Method Detail

getAttributes

Collection<ConfigAttribute> getAttributes(Object object)
                                          throws IllegalArgumentException
Accesses the ConfigAttributes that apply to a given secure object.

Returns null if no attributes apply.

Parameters:
object - the object being secured
Returns:
the attributes that apply to the passed in secured object or null if there are no applicable attributes.
Throws:
IllegalArgumentException - if the passed object is not of a type supported by the SecurityMetadataSource implementation

getAllConfigAttributes

Collection<ConfigAttribute> getAllConfigAttributes()
If available, returns all of the ConfigAttributes defined by the implementing class.

This is used by the AbstractSecurityInterceptor to perform startup time validation of each ConfigAttribute configured against it.

Returns:
the ConfigAttributes or null if unsupported

supports

boolean supports(Class<?> clazz)
Indicates whether the SecurityMetadataSource implementation is able to provide ConfigAttributes for the indicated secure object type.

Parameters:
clazz - the class that is being queried
Returns:
true if the implementation can process the indicated class
