Method Detail

getAttributes

public ConfigAttributeDefinition getAttributes(Object object)
                                        throws IllegalArgumentException

Description copied from interface: ObjectDefinitionSource

Accesses the ConfigAttributeDefinition that applies to a given secure object.

Returns null if no ConfigAttribiteDefinition applies.

Specified by:

getAttributes in interface ObjectDefinitionSource

Parameters:

object - the object being secured

Returns:

the ConfigAttributeDefinition that applies to the passed object

Throws:

IllegalArgumentException - if the passed object is not of a type supported by the ObjectDefinitionSource implementation

supports

public boolean supports(Class clazz)

Description copied from interface: ObjectDefinitionSource

Indicates whether the ObjectDefinitionSource implementation is able to provide ConfigAttributeDefinitions for the indicated secure object type.

Specified by:

supports in interface ObjectDefinitionSource

Parameters:

clazz - the class that is being queried

Returns:

true if the implementation can process the indicated class

lookupAttributes

protected abstract ConfigAttributeDefinition lookupAttributes(Method method)

Performs the actual lookup of the relevant ConfigAttributeDefinition for the specified Method which is subject of the method invocation.

Provided so subclasses need only to provide one basic method to properly interface with the MethodDefinitionSource.

Returns null if there are no matching attributes for the method.

Parameters:

method - the method being invoked for which configuration attributes should be looked up

Returns:

the ConfigAttributeDefinition that applies to the specified Method
