The interface ResourceManipulator
provides
methods to determine the hierarchy of resource names.
Also it provides an interface to determine the service
type to which it be used. Service developers could
provide an implementation of this interface that will
determine its hierarchy during policy evaluation and
also its display in the GUI. A class that implements
this interface must have a empty constructor.

Method Detail |
public java.util.Set getServiceTypeNames()
public void initialize(java.util.Map configParams)
configParams
- configuration parameters as a map.
The keys of the map are the configuration parameters.
Each key is corresponding to one String
value
which specifies the configuration parameter value.public ResourceMatch compare(java.lang.String origRes, java.lang.String compRes, boolean wildcardCompare)
origRes
- name of the resource which will be comparedcompRes
- name of the resource which will be compared withwildcardCompare
- flag for wildcard comparisonResourceMatch
that
specifies if the resources are exact match, or
otherwise.
ResourceMatch.NO_MATCH
means two resources do not match
ResourceMatch.EXACT_MATCH
means two resources match
ResourceMatch.SUB_RESOURCE_MATCH
means
compRes
is the sub resource of the origRes
ResourceMatch.SUPER_RESOURCE_MATCH
means
compRes
is the super resource of the
origRes
ResourceMatch.WILDCARD_MATCH
means two resources match
with respect to the wildcard
public java.lang.String append(java.lang.String superResource, java.lang.String subResource)
superResource
- name of the super-resource to be appended to.subResource
- name of the sub-resource to be appended.public java.lang.String getSubResource(java.lang.String res, java.lang.String superRes)
res
- name of the original resource consisting of
the second parameter superRes
and the returned valuesuperRes
- name of the super-resource which the first
parameter begins with.public java.lang.String canonicalize(java.lang.String res) throws PolicyException
res
- the resource string to be canonicalizedPolicyException
- if resource string is invalidpublic java.lang.String[] split(java.lang.String res)
