Class AnnotationConfigurerAdapter<O,I,B extends AnnotationBuilder<O>>

java.lang.Object

org.springframework.statemachine.config.common.annotation.AnnotationConfigurerAdapter<O,I,B>

Type Parameters:

O - The Object being built by B

I - The interface of type B

B - The Builder that is building O and is configured by AnnotationConfigurerAdapter

All Implemented Interfaces:

AnnotationConfigurer<O,B>

Direct Known Subclasses:

AbstractTransitionConfigurer, DefaultChoiceTransitionConfigurer, DefaultConfigurationConfigurer, DefaultDistributedStateMachineConfigurer, DefaultEntryTransitionConfigurer, DefaultExitTransitionConfigurer, DefaultForkTransitionConfigurer, DefaultHistoryTransitionConfigurer, DefaultJoinTransitionConfigurer, DefaultJunctionTransitionConfigurer, DefaultModelConfigurer, DefaultMonitoringConfigurer, DefaultPersistenceConfigurer, DefaultPropertiesConfigurer, DefaultResourceConfigurer, DefaultSecurityConfigurer, DefaultStateConfigurer, DefaultVerifierConfigurer

public abstract class AnnotationConfigurerAdapter<O,I,B extends AnnotationBuilder<O>>
extends Object
implements AnnotationConfigurer<O,B>

A base class for AnnotationConfigurer that allows subclasses to only implement the methods they are interested in. It also provides a mechanism for using the AnnotationConfigurer and when done gaining access to the AnnotationBuilder that is being configured.

AnnotationConfigurerAdapter

public AnnotationConfigurerAdapter()

Method Details

init

public void init(B builder)
          throws Exception

Description copied from interface: AnnotationConfigurer

Initialise the AnnotationBuilder. Here only shared state should be created and modified, but not properties on the AnnotationBuilder used for building the object. This ensures that the AnnotationConfigurer.configure(AnnotationBuilder) method uses the correct shared objects when building.

Specified by:

init in interface AnnotationConfigurer<O,I>

Parameters:

builder - the builder

Throws:

Exception - if error occurred

configure

public void configure(B builder)
               throws Exception

Description copied from interface: AnnotationConfigurer

Configure the AnnotationBuilder by setting the necessary properties on the AnnotationBuilder.

Specified by:

configure in interface AnnotationConfigurer<O,I>

Parameters:

builder - the builder

Throws:

Exception - if error occurred

and

public I and()

Return the AnnotationBuilder when done using the AnnotationConfigurer. This is useful for method chaining.

Returns:

the AnnotationBuilder

getBuilder

protected final B getBuilder()

Gets the AnnotationBuilder. Cannot be null.

Returns:

the AnnotationBuilder

Throws:

IllegalStateException - if AnnotationBuilder is null

addObjectPostProcessor

public void addObjectPostProcessor(ObjectPostProcessor<?> objectPostProcessor)

Adds an ObjectPostProcessor to be used for this adapter. The default implementation does nothing to the object.

Parameters:

objectPostProcessor - the ObjectPostProcessor to use

setBuilder

public void setBuilder(B builder)

Sets the AnnotationBuilder to be used. This is automatically set when using AbstractConfiguredAnnotationBuilder.apply(AnnotationConfigurerAdapter)

Parameters:

builder - the AnnotationBuilder to set

isAssignable

public boolean isAssignable(AnnotationBuilder<O> builder)

Specified by:

isAssignable in interface AnnotationConfigurer<O,I>
