public interface SecurityMetadataSource
extends AopInfrastructureBean

Implemented by classes that store and can identify the ConfigAttributes that applies to a given secure object invocation.

Method Summary

Collection<ConfigAttribute>	getAllConfigAttributes() If available, returns all of the ConfigAttributes defined by the implementing class.
Collection<ConfigAttribute>	getAttributes(Object object) Accesses the ConfigAttributes that apply to a given secure object.
boolean	supports(Class<?> clazz) Indicates whether the SecurityMetadataSource implementation is able to provide ConfigAttributes for the indicated secure object type.

Method Detail

getAttributes

Collection<ConfigAttribute> getAttributes(Object object)
                                          throws IllegalArgumentException

Accesses the ConfigAttributes that apply to a given secure object.

Parameters:

object - the object being secured

Returns:

the attributes that apply to the passed in secured object. Should return an empty collection 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
