Usage

From source file:org.grouplens.grapht.BindingImpl.java

@Override
public void to(@Nullable T instance) {
    if (instance == null) {
        toNull();/*from   w  ww . j  a va2 s .  co  m*/
        return;
    } else if (!(instance instanceof Number) && !ClassUtils.isPrimitiveWrapper(instance.getClass())
            && !sourceType.isInstance(instance)) {
        String msg = String.format("%s is not an instance of %s", instance, sourceType);
        throw new InvalidBindingException(sourceType, msg);
    }

    // Apply some type coercing if we're dealing with primitive types
    Object coerced = coerce(instance);
    Satisfaction s = Satisfactions.instance(coerced);
    BindRuleBuilder brb = startRule().setSatisfaction(s);
    generateBindings(brb, coerced.getClass());
