Method Detail

close

public void close()

Description copied from class: Writer

This method closes the stream. Any internal or native resources associated with this stream are freed. Any subsequent attempt to access the stream might throw an exception.

This method in this class does nothing.

Specified by:

close in class Writer

write

public void write(char[] text,
                  int offset,
                  int len)

Description copied from class: Writer

This method writes len char from the specified array buf starting at index offset into the array.

Subclasses must provide an implementation of this abstract method.

Specified by:

write in class Writer

Parameters:

text - The array of char to write from

offset - The index into the array to start writing from

len - The number of char to write

setError

protected void setError()

This method can be called by subclasses to indicate that an error has occurred and should be reported by checkError.

checkError

public boolean checkError()

This method checks to see if an error has occurred on this stream. Note that once an error has occurred, this method will continue to report true forever for this stream. Before checking for an error condition, this method flushes the stream.

Returns:

true if an error has occurred, false otherwise

flush

public void flush()

This method flushes any buffered chars to the underlying stream and then flushes that stream as well.

Specified by:

flush in class Writer

print

public void print(String str)

This method prints a String to the stream. The actual value printed depends on the system default encoding.

Parameters:

str - The String to print.

print

public void print(char ch)

This method prints a char to the stream. The actual value printed is determined by the character encoding in use.

Parameters:

ch - The char value to be printed

print

public void print(char[] charArray)

This method prints an array of characters to the stream. The actual value printed depends on the system default encoding.

Parameters:

charArray - The array of characters to print.

print

public void print(boolean bool)

This methods prints a boolean value to the stream. true values are printed as "true" and false values are printed as "false".

Parameters:

bool - The boolean value to print

print

public void print(int inum)

This method prints an integer to the stream. The value printed is determined using the String.valueOf() method.

Parameters:

inum - The int value to be printed

print

public void print(long lnum)

This method prints a long to the stream. The value printed is determined using the String.valueOf() method.

Parameters:

lnum - The long value to be printed

print

public void print(float fnum)

This method prints a float to the stream. The value printed is determined using the String.valueOf() method.

Parameters:

fnum - The float value to be printed

print

public void print(double dnum)

This method prints a double to the stream. The value printed is determined using the String.valueOf() method.

Parameters:

dnum - The double value to be printed

print

public void print(Object obj)

This method prints an Object to the stream. The actual value printed is determined by calling the String.valueOf() method.

Parameters:

obj - The Object to print.

println

public void println()

This method prints a line separator sequence to the stream. The value printed is determined by the system property line.separator and is not necessarily the Unix '\n' newline character.

println

public void println(boolean bool)

This methods prints a boolean value to the stream. true values are printed as "true" and false values are printed as "false". This method prints a line termination sequence after printing the value.

Parameters:
