public class CustomConversions
extends Object

SimpleTypeHolder	getSimpleTypeHolder() Returns the simple type holder.
boolean	hasCustomReadTarget(Class<?> sourceType, Class<?> requestedTargetType) Returns whether we have a custom conversion registered to read the given source into the given target type.
boolean	hasCustomWriteTarget(Class<?> sourceType) Returns whether we have a custom conversion registered to write into a Couchbase native type.
boolean	hasCustomWriteTarget(Class<?> sourceType, Class<?> requestedTargetType) Returns whether we have a custom conversion registered to write an object of the given source type into an object of the given Couchbase native target type.

public SimpleTypeHolder getSimpleTypeHolder()

Returns the simple type holder.

Returns:

the simple type holder.

registerConvertersIn

public void registerConvertersIn(GenericConversionService conversionService)

Populates the given GenericConversionService with the convertes registered.

Parameters:

conversionService - the service to register.

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 Couchbase native one.

Parameters:

sourceType - must not be null

Returns:

getCustomWriteTarget

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

Returns the target type we can write an object of the given source type to. The returned type might be a subclass oth 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.
