Method Details

isEmpty

public boolean isEmpty()

Description copied from interface: Value

If this value represents a list or map, test if the collection is empty.

Specified by:

isEmpty in interface Value

Overrides:

isEmpty in class ValueAdapter

Returns:

true if size() is 0, otherwise false

size

public int size()

Description copied from interface: Value

If the underlying value is a collection type, return the number of values in the collection.

For TypeSystem.LIST() list} values, this will return the size of the list.

For map values, this will return the number of entries in the map.

For node and TypeSystem.RELATIONSHIP() relationship} values, this will return the number of properties.

For path values, this returns the length (number of relationships) in the path.

Specified by:

size in interface MapAccessor

Specified by:

size in interface Value

Overrides:

size in class ValueAdapter

Returns:

the number of values in an underlying collection

asObject

public String 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.

Specified by:

asObject in interface Value

Overrides:

asObject in class ValueAdapter

Returns:

the value as a Java Object.

asString

public String asString()

Specified by:

asString in interface Value

Overrides:

asString in class ValueAdapter

Returns:

the value as a Java String, if possible.

toString

public String toString()

Specified by:

toString in interface Value

Specified by:

toString in class ValueAdapter

type

public Type type()

Returns:

The type of this value as defined in the Neo4j type system

equals

public boolean equals(Object o)

Specified by:

equals in interface Value

Specified by:

equals in class ValueAdapter

hashCode

public int hashCode()

Specified by:

hashCode in interface Value

Specified by:

hashCode in class ValueAdapter
