Methods Summary
public booleanequals(java.lang.Object obj)
Equality comparison.

	if (!(obj instanceof StringTerm))
	    return false;
	StringTerm st = (StringTerm)obj;
	if (ignoreCase)
	    return st.pattern.equalsIgnoreCase(this.pattern) &&
		    st.ignoreCase == this.ignoreCase;
	else
	    return st.pattern.equals(this.pattern) &&
		    st.ignoreCase == this.ignoreCase;
public booleangetIgnoreCase()
Return true if we should ignore case when matching.

	return ignoreCase;
public java.lang.StringgetPattern()
Return the string to match with.

	return pattern;
public inthashCode()
Compute a hashCode for this object.

	return ignoreCase ? pattern.hashCode() : ~pattern.hashCode();
protected booleanmatch(java.lang.String s)

	int len = s.length() - pattern.length();
	for (int i=0; i <= len; i++) {
	    if (s.regionMatches(ignoreCase, i, 
				pattern, 0, pattern.length()))
		return true;
	}
	return false;
