Method Detail

resolvers

public static Iterable<Resolver> resolvers(Object object)

Provides an iterable object over the resolvers that are appropriate for a particular object. Resolvers are provided ordered from most specific to class/interface to least. Resolvers are provided through an iterator interface to avoid the overhead of determining all resolvers in advance.

Parameters:

object - the object for which a set of resolvers is being sought.

Returns:

an object that returns an iterator over the set of resolvers for the object.

get

public static Object get(Object object,
                         Object element)

Attempts to resolve an element of an object.

Parameters:

object - the object in which to resolve the specified element.

element - the element to resolve within the specified object.

Returns:

the value of the resolved element, or UNRESOLVED if it cannot be resolved.

See Also:

Resolver.get(Object, Object)

put

public static Object put(Object object,
                         Object element,
                         Object value)

Attempts to set the value of an element of an object.

Parameters:

object - the object in which to resolve the specified element.

element - the element within the specified object whose value is to be set.

value - the value to set the element to.

Returns:

the previous value of the element, null if no previous value, or UNRESOLVED if it cannot be resolved.
