io.inverno.core.annotation.Bean.Strategy

All Implemented Interfaces:

Serializable, Comparable<Bean.Strategy>, Constable

Enclosing class:

Bean

public static enum Bean.Strategy
extends Enum<Bean.Strategy>

Indicates the strategy to use to instantiate the bean.

A SINGLETON bean is only instantiated once in a module and this single instance is returned when requested. As a result any dependent bean share the same instance. This is the default behavior when no scope is specified.

A PROTOTYPE bean is instantiated each time it is requested which means every dependent beans receive distinct instances.

Note that this attribute is irrelevant and therefore ignored when specified on a socket bean

Since:

1.0
