How to create nested matcher

[Theodore David Williams]

I have a matcher that checks a list over a range for a certain value

    
package hamcrest;

import java.util.List;

import org.hamcrest.Description;
import org.hamcrest.Factory;
import org.junit.matchers.TypeSafeMatcher;


public class HasValueInRange extends TypeSafeMatcher<List<? extends Object>> {
	private final Object value;
	private final int from;
	private final int to;
	
	private HasValueInRange(Object value, int from, int to) {
		this.value = value;
		this.from = from;
		this.to = to;
	}
	
	public void describeTo(Description description) {
		// TODO Auto-generated method stub
	}

	@Override
	public boolean matchesSafely(List<? extends Object> values) {
		// Verify range is valid and in array
		if (from > to || to > values.size()) {
			return false;
		}
		
		for (int i = from; i < to; i++) {
			// If I am not equal I am done return false
			if (!values.get(i).equals(value)) {
				return false;
			}	
		}
		
		return true;
	}
	
	@Factory
	public static HasValueInRange hasValueInRange(Object value, int from, int to) {
		return new HasValueInRange(value, from, to);
	}

}

I am using it as follows:

    
List<String> test= Arrays.asList(new String[] {"Hello","Hello","Hello","Goodbye"});
assertThat(test, hasValueInRange("Hello", 0, 2);  // This will pass
assertThat(test, hasValueInRange("Hello", 0, 3); // fail last element is "Goodbye"

This works great, however I would really like to be more expressive and write the assert using nested Matchers, i.e.

    
List<String> test= Arrays.asList(new String[] {"Hello","Hello","Hello","Goodbye"});
assertThat(test, hasValue("Hello", inRange(0, 2));  // This will pass
assertThat(test, hasValue("Hello", inRange(0, 3)); // fail last element is "Goodbye"

So I want to pass an inRange matcher to the hasValue matcher. I am really struggling on how do implement this. I am just playing with hamcrest and trying to learn, thanks for any help!
