Constructor Detail

CustomConversions

public CustomConversions()

Creates an empty CustomConversions object.

CustomConversions

public CustomConversions(List<?> converters)

Creates a new CustomConversions instance registering the given converters.

Parameters:

converters -

Method Detail

getSimpleTypeHolder

public SimpleTypeHolder getSimpleTypeHolder()

Returns the underlying SimpleTypeHolder.

Returns:

isSimpleType

public boolean isSimpleType(Class<?> type)

Returns whether the given type is considered to be simple. That means it's either a general simple type or we have a writing Converter registered for a particular type.

Parameters:

type -

Returns:

registerConvertersIn

public void registerConvertersIn(GenericConversionService conversionService)

Populates the given GenericConversionService with the convertes registered.

Parameters:

conversionService -

getCustomWriteTarget

public Class<?> getCustomWriteTarget(Class<?> sourceType)

Returns the target type to convert to in case we have a custom conversion registered to convert the given source type into a Redis native one.

Parameters:

sourceType - must not be null

Returns:

getCustomWriteTarget

public Class<?> getCustomWriteTarget(Class<?> sourceType,
                                     Class<?> requestedTargetType)

Returns the target type we can readTargetWriteLocl an inject of the given source type to. The returned type might be a subclass of the given expected type though. If expectedTargetType is null we will simply return the first target type matching or null if no conversion can be found.

Parameters:

sourceType - must not be null

requestedTargetType -

Returns:

hasCustomWriteTarget

public boolean hasCustomWriteTarget(Class<?> sourceType)

Returns whether we have a custom conversion registered to readTargetWriteLocl into a Redis native type. The returned type might be a subclass of the given expected type though.

Parameters:

sourceType - must not be null

Returns:

hasCustomWriteTarget

public boolean hasCustomWriteTarget(Class<?> sourceType,
                                    Class<?> requestedTargetType)

Returns whether we have a custom conversion registered to readTargetWriteLocl an object of the given source type into an object of the given Redis native target type.

Parameters:

sourceType - must not be null.

requestedTargetType -

Returns:

hasCustomReadTarget

public boolean hasCustomReadTarget(Class<?> sourceType,
                                   Class<?> requestedTargetType)

Returns whether we have a custom conversion registered to readTargetReadLock the given source into the given target type.

Parameters:

sourceType - must not be null

requestedTargetType - must not be null

Returns:
