Method Summary

Modifier and Type	Method and Description
static boolean	checkConfigurationClassCandidate(BeanDefinition beanDef, MetadataReaderFactory metadataReaderFactory) Check whether the given bean definition is a candidate for a configuration class (or a nested component class declared within a configuration/component class, to be auto-registered as well), and mark it accordingly.
static boolean	isConfigurationCandidate(AnnotationMetadata metadata) Check the given metadata for a configuration class candidate (or nested component class declared within a configuration/component class).
static boolean	isFullConfigurationCandidate(AnnotationMetadata metadata) Check the given metadata for a full configuration class candidate (i.e.
static boolean	isFullConfigurationClass(BeanDefinition beanDef) Determine whether the given bean definition indicates a full @Configuration class, through checking checkConfigurationClassCandidate(org.springframework.beans.factory.config.BeanDefinition, org.springframework.core.type.classreading.MetadataReaderFactory)'s metadata marker.
static boolean	isLiteConfigurationCandidate(AnnotationMetadata metadata) Check the given metadata for a lite configuration class candidate (e.g.
static boolean	isLiteConfigurationClass(BeanDefinition beanDef) Determine whether the given bean definition indicates a lite @Configuration class, through checking checkConfigurationClassCandidate(org.springframework.beans.factory.config.BeanDefinition, org.springframework.core.type.classreading.MetadataReaderFactory)'s metadata marker.

Method Detail

checkConfigurationClassCandidate

public static boolean checkConfigurationClassCandidate(BeanDefinition beanDef,
                                                       MetadataReaderFactory metadataReaderFactory)

Check whether the given bean definition is a candidate for a configuration class (or a nested component class declared within a configuration/component class, to be auto-registered as well), and mark it accordingly.

Parameters:

beanDef - the bean definition to check

metadataReaderFactory - the current factory in use by the caller

Returns:

whether the candidate qualifies as (any kind of) configuration class

isConfigurationCandidate

public static boolean isConfigurationCandidate(AnnotationMetadata metadata)

Check the given metadata for a configuration class candidate (or nested component class declared within a configuration/component class).

Parameters:

metadata - the metadata of the annotated class

Returns:

true if the given class is to be registered as a reflection-detected bean definition; false otherwise

isFullConfigurationCandidate

public static boolean isFullConfigurationCandidate(AnnotationMetadata metadata)

Check the given metadata for a full configuration class candidate (i.e. a class annotated with @Configuration).

Parameters:

metadata - the metadata of the annotated class

Returns:

true if the given class is to be processed as a full configuration class, including cross-method call interception

isLiteConfigurationCandidate

public static boolean isLiteConfigurationCandidate(AnnotationMetadata metadata)

Check the given metadata for a lite configuration class candidate (e.g. a class annotated with @Component or just having @Import declarations or @Bean methods).

Parameters:

metadata - the metadata of the annotated class

Returns:

true if the given class is to be processed as a lite configuration class, just registering it and scanning it for @Bean methods

isFullConfigurationClass

public static boolean isFullConfigurationClass(BeanDefinition beanDef)

Determine whether the given bean definition indicates a full @Configuration class, through checking checkConfigurationClassCandidate(org.springframework.beans.factory.config.BeanDefinition, org.springframework.core.type.classreading.MetadataReaderFactory)'s metadata marker.

isLiteConfigurationClass

public static boolean isLiteConfigurationClass(BeanDefinition beanDef)

Determine whether the given bean definition indicates a lite @Configuration class, through checking checkConfigurationClassCandidate(org.springframework.beans.factory.config.BeanDefinition, org.springframework.core.type.classreading.MetadataReaderFactory)'s metadata marker.
