Method Summary

Modifier and Type	Method and Description
Class<T>	getBeanType() Returns the bean type.
default Set<Class<?>>	getExposedTypes() Returns a potentially limited subset of bean types exposed by this bean.
default String	getName()
default boolean	isCandidateBean(Argument<?> beanType) Return whether this bean type is a candidate for dependency injection for the passed type.
default boolean	isContainerType() Checks whether the bean type is a container type.
default boolean	isPrimary()
default boolean	requiresMethodProcessing() By default, when the BeanContext is started, the BeanDefinition.getExecutableMethods() are not processed by registered ExecutableMethodProcessor instances unless this method returns true.

Method Detail

isPrimary

default boolean isPrimary()

Returns:

Whether the bean definition is the Primary

getBeanType

Class<T> getBeanType()

Returns the bean type.

Returns:

The underlying bean type

isContainerType

default boolean isContainerType()

Checks whether the bean type is a container type.

Returns:

Whether the type is a container type like Iterable.

Since:

3.0.0

getExposedTypes

@NonNull
default Set<Class<?>> getExposedTypes()

Returns a potentially limited subset of bean types exposed by this bean. The types to be exposed can be defined by the Type annotation.

Returns:

The exposed types

Since:

3.0.0

isCandidateBean

default boolean isCandidateBean(@Nullable
                                Argument<?> beanType)

Return whether this bean type is a candidate for dependency injection for the passed type.

Parameters:

beanType - The bean type

Returns:

True if it is

Since:

3.0.0

getName

default String getName()

Returns:

The class name

requiresMethodProcessing

default boolean requiresMethodProcessing()

By default, when the BeanContext is started, the BeanDefinition.getExecutableMethods() are not processed by registered ExecutableMethodProcessor instances unless this method returns true.

Returns:

Whether the bean definition requires method processing
