I'm wondering how can I solve this Compilation Failure I got in JDK 1.7, the code works perfectly with JDK 1.6.
Error I got: MatchStrings.java:[71,36] error: name clash: with(ElementMatcher) in MatchStrings and with(ElementMatcher) in MatchElements have the same erasure, yet neither hides the other
My classes in questions:
public class MatchStrings extends MatchElements
{
public static class StringMatcherImpl extends ElementMatcherImpl<String>
{
public StringMatcherImpl(ElementMatcher<String> matcher)
{
super(matcher);
}
}
public static class PrefixMatcher implements ElementMatcher<String>
{
private final String _prefix;
public PrefixMatcher(String prefix)
{
_prefix = prefix;
}
@Override
public boolean matches(String str)
{
return str.startsWith(_prefix);
}
}
public static class SuffixMatcher implements ElementMatcher<String>
{
private final String _suffix;
public SuffixMatcher(String suffix)
{
_suffix = suffix;
}
@Override
public boolean matches(String str)
{
return str.endsWith(_suffix);
}
}
public static StringMatcherImpl with(ElementMatcher<String> matcher)
{
return new StringMatcherImpl(matcher);
}
public static StringMatcherImpl startingWith(String prefix)
{
return with(new PrefixMatcher(prefix));
}
public static StringMatcherImpl endingWith(String prefix)
{
return with(new SuffixMatcher(prefix));
}
}
public class MatchElements
{
public static class ElementMatcherImpl<E> implements ElementMatcher<E>
{
private ElementMatcher<E> _matcher;
ElementMatcherImpl(ElementMatcher<E> matcher)
{
_matcher = matcher;
}
@Override
public boolean matches(E e)
{
return _matcher.matches(e);
}
public ElementMatcherImpl<E> and(ElementMatcher<E> m)
{
_matcher = new ElementMatcherAndChain<E>(_matcher, m);
return this;
}
public ElementMatcherImpl<E> or(ElementMatcher<E> m)
{
_matcher = new ElementMatcherOrChain<E>(_matcher, m);
return this;
}
@Override
public String toString()
{
return _matcher.toString();
}
}
public static <E> ElementMatcherImpl<E> with(ElementMatcher<E> matcher)
{
return new ElementMatcherImpl<E>(matcher);
}
public static <E> ElementMatcherImpl<E> not(ElementMatcher<E> matcher)
{
return with(new ElementMatcherNegator<E>(matcher));
}
}
public static StringMatcherImpl with(ElementMatcher<String> matcher)
in MatchStrings
and
public static <E> ElementMatcherImpl<E> with(ElementMatcher<E> matcher)
in MatchElements
type-erase to
with(ElementMatcher matcher)
which is no longer valid, starting with Java 7, as @Tom said.
If possible, rename with(ElementMatcher<String> matcher)
to something more specific, like withStringMatcher(ElementMatcher<String> matcher)
