                        throws Exception

Specified by:

afterPropertiesSet in interface InitializingBean

Throws:

Exception

getAttributes

public ConfigAttributeDefinition getAttributes(Method method,
                                               Class targetClass)

Specified by:

getAttributes in interface MethodDefinitionSource

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

getConfigAttributeDefinitions

public Collection getConfigAttributeDefinitions()

Description copied from interface: ObjectDefinitionSource

If available, returns all of the ConfigAttributeDefinitions defined by the implementing class.

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

Specified by:

getConfigAttributeDefinitions in interface ObjectDefinitionSource

Returns:

the ConfigAttributeDefinitions or null if unsupported

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

setMethodDefinitionSources

public void setMethodDefinitionSources(List methodDefinitionSources)
