Modifier and Type	Method and Description
static BeanDefinitionBuilder	createBeanDefinitionBuilderIfNoBeanDefinitionOfTypeExists(ListableBeanFactory factory, Class<?> requiredType, Class<?> instantiableType, BeanDefinitionBuilderArgument... constructorArgs) Returns a BeanDefinitionBuilder iff no BeanDefinition of the required type is found in the given ListableBeanFactory, otherwise returns null, indicating that at least one existed.
static BeanDefinitionHolder[]	getBeanDefinitionsOfType(BeanDefinitionRegistry registry, ListableBeanFactory factory, Class<?> type, boolean includeNonSingletons, boolean allowEagerInit) Returns all BeanDefinitionHolders with the given type.
static BeanDefinitionHolder	getSingleBeanDefinitionOfType(BeanDefinitionRegistry registry, ListableBeanFactory factory, Class<?> type, boolean includeNonSingletons, boolean allowEagerInit, boolean required) Returns the single BeanDefinitionHolder with the given type, or null of none were found and required was false, otherwise throws IllegalArgumentException.

createBeanDefinitionBuilderIfNoBeanDefinitionOfTypeExists

public static BeanDefinitionBuilder createBeanDefinitionBuilderIfNoBeanDefinitionOfTypeExists(ListableBeanFactory factory,
                                                                              Class<?> requiredType,
                                                                              Class<?> instantiableType,
                                                                              BeanDefinitionBuilderArgument... constructorArgs)

Returns a BeanDefinitionBuilder iff no BeanDefinition of the required type is found in the given ListableBeanFactory, otherwise returns null, indicating that at least one existed.

Parameters:

factory - The ListableBeanFactory in which to look for the BeanDefinition, including ancestors.

requiredType - The BeanDefinition's required type.

instantiableType - The instantiable type for the BeanDefinitionBuilder.

constructorArgs - Any BeanDefinitionBuilderArguments required by the instantiableType's constructor.

Returns:

A BeanDefinitionBuilder iff no BeanDefinition of the required type is found, otherwise null.

getSingleBeanDefinitionOfType

public static BeanDefinitionHolder getSingleBeanDefinitionOfType(BeanDefinitionRegistry registry,
                                                 ListableBeanFactory factory,
                                                 Class<?> type,
                                                 boolean includeNonSingletons,
                                                 boolean allowEagerInit,
                                                 boolean required)

Returns the single BeanDefinitionHolder with the given type, or null of none were found and required was false, otherwise throws IllegalArgumentException.

Parameters:

registry - The BeanDefinitionRegistry, often the very same instance as the factor parameter.

factory - The ListableBeanFactory, often the very same instance as the registry parameter.

type - The required BeanDefinition's type.

includeNonSingletons - Whether to include beans with scope other than singleton

allowEagerInit - Whether to allow eager initialization of beans.

required - Whether to allow the return of null if none were found.

Returns:

The BeanDefinitionHolder or null if none found, depending on the value of required.

Throws:

IllegalArgumentException - If multiple were found.

getBeanDefinitionsOfType

public static BeanDefinitionHolder[] getBeanDefinitionsOfType(BeanDefinitionRegistry registry,
                                              ListableBeanFactory factory,
                                              Class<?> type,
                                              boolean includeNonSingletons,
                                              boolean allowEagerInit)

Returns all BeanDefinitionHolders with the given type.

Parameters:

registry - The BeanDefinitionRegistry, often the very same instance as the factor parameter.

factory - The ListableBeanFactory, often the very same instance as the registry parameter.

type - The required BeanDefinition's type.

includeNonSingletons - Whether to include beans with scope other than singleton

allowEagerInit - Whether to allow eager initialization of beans.

required - Whether to allow the return of null if none were found.

Returns:

The BeanDefinitionHolders -- never returns null.
