decompose

public Map<K, org.neo4j.driver.Value> decompose(@Nullable Map<K,Object> property,
 Neo4jConversionService conversionService)

Description copied from interface: Neo4jPersistentPropertyToMapConverter

Decomposes an object into a map. A conversion service is provided in case delegation is needed.

Specified by:

decompose in interface Neo4jPersistentPropertyToMapConverter<K, Map<K,Object>>

Parameters:

property - the source property

conversionService - the conversion service to delegate to if necessary

Returns:

the decomposed object.

compose

public Map<K,Object> compose(Map<K, org.neo4j.driver.Value> source,
 Neo4jConversionService conversionService)

Description copied from interface: Neo4jPersistentPropertyToMapConverter

Composes the object back from the map. The map contains the raw driver values, as SDN cannot know how you want to handle them. Therefore, the conversion service to convert driver values is provided.

Specified by:

compose in interface Neo4jPersistentPropertyToMapConverter<K, Map<K,Object>>

Parameters:

source - the source map

conversionService - the conversion service in case you want to delegate the work for some values in the map

Returns:

the composed object.
