.Long.toString(long)



print
public void print(float f)(Code)
Print a floating-point number. The string produced by java.lang.String.valueOf(float) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the NSPrintWriter.write(int) method.
Parameters:
  f - The float to be printed
See Also:   java.lang.Float.toString(float)



print
public void print(double d)(Code)
Print a double-precision floating-point number. The string produced by java.lang.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 NSPrintWriter.write(int) method.
Parameters:
  d - The double to be printed
See Also:   java.lang.Double.toString(double)



print
public void print(char s)(Code)
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 NSPrintWriter.write(int) method.
Parameters:
  s - The array of chars to be printed
throws:
  NullPointerException - If s is null



print
public void print(String s)(Code)
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 NSPrintWriter.write(int) method.

Parameters:
  x - the float value to be printed



println
public void println(double x)(Code)
Print a double-precision floating-point number and then terminate the line. This method behaves as though it invokes NSPrintWriter.print(double) and then NSPrintWriter.println() .

  x - the double value to be printed



println
public void println(char x)(Code)
Print an array of characters and then terminate the line. This method behaves as though it invokes NSPrintWriter.print(char[]) and then NSPrintWriter.println() .
Parameters:
  x - the array of char values to be printed



println
public void println(String x)(Code)
Print a String and then terminate the line. This method behaves as though it invokes NSPrintWriter.print(String) and then NSPrintWriter.println() .
Parameters:
  x - the String value to be printed



println
public void println(Object x)(Code)
Print an Object and then terminate the line. This method behaves as though it invokes NSPrintWriter.print(Object) and then NSPrintWriter.println() .
