Class SimplePropertyValueConversions

java.lang.Object

org.springframework.data.convert.SimplePropertyValueConversions

All Implemented Interfaces:

InitializingBean, PropertyValueConversions

public class SimplePropertyValueConversions
extends Object
implements PropertyValueConversions, InitializingBean

PropertyValueConversions implementation that allows to pick a PropertyValueConverterFactory serving converters. Activating cahing allows to reuse converters. Providing a SimplePropertyValueConverterRegistry adds path configured converter instances.

Should be initialized. If not, init() will be called of fist attempt of converter retrieval.

2.7

SimplePropertyValueConversions

public SimplePropertyValueConversions()

Method Details

setConverterFactory

public void setConverterFactory(PropertyValueConverterFactory converterFactory)

Set the factory responsible for creating the actual converter.

Parameters:

converterFactory - must not be null.

getConverterFactory

@Nullable
public PropertyValueConverterFactory getConverterFactory()

setValueConverterRegistry

public void setValueConverterRegistry(ValueConverterRegistry<?> valueConverterRegistry)

Set the converter registry for path configured converters. This is short for adding a PropertyValueConverterFactories.ConfiguredInstanceServingValueConverterFactory at the end of a PropertyValueConverterFactories.ChainedPropertyValueConverterFactory.

Parameters:

valueConverterRegistry - must not be null.

getValueConverterRegistry

@Nullable
public ValueConverterRegistry<?> getValueConverterRegistry()

Get the ValueConverterRegistry used for path configured converters.

Returns:

can be null.

setConverterCacheEnabled

public void setConverterCacheEnabled(boolean converterCacheEnabled)

Dis-/Enable caching. Enabled by default.

Parameters:

converterCacheEnabled - set to true to enable caching of converter instances.

hasValueConverter

public boolean hasValueConverter(PersistentProperty<?> property)

Description copied from interface: PropertyValueConversions

Check if a PropertyValueConverter is present for the given property.

Specified by:

hasValueConverter in interface PropertyValueConversions

Parameters:

property - must not be null.

Returns:

true if a specific PropertyValueConverter is available.

getValueConverter

@Nullable
public <DV,
SV,
C extends PersistentProperty<C>,
D extends ValueConversionContext<C>>
PropertyValueConverter<DV,SV,D> getValueConverter(C property)

Description copied from interface: PropertyValueConversions

Get the PropertyValueConverter for the given property.

Specified by:

getValueConverter in interface PropertyValueConversions

Type Parameters:

DV - domain-specific type

SV - store-native type

C - conversion context type

Parameters:

property - must not be null.

Returns:

the suitable PropertyValueConverter.

init

public void init()

May be called just once to initialize the underlying factory with its values.

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Specified by:

afterPropertiesSet in interface InitializingBean

Throws:

Exception
