Examples of java.nio.CharBuffer.array()

java.nio.CharBuffer.array()
Returns the char array which this buffer is based on, if there's one. @return The char array which this buffer is based on @exception ReadOnlyBufferException If this buffer is based on an array, but it is readonly @exception UnsupportedOperationException If this buffer is not based on an array
