protected java.io.Writer findStreamCharBufferTarget(boolean markUsed)

flush

@Override
public void flush()
Flush the stream.

print

@Override
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

@Override
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
