resolveScopeMetadata

public ScopeMetadata resolveScopeMetadata(BeanDefinition definition)

Description copied from interface: ScopeMetadataResolver

Resolve the ScopeMetadata appropriate to the supplied bean definition.

Implementations can of course use any strategy they like to determine the scope metadata, but some implementations that spring immediately to mind might be to use source level annotations present on the class of the supplied definition, or to use metadata present in the AttributeAccessor.attributeNames() of the supplied definition.

Specified by:

resolveScopeMetadata in interface ScopeMetadataResolver

Parameters:

definition - the target bean definition

Returns:

the relevant scope metadata; never null
