Class MethodDefinitionAttributes

java.lang.Object
  org.acegisecurity.intercept.method.AbstractMethodDefinitionSource
      org.acegisecurity.intercept.method.MethodDefinitionAttributes

All Implemented Interfaces:

MethodDefinitionSource, ObjectDefinitionSource

public class MethodDefinitionAttributes
extends AbstractMethodDefinitionSource

Stores a ConfigAttributeDefinition for each method signature defined by Commons Attributes.

This class will only detect those attributes which are defined for:

• The class-wide attributes defined for the intercepted class.
• The class-wide attributes defined for interfaces explicitly implemented by the intercepted class.
• The method-specific attributes defined for the intercepted method of the intercepted class.
• The method-specific attributes defined by any explicitly implemented interface if that interface contains a method signature matching that of the intercepted method.

Note that attributes defined against parent classes (either for their methods or interfaces) are not detected. The attributes must be defined against an explicit method or interface on the intercepted class.

Attributes detected that do not implement ConfigAttribute will be ignored.

setAttributes

public void setAttributes(Attributes attributes)

getConfigAttributeDefinitions

public Iterator getConfigAttributeDefinitions()

Description copied from interface: ObjectDefinitionSource

If available, 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.

Returns:

an iterator over all the ConfigAttributeDefinitions or null if unsupported

lookupAttributes

protected ConfigAttributeDefinition lookupAttributes(Method method)

Description copied from class: AbstractMethodDefinitionSource

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.

Specified by:

lookupAttributes in class AbstractMethodDefinitionSource

Parameters:

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

Returns:

the ConfigAttributeDefinition that applies to the specified Method
