valueType

public org.neo4j.gds.api.nodeproperties.ValueType valueType()

Specified by:

valueType in interface PropertyValues

dimension

public java.util.Optional<java.lang.Integer> dimension()

Description copied from interface: NodePropertyValues

The dimension of the properties. For scalar values, this is 1. For arrays, this is the length of the array stored for the 0th node id. If that array is null, this method returns Optional.empty().

Specified by:

dimension in interface NodePropertyValues

Returns:

the dimension of the properties stored, or empty if the dimension cannot easily be retrieved.

getMaxLongPropertyValue

public java.util.OptionalLong getMaxLongPropertyValue()

Specified by:

getMaxLongPropertyValue in interface NodePropertyValues

Returns:

the maximum long value contained in the mapping or an empty OptionalLong if the mapping is empty or the feature is not supported.

getMaxDoublePropertyValue

public java.util.OptionalDouble getMaxDoublePropertyValue()

Specified by:

getMaxDoublePropertyValue in interface NodePropertyValues

Returns:

the maximum double value contained in the mapping or an empty OptionalDouble if the mapping is empty or the feature is not supported.

nodeCount

public long nodeCount()

Specified by:

nodeCount in interface NodePropertyValues
