/**
 * Construct a new pattern matching filter.
 *
 * @param pattern
 *            text of the pattern. Callers may want to surround their
 *            pattern with ".*" on either end to allow matching in the
 *            middle of the string.
 * @param innerString
 *            should .* be wrapped around the pattern of ^ and $ are
 *            missing? Most users will want this set.
 * @param rawEncoding
 *            should {@link #forceToRaw(String)} be applied to the pattern
 *            before compiling it?
 * @param flags
 *            flags from {@link Pattern} to control how matching performs.
