Constructor Detail

UncheckedPrintWriter

public UncheckedPrintWriter(Writer out)

UncheckedPrintWriter

public UncheckedPrintWriter(Writer out,
                            boolean autoFlush)
Create a new PrintWriter.

Parameters:
out - A character-output stream
autoFlush - A boolean; if true, the println() methods will flush the output buffer

UncheckedPrintWriter

public UncheckedPrintWriter(OutputStream out)
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:
out - An output stream
See Also:
OutputStreamWriter.OutputStreamWriter(java.io.OutputStream)

UncheckedPrintWriter

public UncheckedPrintWriter(OutputStream out,
                            boolean autoFlush)
Create a new PrintWriter from an existing OutputStream. This convenience constructor creates the necessary intermediate OutputStreamWriter, which will convert characters into bytes using the default character encoding.

Parameters:
out - An output stream
autoFlush - A boolean; if true, the println() methods will flush the output buffer
See Also:
OutputStreamWriter.OutputStreamWriter(java.io.OutputStream)
Method Detail

isUncheckedPrintWriter

public boolean isUncheckedPrintWriter()
Are unchecked exceptions thrown.

Returns:
True if RuntimeIOExceptions are thrown

setUncheckedPrintWriter

public void setUncheckedPrintWriter(boolean uncheckedPrintWriter)
Set if unchecked exceptions are thrown

Parameters:
uncheckedPrintWriter - True if RuntimeIOExceptions are to be thrown

flush

public void flush()
Flush the stream.

Specified by:
flush in interface Flushable
Overrides:
flush in class PrintWriter

close

public void close()
Close the stream.

Specified by:
close in interface Closeable
Overrides:
close in class PrintWriter

write

public void write(int c)
Write a single character.

Overrides:
write in class PrintWriter
Parameters:
c - int specifying a character to be written.

write

public void write(char[] buf,
                  int off,
                  int len)
Write a portion of an array of characters.

Overrides:
write in class PrintWriter
Parameters:
buf - Array of characters
off - Offset from which to start writing characters
len - Number of characters to write

write

public void write(char[] buf)
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 PrintWriter
Parameters:
buf - Array of characters to be written

write

public void write(String s,
                  int off,
                  int len)
Write a portion of a string.

Overrides:
write in class PrintWriter
Parameters:
s - A String
off - Offset from which to start writing characters
len - Number of characters to write

write

public void write(String s)
Write a string. This method cannot be inherited from the Writer class because it must suppress I/O exceptions.

Overrides:
write in class PrintWriter
Parameters:
s - String to be written

print

public void print(boolean b)
Print a boolean value. The string produced by 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 write(int) method.

Overrides:
print in class PrintWriter
Parameters:
b - The boolean to be printed

print

public void print(char c)
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 write(int) method.

Overrides:
print in class PrintWriter
Parameters:
c - The char to be printed

print

public void print(int i)
Print an integer. The string produced by 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 write(int) method.

Overrides:
print in class PrintWriter
Parameters:
i - The int to be printed
See Also:
Integer.toString(int)

print

public void print(long l)
Print a long integer. The string produced by 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 write(int) method.

Overrides:
print in class PrintWriter
Parameters:
l - The long to be printed
See Also:
Long.toString(long)

print

public void print(float f)
Print a floating-point number. The string produced by 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 write(int) method.

Overrides:

Overrides:
print in class PrintWriter
Parameters:
d - The double to be printed
See Also:
Double.toString(double)

print

public void print(char[] s)

Overrides:
print in class PrintWriter
Parameters:
s - The array of chars to be printed
Throws:
NullPointerException - If s is null

print

public void print(String s)
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.
