Method Details

asObject

public final V asObject()

Description copied from interface: Value

This returns a java standard library representation of the underlying value, using a java type that is "sensible" given the underlying type. The mapping for common types is as follows:

• TypeSystem.NULL() - null
• TypeSystem.LIST() - List
• TypeSystem.MAP() - Map
• TypeSystem.BOOLEAN() - Boolean
• TypeSystem.INTEGER() - Long
• TypeSystem.FLOAT() - Double
• TypeSystem.STRING() - String
• TypeSystem.BYTES() - byte[]
• TypeSystem.DATE() - LocalDate
• TypeSystem.TIME() - OffsetTime
• TypeSystem.LOCAL_TIME() - LocalTime
• TypeSystem.DATE_TIME() - ZonedDateTime
• TypeSystem.LOCAL_DATE_TIME() - LocalDateTime
• TypeSystem.DURATION() - IsoDuration
• TypeSystem.POINT() - Point
• TypeSystem.NODE() - Node
• TypeSystem.RELATIONSHIP() - Relationship
• TypeSystem.PATH() - Path

Note that the types in TypeSystem refers to the Neo4j type system where TypeSystem.INTEGER() and TypeSystem.FLOAT() are both 64-bit precision. This is why these types return java Long and Double, respectively.
