Method Detail

getAttribute

public EvaluationResult getAttribute(URI type,
                                     URI id,
                                     String issuer,
                                     URI category)

Description copied from interface: EvaluationCtx

Returns available subject attribute value(s).

Parameters:

type - the type of the attribute value(s) to find

id - the id of the attribute value(s) to find

issuer - the issuer of the attribute value(s) to find or null

category - the category the attribute value(s) must be in

Returns:

a result containing a bag either empty because no values were found or containing at least one value, or status associated with an Indeterminate result

getAttribute

public EvaluationResult getAttribute(String path,
                                     URI type,
                                     URI category,
                                     URI contextSelector,
                                     String xpathVersion)

Description copied from class: BasicEvaluationCtx

Returns the attribute value(s) retrieved using the given XPath expression.

Specified by:

getAttribute in interface EvaluationCtx

Overrides:

getAttribute in class BasicEvaluationCtx

Parameters:

path - the XPath expression to search

type - the type of the attribute value(s) to find

category - the category the attribute value(s) must be in

contextSelector - the selector to find the context to apply XPath expression if this is null, applied for default content

xpathVersion - the version of XPath to use

Returns:

a result containing a bag either empty because no values were found or containing at least one value, or status associated with an Indeterminate result

getXacmlVersion

public int getXacmlVersion()

Description copied from interface: EvaluationCtx

Returns XACML version of the context

Returns:

version

getMultipleEvaluationCtx

public MultipleCtxResult getMultipleEvaluationCtx()

Description copied from interface: EvaluationCtx

Returns multiple context results. if, request is combination of multiple requests

Returns:

MultipleCtxResult

setResourceId

public void setResourceId(AttributeValue resourceId,
                          Set<Attributes> attributesSet)

Changes the value of the resource-id attribute in this context. This is useful when you have multiple resources (ie, a scope other than IMMEDIATE), and you need to keep changing only the resource-id to evaluate the different effective requests.

Parameters:

resourceId - resourceId the new resource-id value

attributesSet - a Set of Attributes

isMultipleAttributes

public boolean isMultipleAttributes()

getRequestCtx

public AbstractRequestCtx getRequestCtx()

Description copied from interface: EvaluationCtx

Returns XACML request

Specified by:

getRequestCtx in interface EvaluationCtx

Specified by:

getRequestCtx in class BasicEvaluationCtx

Returns:

AbstractRequestCtx

getPolicyReferences

public Set<PolicyReference> getPolicyReferences()

Returns:

setPolicyReferences

public void setPolicyReferences(Set<PolicyReference> policyReferences)

Parameters:

policyReferences -

getAttributes

public List<Attributes> getAttributes(String category)

Parameters:

category -

Returns:

getMultipleContentSelectors

public Set<Attributes> getMultipleContentSelectors()

getMapAttributes

public Map<String,List<Attributes>> getMapAttributes()

getAttributesSet

public Set<Attributes> getAttributesSet()

getResourceId

public Attribute getResourceId()

getResourceScope

public int getResourceScope()
