public BeanProviderDefinition()

Method Details

isEnabled

public boolean isEnabled(BeanContext context,
 BeanResolutionContext resolutionContext)

Description copied from interface: BeanContextConditional

Return whether this component is enabled for the given context.

Specified by:

isEnabled in interface BeanContextConditional

Overrides:

isEnabled in class AbstractProviderDefinition<BeanProvider<Object>>

Parameters:

context - The context

resolutionContext - The bean resolution context

Returns:

True if it is

getBeanType

public Class<BeanProvider<Object>> getBeanType()

Description copied from interface: BeanType

Returns the bean type.

Returns:

The produced bean type

isPresent

public boolean isPresent()

Specified by:

isPresent in interface BeanDefinitionReference<BeanProvider<Object>>

Overrides:

isPresent in class AbstractProviderDefinition<BeanProvider<Object>>

Returns:

Is the underlying bean type present on the classpath

buildProvider

protected BeanProvider<Object> buildProvider(@NonNull
 @NonNull BeanResolutionContext resolutionContext,
 @NonNull
 @NonNull BeanContext context,
 @NonNull
 @NonNull Argument<Object> argument,
 @Nullable
 @Nullable Qualifier<Object> qualifier,
 boolean singleton)

Description copied from class: AbstractProviderDefinition

Builds a provider implementation.

Specified by:

Parameters:

resolutionContext - The resolution context

context - The context

argument - The argument

qualifier - The qualifier

singleton - Whether the bean is a singleton
