checkError

public boolean checkError()
Flush the stream if it's not closed and check its error state. Errors are cumulative; once the stream encounters an error, this routine will return true on all successive calls.
Returns:
True if the print stream has encountered an error, either on the underlying output stream or during a format conversion.

clone

@Override
protected java.lang.Object clone()

close

@Override
public void close()

findStreamCharBufferTarget

protected java.io.Writer findStreamCharBufferTarget(boolean markUsed)

flush

@Override
public void flush()
Flush the stream.

leftShift

public GrailsPrintWriter leftShift(java.lang.Object value)
Provides Groovy << left shift operator, but intercepts call to make sure nulls are converted to "" strings
throws:
IOException
Parameters:
value - The value
Returns:
Returns this object

print

public void print(java.lang.Object obj)
Print an object. The string produced by the java.lang.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
See Also:
java.lang.Object#toString()

print

public void print(java.lang.String s)
Print a string. If the argument is null then the string "" 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
