Method Details

getResolvers

public ArgumentResolverComposite getResolvers()

setResolvers

@Autowired
public void setResolvers(ContextArgumentResolverComposite resolvers)

isInstanceNameDefined

public boolean isInstanceNameDefined(Class<?> aClass)

Description copied from interface: InstanceNameProvider

Checks if InstanceName annotation is present in an entity class, i.e. whether instance name can be obtained for entity instances.

Specified by:

isInstanceNameDefined in interface InstanceNameProvider

Parameters:

aClass - an entity class to check

Returns:

true if InstanceName annotation is present, false otherwise

getInstanceName

public String getInstanceName(Object instance)

Description copied from interface: InstanceNameProvider

Gets entity instance name defined by InstanceName annotation. If InstanceName annotation is not defined, returns entity.toString().

Specified by:

getInstanceName in interface InstanceNameProvider

Parameters:

instance - an entity instance to get instance name

Returns:

instance name

getInstanceName

public String getInstanceName(Object instance,
 Class<?> clazz)

Description copied from interface: InstanceNameProvider

Gets entity instance name defined by InstanceName annotation in entityClass or its ancestor if CoreProperties.instanceNameFallbackEnabled is true.

Specified by:

getInstanceName in interface InstanceNameProvider

Parameters:

instance - instance

clazz - class to get @InstanceName definition from

Returns:

instance name

See Also:

• CoreProperties.instanceNameFallbackEnabled

getInstanceName

public String getInstanceName(Object instance,
 MetaClass metaClass)

Description copied from interface: InstanceNameProvider

Gets entity instance name defined by InstanceName annotation in metaClass or its ancestor if CoreProperties.instanceNameFallbackEnabled is true.

Specified by:

getInstanceName in interface InstanceNameProvider

Parameters:

instance - instance

metaClass - class to get @InstanceName definition from

Returns:

instance name

See Also:

• CoreProperties.instanceNameFallbackEnabled

getInstanceName

protected InstanceNameProviderImpl.EvaluationResult getInstanceName(InstanceNameProviderImpl.InstanceNameRec rec,
 Object instance)

getInstanceNameRelatedProperties

public Collection<MetaProperty> getInstanceNameRelatedProperties(MetaClass metaClass,
 boolean useOriginal)

Description copied from interface: InstanceNameProvider

Return a collection of properties included into entity's name pattern (see InstanceName).

Specified by:

getInstanceNameRelatedProperties in interface InstanceNameProvider

Parameters:

metaClass - entity metaclass

useOriginal - if true, and if the given metaclass doesn't define a InstanceName and if it is an extended entity, this method tries to find a name pattern in an original entity

Returns:

collection of the name pattern properties

getInstanceNameProperties

protected Collection<MetaProperty> getInstanceNameProperties(MetaClass metaClass,
 @Nullable
 Method nameMethod,
 @Nullable
 MetaProperty nameProperty)

parseNamePattern

@Nullable
public InstanceNameProviderImpl.InstanceNameRec parseNamePattern(MetaClass metaClass)
