public boolean isValidInput() {
		return true;
	}
Returns true if this byte matcher has valid (but possibly incomplete) input text. For 
example, when entering decimal values, the input could be just "-" as the user starts
to enter a negative number. In this case the input is valid, but the {@link #isValidSearch()}
would return false.
