lookup

public IResource lookup(Class resourceInterface)

Lookup a matching resource Interface. Returns the first resource found that implements the specified resourceInterface. Subsequent calls may return another resourceInterface instance.

Specified by:

lookup in interface ICompositeResource

Parameters:

resourceInterface - the desired type of resource

Returns:

a matching resource or null if no matches

lookupAll

public IResource[] lookupAll(Class resourceInterface)

Lookup all the matching resource Interfaces. Returns all the resources found that implement the specified resourceInterface.

Specified by:

lookupAll in interface ICompositeResource

Parameters:

resourceInterface - the desired type of resource

Returns:

an array of matching resources or an empty array if no matches

lookup

public IResource lookup(Class resourceInterface,
                        String tag)
