Constructor Detail

PetiteBeans

protected PetiteBeans(PetiteConfig petiteConfig)

Method Detail

getParamManager

public ParamManager getParamManager()

Returns parameter manager.

getConfig

public PetiteConfig getConfig()

Returns Petite configuration. All changes on config should be done before beans registration process starts.

resolveScope

protected Scope resolveScope(java.lang.Class<? extends Scope> scopeType)

Resolves scope from scope type.

registerScope

public void registerScope(java.lang.Class<? extends Scope> scopeType,
                          Scope scope)

Registers new scope. It is not necessary to manually register scopes, since they become registered on first scope resolving. However, it is possible to pre-register some scopes, or to replace one scope type with another. This may be important for testing purposes when using container-depended scopes.

lookupBeanDefinition

public BeanDefinition lookupBeanDefinition(java.lang.String name)

Lookups for bean definition. Returns null if bean name doesn't exist.

lookupBeanDefinitions

protected BeanDefinition lookupBeanDefinitions(java.lang.String... names)

Lookups for first founded bean definition.

lookupExistingBeanDefinition

protected BeanDefinition lookupExistingBeanDefinition(java.lang.String name)

Lookups for existing bean. Throws exception if bean is not found.

isBeanNameRegistered

public boolean isBeanNameRegistered(java.lang.String name)

Returns true if bean name is registered.

resolveBeanName

public java.lang.String resolveBeanName(java.lang.Class type)

Resolves bean's name from bean annotation or type name. May be used for resolving bean name of base type during registration of bean subclass.

registerPetiteBean

public BeanDefinition registerPetiteBean(java.lang.Class type,
                                         java.lang.String name,
                                         java.lang.Class<? extends Scope> scopeType,
                                         WiringMode wiringMode,
                                         boolean define)

Registers or defines a bean.

Parameters:

type - bean type, must be specified

name - bean name, if null it will be resolved from the class (name or annotation)

scopeType - bean scope, if null it will be resolved from the class (annotation or default one)

wiringMode - wiring mode, if null it will be resolved from the class (annotation or default one)

define - when set to true bean will be defined - all injection points will be set to none

removeBean

public void removeBean(java.lang.Class type)

Removes all petite beans of provided type. Bean name is not resolved from a type! Instead, all beans are iterated and only beans with equal types are removed.

See Also:

removeBean(String)

removeBean

public BeanDefinition removeBean(java.lang.String name)

Removes bean and returns definition of removed bean. All resolvers references are deleted, too. Returns bean definition of removed bean or null.
