ResourceProvider
null
if
the resource provider cannot find it. The path should have one of the
ResourceProvider.ROOTS
strings as its prefix.
This method is called to resolve a resource for the given request. The properties of the request, such as request parameters, may be use to parametrize the resource resolution. An example of such parametrization is support for a JSR-311 style resource provider to support the parametrized URL patterns.

ResourceProvider
Iterator
of Resource
objects loaded
from the children of the given Resource
. The returned
Resource
instances are attached to the same
ResourceResolver
as the given parent
resource.
This method may be called for resource providers whose root path list contains a path such that the resource path is a prefix of the list entry. This allows for the enumeration of deeply nested provided resources for which no actual parent hierarchy exists.
The returned iterator may in turn contain resources which do not actually
exist but are required to traverse the resource tree. Such resources
SHOULD be SyntheticResource
objects whose resource type MUST be
set to ResourceProvider.RESOURCE_TYPE_SYNTHETIC
.
